If all else remains constant and the values of two variables move in the same direction, it indicates a positive correlation.

  Correlation is a statistical measure that expresses the relationship between two variables. The correlation coefficient, which ranges from -1 to +1, is used to quantify the correlation.

 A positive correlation is when the values of the variables move in the same direction. A correlation of +1 indicates that the variables are perfectly positively correlated, implying that as one variable increases, the other also increases.

 A correlation of -1 indicates that the variables are perfectly negatively correlated, implying that as one variable increases, the other decreases. A correlation of zero indicates that there is no correlation between the variables.

   Hence a positive correlation exists when the values of two variables move in the same direction while all other factors remain constant.

The new mean cost of a box of Cheerios Out Crunch is $4.40. This means that, on average, customers can expect to pay $0.40 more for a box of cereal after the price increase.

The new mean cost of a box of Cheerios Out Crunch after a 10% increase in price would be $4.40.

To see why, we can start with the original mean cost of $4.00 per box. To calculate a 10% increase, we can multiply the original mean cost by 1.10 (or 110% as a decimal), which gives:

$4.00 x 1.10 = $4.40

The mean cost is the proportion of the cost of the multitude of items to the absolute number of items. In Maths, we likewise have the term called "normal". The normal of some random arrangement of information is known as the mean of information.

Step-by-step explanation:

Whatn the 5 highest is removed then standard deviation will decrease. (C)

The standard deviation is a measure of how spread out numbers are from the mean. Removing the 5 highest scores from the distribution of 20 scores will cause the numbers to become more concentrated around the mean, thus decreasing the standard deviation.

This is because the 5 highest scores are further away from the mean than the other numbers and by removing them, the average distance between the numbers and the mean decreases.

Mathematically, the formula for standard deviation is the square root of the sum of squared deviations from the mean divided by the number of scores minus 1.

When the 5 highest scores are removed, this means the sum of squared deviations from the mean is reduced, and since the number of scores is also reduced, the overall standard deviation value decreases.(C)

Answer:

120,000

Step-by-step explanation:

1.2 x 10^5 in standard form is 120,000.

To convert a number from scientific notation (with a power of 10) to standard form, you simply move the decimal point to the right or left depending on the sign of the exponent.

In this case, the exponent is positive, so we move the decimal point to the right by 5 places, filling in any empty spaces with zeros. This gives us the final answer of 120,000 in standard form.

Given the ratio of CD:DE:EF as 1:6:3 and CF as 20, we can use the sum of segment lengths equation to find the length of EF to be 12 units.

We're given that points C, D, E, and F lie on the same line segment in that order, with the ratio CD:DE:EF equal to 1:6:3. This means that the length of segment CD is 1x, the length of segment DE is 6x, and the length of segment EF is 3x, for some common factor x.

We're also given that CF (the total length of the segment from C to F) is equal to 20. So that we can set an equation:

CD + DE + EF = CF

Substituting the values we know from the ratio and CF:

1x + 6x + 3x = 20

Combining like terms:

10x = 20

Solving for x:

x = 2

Now we can use this value of x to find the lengths of each segment:

CD = 1x = 1(2) = 2

DE = 6x = 6(2) = 12

EF = 3x = 3(2) = 6

So the length of segment EF is 12 units.

Assuming the triangles in the pair above are similar, the value of x is equal to 11.

In Mathematics, the basic proportionality theorem states that when any of the two (2) sides of a triangle is intersected by a straight line which is parallel to the third (3rd) side of the triangle, then, the two (2) sides that are intersected would be divided proportionally and in the same ratio.

By applying the basic proportionality theorem to the given triangle, we have the following:

UV/VW = SU/ST

(5x + 11)/88 = 18/24

By cross-multiplying, we have the following:

24(5x + 11) = 18(88)

120x + 264 = 1,584

By rearranging and collecting like-terms, the value of x is given by:

120x = 1,584 - 264

120x = 1,320

x = 1,320/120

x = 11.

The new variance is  0.35.

The variance of a random variable measures how spread out the values are from the mean.

