An appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W. From pre

Shtirlitz [24]

Answer:

Null Hypothesis, $H_0$ : $\mu \leq$ 250 W

Alternate Hypothesis, $H_A$ : $\mu$ > 250 W

Step-by-step explanation:

We are given that an appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W.

They take a sample of 20 microwave ovens and find that they consume a mean of 257.3 W.

<u><em>Let </em></u> $\mu$ <u><em> = mean power consumption of microwave ovens.</em></u>

So, Null Hypothesis, $H_0$ : $\mu \leq$ 250 W

Alternate Hypothesis, $H_A$ : $\mu$ > 250 W

Here, <u>null hypothesis states tha</u>t the mean power consumption of microwave ovens is no more than 250 W.

On the other hand, <u>alternate hypothesis sates that</u> the mean power consumption of microwave ovens is more than 250 W.

The test statistics that would be used here is <u>One-sample z test statistics</u> as we know about the population standard deviation;

T.S. = $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

Hence, this would be the appropriate hypotheses to determine if the manufacturer's claim appears reasonable.

To find the answer, you need to find the LCM of 3 and 5. It's 15, meaning that every 15 days, you will have both lessons on the same day. Have an awesome day! :)

A volleyball uniform costs $13 for the shirt, $11 for pants, and $8 for socks. Write two equivalent expressions for the total cost of 12 uniforms. Then find the cost.

Write an expression for the cost of 1 uniform, add $13, $11 and $8 .

$13+$11+$8

Write an expression for the cost of 12 uniforms, multiply 12 by the cost of 1 uniform.

12($13+$11+$8)

Simplify using the distributive property.

=12⋅13+12⋅11+12⋅8=156+132+96

Now Add.

=384

So, the total cost of 12 uniforms is $384 .

Answer:

h+r=34

r=34-h.....1

total surface area=2πr(r+h)

2992=2πr×34

2992/34=2πr

88/2=22/7×r

44×7/22=r

r=2×7=14cm
