Answer:
k = 8
Step-by-step explanation:
Given
= 
( cross- multiply )
3k = 24 ( divide both sides by 3 )
k = 8
Answer:
125in³
Step-by-step explanation:
A box that would perfectly fit the bowling ball will be a cube shape.
The box will have the dimensions 5in by 5in by 5in. These dimensions come from the diameter for the ball.
Calculate volume using V = s³, where "s" stands for a side.
V = s³
V = (5in)³
V = 125in³
Mr. Ryan needs a box with the volume 125 cubic inches.
Answer:
1.38
Step-by-step explanation:
2 cups is one pint so if 3/4 is .38 then you would put it together to get 1.38
Answer:
Step-by-step explanation:
<em>Step 1: Define significance level</em>
In this hypothesis testing problem, significance levels α is selected: 
, the associated z-value from Laplace table:
Φ(
) = α - 
=> = 
<em>Step 2: Define null hypothesis (</em>
<em>) and alternative hypothesis (</em>
<em>)</em>
: rate of flu infection 
= 8.3% or 8.3/100 = 0.083
: rate of flu infection < 8.3% or 8.3/100 = 0.083
<em>Step 3: Apply the formula to check test statistic:</em>
with 
is actual sampling percent, is rate of flu infection of , 
is number of samples.
The null hypothesis will be rejected if 
<em>Step 4: Calculate the value of K and compare with </em>
We have 
=>This is good evidence to reject null hypothesis.
=> The actual rate is lower. (As states)
Hope this helps!
