Answer 1

Answer:

0.4 or [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator ([tex]\frac{x}{30}[/tex]). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator ([tex]\frac{12}{y}[/tex]). Plug in the entire fraction and you get [tex]\frac{12}{30}[/tex]. Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get [tex]\frac{2}{5}[/tex]. Either one works, depending on what your question asks for.

2.7% of X equals 50,000. what is X?


don't give fake answers just for points YOU WILL BE REPORTED

Answers

Answer:

x = 1851851.851....

Step-by-step explanation:

Given statement:

2.7% of x equals 50,000.

When we convert the statement into an equation, we get;

⇒ 2.7% × x = 50,000

A percentage is always written as (Percent)/100 in fraction form. Thus;

⇒ 2.7/100 × x = 50,000

Using cross multiplication:

⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000

To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.

Divide both sides by 2.7

⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....

Answer:

Percent in decimal form:

[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]

Therefore:

27% of X = 50000

[tex]\sf \implies 0.027 \cdot X=50000[/tex]

[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]

[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]

[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]

[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]

you ordered 7.48 worth of food at sonic before tax . if tax is 7% , how much tax will you pay and whats the total .

Answers

Answer:

Tax = $0.5236

Total = $8

Step-by-step explanation:

$7.48 * 0.07(tax rate) = $0.5236

$0.5236 is the add-on tax you will pay at a rate of 7%

Simply add $0.5236 to your bill before tax of $7.48 to find your total of $8.0036

8.0036 is too low to round to a monetary value, so in total you would pay

approximately $8

The amount of time a certain brand of light bulb lasts is normally distributed with a
mean of 1400 hours and a standard deviation of 50 hours. Using the empirical rule,
determine what interval of hours represents the lifespan of the middle 68% of light
bulbs.

Answers

The interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.

What is empirical rule?

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here, we had  where mean of distribution of X is \mu  and standard deviation from mean of distribution of X is \sigma

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1400 hours and a standard deviation of 50 hours. Thus,

[tex]\mu=1300\\\sigma=90[/tex]

Using the empirical rule, the interval of hours represents the lifespan of the middle 68% of light bulbs is,

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(1300- 90 < X < 1300+ 90) = 68\%\\P(1210 < X < 1390) = 68\%[/tex]

Thus, the interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.

Assume that the weights of ripe watermelons grown at a particular farm are normally distributed with a mean of 30 pounds and a standard deviation of 1.9 pounds. If the farm produces 400 ​watermelons, how many will weigh less than 27.87 ​pounds?

Answers

Given↷Mean = 30Standard deviation = 1.9

Data value = 27.87To find↷

Number of watermelons out of 400 produced melons ,which will weigh < 27.87 poundsAnswer↷52Solution↷

We know that,

[tex] \rightarrow \: z = \frac{x - \mu}{\sigma} \\ [/tex]

z = standard scorex = measuring valueμ = meanσ =standard derivation

inserting the given values in the formula

[tex]\rightarrow \: z = \frac{27.87 - 30}{1.9} \\\rightarrow \: z = - 1.121[/tex]

Area that's left to z = -1.121

Area that's left to -1.121 = 0.1311

= 13.11%

Hence ,

13.11% of the watermelons weigh less than 27.87 pounds

To find the number of watermelons,

We'll find 13.11% of 400

= 13.11% x 400

= 13.11/100 x 400

= 52.44

hence , approx 52 watermelons would be lesser than 27.87 pounds

B) (x,y) → (x, y - 8)
C) (x, y) → (x, y + 8)
D) (x,y) → (x+8, y)

Answers

Answer:

A) (x, y) → (x - 8, y)

Step-by-step explanation:

Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.

A) (x, y) → (x - 8, y)

   (3, 7) → (3 - 8, y)

A. The curve is a linear function
B. The curve is a "many-to-one" function.
C. The curve is a "one-to-one" function.
D. The curve is not a function.

Answers

Answer:

Based on the curve ; The graph is:

       B. The curve is a many-to-one function.

Step-by-step explanation:

Function--

A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.

Also, the graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to the y-axis should intersect the graph exactly once.

and one-to-one function--

A one-to-one function is such that no two elements have the same image i.e. any line passing through the co-domain and parallel to the x-axis should intersect the graph at most once.

The graph passes the vertical line test and hence is a function.Also, the graph of a linear function is a straight line.

Hence, by looking at the graph we see that the graph is not a straight line.

Hence, it is not a linear function.

Also, it does not passes the horizontal line test (since somewhere in the interval (2,3) the same value is obtained many times )and hence it is not a one-to-one function

           Hence, the correct answer is:

Answers

Answer:20%

Step-by-step explanation:

Solution for 600 is what percent of 3000:

600:3000*100 =

( 600*100):3000 =

60000:3000 = 20

Now we have: 600 is what percent of 3000 = 20

Question: 600 is what percent of 3000?

Percentage solution with steps:

Step 1: We make the assumption that 3000 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that $100%=3000.

Step 4: In the same vein, x%=600.

Step 5: This gives us a pair of simple equations:

$100%=3000(1).

x%=600(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100% / %=3000/600

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=600/3000

--->=20%

Therefore, $600 is $20% of $3000.

PLEASE HELP ME! If an arithmetic sequence has a4 = 107 and a8 = 191, what is a₁? (I need the steps too please). ​

Answers

Answer:

[tex]\displaystyle a_1 = 44[/tex]

Step-by-step explanation:

Recall the direct formula for an arithmetic sequence:
[tex]\displaystyle a_n = a_1 + d(n-1)[/tex]

Where d is the common difference.

Therefore, we can write the following two equations:
[tex]\displaystyle \left \{ {a_4 = 107 = a_1 + d(4-1)\atop {a_8 = 191 = a_1 + d(8-1)}} \right.[/tex]

Solve the system. Simplifying yields:
[tex]\displaystyle 107 = a_1 + 3d\text{ and } 191 = a_1 + 7d[/tex]

Subtracting the two equations into each other yields:
[tex]\displaystyle \begin{aligned} (191) - (107) & = (a_1 + 7d) - (a_1 + 3d) \\ \\ 84 & = 4d \\ \\ d & = 21 \end{aligned}[/tex]

Using either equation, solve for the initial term:

[tex]\displaystyle \begin{aligned} 107 & = a_1 + 3(21) \\ \\ a_1 & = 107-63 \\ \\ & = 44\end{aligned}[/tex]

In conclusion, the initial term is 44.

Answer:

[tex]\huge\boxed{\bf\:a_{1} = 44}[/tex]

Step-by-step explanation:

In the given arithmetic series,

[tex]a_{4} = 107[/tex][tex]a_{8} = 191[/tex][tex]a_{1} = ?[/tex]

We know that,

[tex]\boxed{a_{n} = a + (n - 1)d}[/tex]

Therefore,

[tex]a_{4} = a + 3d = 107 -----(1)\\a_{8} = a + 7d = 191 -----(2)[/tex]

By solving the two equations (1) & (2)....

[tex]\:\:\:\:a + 7d = 191 \\-\underline{a + 3d = 107 }\\ \underline{\underline{\:\:\:\:\:\:\:\:\:\:\:\:\:4d = 84\:\:\:\:\:\:\:\:}}\\\\\\\\4d = 84\\d = 84 \div 4\\\boxed{d = 21}[/tex]

Now, we have the value of the common difference (d). To find [tex]a_{1}[/tex] or a, let's substitute the value of 'd' in (1).

[tex]a + 3d =107\\a + 3(21)=107\\a + 63 = 107\\a = 107 - 63\\\boxed{\bf\:a_{1} = 44}[/tex]