The formula for the variance is Var(X) = E[(X - E[X])²], where E[X] is the expected value (or mean) of X.

If the price of a box of Cheerios Oat Crunch increases by 25 cents, the new mean cost would be $4.25. To find the new variance, we can use the formula Var(aX + b) = a²Var(X), where a is a constant and b is a constant. In this case, a = 1 (because we are not changing the units of measurement) and b = 0.25 (because we are adding 25 cents to the price).

Therefore, the new variance is Var(X + 0.25) = Var(X) = Var(X) x 1² = Var(X) = 0.35.

This means that the variance remains the same even though the price has increased. This is because the variance is a measure of how spread out the values are from the mean, and the mean has shifted by the same amount as the price increase. Therefore, the distance between the values and the new mean is the same as the distance between the values and the old mean, so the spread is unchanged.

The variance is a measure of how spread out a set of data is from its mean. It is calculated as the average of the squared differences between each value and the mean. The formula for variance is Var(X) = E[(X - E(X))²], where E is the expected value or mean of X.

In this case, we are given that the mean cost of a box of Cheerios Oat Crunch is $4.00 and the variance is 0.35. This means that the average squared difference between each box's cost and the mean cost is 0.35.

Now, if the price of each box increases by 25 cents, this means that the new mean cost will be $4.25. However, this does not affect the variance directly. This is because the variance only measures how spread out the data is from the mean, and the mean has shifted by the same amount as the price increase.

To see this more clearly, imagine a set of data that has a mean of 4 and a variance of 0.35. If we add 0.25 to each value, we get a new set of data that has a mean of 4.25. However, the spread of the data is still the same; that is, the distance between each value and the new mean is the same as the distance between each value and the old mean. Therefore, the variance remains the same even though the price has increased.

In summary, the variance measures how spread out a set of data is from its mean, and a shift in the mean does not affect the variance directly.

Number of different page that numbers contain the digit 1 is 20

We can approach this problem by counting the number of pages that do not contain the digit 1 and subtracting that from the total number of pages, which is 200.

Let's count the number of pages that do not contain the digit 1. We can do this by considering each digit in turn. There are 9 choices for the first digit (it cannot be 1), and 10 choices for each of the remaining digits (since 1 is now allowed). So, there are 9 × 10 × 10 = 900 page numbers that do not contain the digit 1.

Therefore, the number of page numbers that do contain the digit 1 is 200 - 900 = -700.

However, this answer does not make sense since we cannot have negative page numbers. Therefore, there must be a mistake in our calculation. The mistake occurs when we consider the case where the first digit is 1. In this case, there are only 2 digits left to choose from (0 and 2-9), not 10. So, the correct number of page numbers that do not contain the digit 1 is 9 × 2 × 10 = 180.

Therefore, the number of page numbers that do contain the digit 1 is 200 - 180 = 20.

what is a decimal number?

A decimal number is a real number that is expressed in the decimal system, which is a system of numeration using the base 10. In this system, each digit can take on one of ten possible values, 0 through 9, and the value of each digit is determined by its position relative to the decimal point.

To compare the numbers √49 and 7.1212, we need to find their numerical values.

√49 = 7, since 7 multiplied by itself gives 49.

7.1212 is already a decimal number, so no calculation is required.

To approximate 7.1212, we can look at the digits after the decimal point:7.1212

0.1212

--------

7.0000 + 0.1212

--------

Answer: Therefore, the area that is only planted in corn can be expressed as the polynomial y^2 + 14y.

Step-by-step explanation:

The area of the square piece of land is given by the product of its length and width:

Area of square piece of land = (y + 7) * (y + 7)

The area of the small square that was planted with radish is 7 ft. by 7 ft. Therefore, its area is:

Area of small square = 7 * 7 = 49

The area that is only planted in corn is the difference between the area of the square piece of land and the area of the small square that was planted with radish:

Area planted in corn = (y + 7) * (y + 7) - 49

Expanding the expression on the right side, we get:

Area planted in corn = y^2 + 14y + 49 - 49

Simplifying further, we get:
