Hey there! :)

Answer:

r ≈ 4.38 cm.

Step-by-step explanation:

Find the radius by working backwards using the equation A = πr²:

Given:

A = 60.24 cm²

π = 3.14

Plug these into the equation:

60.24 = 3.14r²

Divide both sides by 3.14:

19.185 = r²

Take the square root of both sides:

r ≈ 4.38 cm.

Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at

Marianna [84]

Answer:

Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 4.01

Sample mean, $\bar{x}$ = 4.4

Sample size, n = 15

Alpha, α = 0.1

Sample standard deviation, s = 1.6 minutes

First, we design the null and the alternate hypothesis

$H_{0}: \mu \leq 4.01\\H_A: \mu > 4.01$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{4.4 - 4.0}{\frac{1.6}{\sqrt{15}} } = 0.968$

Option B) 0.968

Rejection region:

Now, $t_{critical} \text{ at 0.10 level of significance, 9 degree of freedom } = 1.345$

So the rejection region would be a value of t-statistic greater than 1.345.

Option B) t > 1.345

Conclusion:

Since,

$t_{stat} < t_{critical}$

We fail to reject the null hypothesis and accept the null hypothesis. Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Share £56 in the ratio 1:3:4

Rus_ich [418]

First u do 1+3+4 which gives u 8...then divide it from the number 56 which gives u 7..then after do (multiplication) 1*7= £7...then 3*7=£21 and then 4*7=£28....ur answer is £7.00, £21.00 and £28.00.....to check them if it's right u could do 7+21+28 which gives u exactly £56.00...so yap hope this helped u :)

How to do y=mx+b for the problem 4x-11y=-6

Aleks [24]

Simply rearrange the terms and simplify.

Subtracting 4x from both sides, we have:

-11y=-4x-6

Dividing by -11, we have:

$y= \frac{4}{11} \cdot x + \frac{6}{11}$

This is in the proper form, so this is our final equation.
