3/5 =6/10, so 6/10-1/10 = 5/10 =200. 1/2 of 200=100, so mrs.kleein made 400 fruit buns in all.

Answer:

I just realized wasn't answering the question in the answer box.

Not sure if you guys still need this but:

a) This is an experiment, because there are 2 groups randomly assigned to a treatment.

b) i. A larger percent of people who got ad 1 clicked it and made the purchase, 22/100, than the amount who clicked ad 2 and made the purchase, 16/100.

ii. A larger percent of people who got ad 2 clicked the ad overall 20+16= 36 so 36/100 than the percent of those who got as 1 and clicked it 22+8=30 so 30/100.

c) There is more than one way to do this, but I usually do it this way:

p(made a purchase | ad 2)= 16/100= 0.16

p(made a purchase)= 38/200= 0.19

p(made a purchase | ad 1)= 22/100= 0.11

The the two events are NOT independent, because 0.19 is NOT= 0.22 is NOT= 0.16. Therefore, the ad that the customer receives DOES affect the probability that they make the purchase.

d) When working with a sample proportion, the np>10 n(1-p)>10 rule is an important condition for normal approximation. In order to use a z-test to calculate the p-value the sample needs to be normal.

e) p1= 22/100= 0.22

p2= 16/100= 0.16

p1-p2= 0.22-0.16= 0.06

In this case the p-value means there is a 27.95% probability of getting a difference of sample proportions .06 or greater OR -.06 or lower.

f) The company should fail to reject the null hypothesis-- in this case there is NOT convincing evidence to support that there is a difference between the amount of people who click and as and purchase something and the amount of people who click ad 2 and purchase something.

Answer:

D

Step-by-step explanation:

add 3 to both sides to get x on its own: x>5

you find 5 on the number line, and then because x is greater it could be: 6, 7, 8, 9, 10, etc.

because of this the line points left.

) a rectangular box has length 12 inches, width 20 inches, and a height of 7 inches. find the angle between the diagonal of the
nlexa [21]

We assume the base is 12 in × 20 in, so its diagonal has length

... √(12² +20²) = √(144 +400) = √544 = 4√34 . . . inches

Then the tangent of the angle of interest is the ratio of the box height to the base diagonal:

... tan(α) = (7 in)/(4√34 in) ≈ 0.300123

The angle will be the arctangent of this value,

... α = arctan(7/√544) ≈ 0.291569 radians
