The value of y varies directly with x. If x = 3, then y = 4. What is the value of x when y = 120 ?

Answers

Answer:

x = 90

Step-by-step explanation:

If x = 3 and y = 4 then when y = 120 just find out what times 4 = 120

which is 30.

so just multiply 30 for x = 3, then the answer will be 90

x = 90

Answer:

x=90

Step-by-step explanation:

x is directly proportional to y

Therefore, if the initial y value was 4 and the final y value is 120. This means that y initial had been multiplied 120/4 times, which is 30.

Same goes for x. If x initial is 3, then the final x value would be x/3=30. This means that x=3×30, which is equal to 90.

Stefan sells Jin a bicycle for ​$146 and a helmet for ​$19. The total cost for Jin is 150​% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend​ originally? How much money did he make by selling the bicycle and helmet to​ Jin?

Answers

Stefan spend price $110 and made price $60 by selling bicycle and helmet to Jin.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100.

Here, given that,

Selling price of bicycle = $146

Selling price of helmet = $19

Total = 146+19= $165

Let,

x represents the original cost Stefan to buy the bike and helmet.

150% of x = $165

1.5x=$165

Dividing both sides by 1.5

we get ,

x=$110

Stefan bought bicycle and helmet for $110.

Profit made by Stefan = Selling price - buying price

Profit made by Stefan = 165-110= 55

Hence, Stefan spend price $110 and,  made $55 by selling bicycle and helmet to Jin.

For what value of a the system of equations Ax Y 2 and 6x 2y 3 has a unique solution?

Answers

A = 1, y = -2/3, The value of a for which the system of equations has a unique solution is a = -3.

1. Set the first equation equal to 0:

2x + ay = 2

2. Subtract 2x from both sides of the equation to get:

ay = -2

3. Divide both sides of the equation by a to get:

y = -2/a

4. Substitute this value of y into the second equation to get:

6x + 3(-2/a) = 3

5. Multiply both sides of the equation by a and simplify to get:

6ax - 6 = 3a

6. Add 6 to both sides of the equation to get:

6ax = 3a + 6

7. Divide both sides of the equation by 6 to get:

Answer:

Step-by-step explanation:

ABC + CBD is equal to 180 degrees

8x - 41 + 9x + 17 = 180

combine like terms

17x - 24 = 180

add 24 to both sides

17x = 204

divide both sides by 17

x = 12

then plug in to find CBD

9 (12) + 17

108 + 17 = 125 degrees

Answer:

angle CBD = 125°

Step-by-step explanation:

Because ABD is a straight angle we know it is equal to 180°

because we have this information we can create the equation

(8x-41) + (9x+17) = 180

17x - 24 = 180

(here you would add 24 to both sides)

17x = 204

(divide both sides by 17)

x = 12

Then you would plug in 12 for x in the equation for CBD which will then get you 125°

The brain volumes ?( cm cubed cm3?) of 20 brains have a mean of 1083. 9 1083. 9 cm cubed cm3 and a standard deviation of 122. 2 122. 2 cm cubed cm3. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such? data, would a brain volume of 1348. 3 1348. 3 cm cubed cm3 be significantly? high?

Answers

Therefore , the solution of standard deviation is  because the value of 1452.2 cm3 does not fall between the range of 917.4 cm3 and 1422.2 cm3.

what is the standard deviation?

Standard deviation, often known as variance in a set of data, is a statistical measure of variation. A low standard deviation indicates that the values are more likely to be near the mean of the collection, whereas a high standard deviation indicates that the values are widely distributed. How far the data depart from the mean is expressed by the standard deviation, abbreviated as.

Here,

Considering the details here,

The average brain volume is 1169.8 cm3, while the standard deviation is 126.2 cm3.

The much lower results are u-2 = 11169.8-2(126.2) => 917.4.

Reason: According to the range rule of thumb, the required incredibly low values are 91.7 cm3 or less.

Hint: Use the algorithm to identify values that are at least considerably high.

Step: 2

Considering the data supplied,

The average brain volume is 1169.8 cm3, while the standard deviation is 126.2 cm3.

Significantly higher values include,

u-2α = 11169.8+ 2(126.2)

=> 1422.2

Justification: According to the range rule of thumb, the necessary significantly high values must be 1422.2 cm3 or higher.

Hint: To determine whether the value 1452.2 cm3 is very high, use the findings of steps (1) and (2).

Step: 3

Using step 1 and step (4),

917.4 is among the significantly low numbers or less.

The significantly high values are 1422.2 or higher.

Yes, 1452.2 cm3 is a noticeably high value.

The apt response is choice (B).

Reason: The value is much higher than expected based on the range rule of thumb because the value of 1452.2 cm3 does not fall between the range of 917.4 cm3 and 1422.2 cm3.
