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,
= 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
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Option B) 0.968
Rejection region:
Now,
So the rejection region would be a value of t-statistic greater than 1.345.
Option B) t > 1.345
Conclusion:
Since,

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.

Step-by-step explanation:
Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Answer:
D
Step-by-step explanation:
Please refer to the attachment below.
We have a 30-60-90 triangle.
Hence, the ratios of the sides will be related as shown in the triangle below.
Let’s determine the value of x. In a 30-60-90 triangle, the hypotenuse is 2x.
Here, our hypotenuse is 10.
Then it follows that:

The side opposite to ∠A (60) is CB.
And it is x√3.
Hence, CB is 5√3.
The side opposite to ∠B (30) is AC.
And it is x.
Hence, AC is 5.
Therefore, AC is 5 while BC is 5√3.
Hence, our answer is D.
