Answer:
141 cookies
Step-by-step explanation:
amount of cookies
= 9(15) + 6
= 135 + 6
= 141
Answer:
x = 7
Step-by-step explanation:
When 2 secants are drawn from an external point to a circle.
The product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
5(5 + x) = 6(6 + 4) ← distribute and simplify both sides
25 + 5x = 6 × 10
25 + 5x = 60 ( subtract 25 from both sides )
5x = 35 ( divide both sides by 5 )
x = 7
Answer:
Probability: 0.7190
There is not enough evidence at the 5% level of significance to suggest that there is difference in proportions of red-light runners between the two intersections
Step-by-step explanation:
We can conduct a hypothesis test for the difference of 2 proportions. If there is no difference in proportion of red-light runners between the 2 lights, then the difference in proportions will be zero. That makes the null hypothesis
H0: p1 - p2 = 0
The question is asking whether there is a difference, meaning that the difference can be higher or lower. If there is a difference, the proportions are not equal. This makes the alternate hypothesis
Ha: p1 - p2 ≠ 0
This is a two tailed test
We will use a significance level of 95% to conduct our test. This makes the critical values for our test statistic: z > 1.96 or z < -1.96.
If our test statistic falls in either region, we will reject the null hypothesis.
See the attached photo for the hypothesis and conclusion
The z-value of the test statistic is z = 0.58.
P(z < 0.58) = 0.7190
Answer:
$82.50
Step-by-step explanation:
8.75 * 8 = 70
5 * 2.50 = 12.5
70 + 12.5 = 82.5
So, one employee would earn a total of $82.50 which also means that each employee earned $82.50
Answer:
A. a reflection over the x-axis and then a reflection over the y-axis
B. a reflection over the y-axis and then a reflection over the x-axis
Step-by-step explanation:
When you apply reflection over the x-axis, the transformation will change the y coordinate into -y. A similar thing happens when you do reflection over the y-axis, x coordinate will be -x. Both things will not influence each other so the sequence is not important. The resulting transformation will be equal to reflection to the point of origin.
