Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25
Answer:
1.070,0.1003
Step-by-step explanation:
Given that a random sample of n=1400 registered voters and found that 720 would vote for the Republican candidate in a state senate race.
p = the proportion of registered voters who would vote for the Republican candidate.
Sample proportion =
Hypotheses are:
(Right tailed test )
p difference =
Assuming null hypothesis to be true,
Std error =
a) Test statistic Z = p difference/std error = 1.070
b) When z =1.28, p value = 0.100273
$356 - $123 = $233, joshua spent $233
Answer:
3 cups
Step-by-step explanation:
We can use a proportion to find how many cups of chocolate chips she needs for 30 servings. Assuming c = cups of chocolate chips and b = batches
We can now multiply the diagonal values that don't include the missing variable (30 and 1) and then divide it by the value that is diagonal to the variable (10)
Therefore, she needs 3 cups of chocolate chips to make 30 servings.
