Please guys I am begging you to help me! This was due yesterday and I need help! SO please help!

jeka57 [31]

Answer:

Q3. 12 units
Q4. 6.33 units
Q5. 66.19°

Step-by-step explanation:

Q3

DE and DF are legs and EF is hypotenuse

DE = √EF² - DF²
DE = √13² - 5² = √169 - 25 = √ 144 = 12
DE = 12 units

Q4

PR is opposite side of angle Q and RQ is adjacent side

tan 54 = PR/RQ
tan 54 = PR / 4.6
PR = 4.6tan 54
PR = 6.33 units

Q5

As previous question, using tan as BC is opposite and AC is adjacent leg of angle A

tan A = 6.8/3
tan A = 2.266
A = arctan (2.266)
A = 66.19°

What is the sqaure root of 2309!!!??

Serggg [28]

Answer:

the answer is approximately 48.05.

Step-by-step explanation: You can either use a calculator or estimate knowing that 50 is the square root of 2500, which is slightly above 2309. You can also use differentials and calculus to find an approximation.

Suki split five dog treats equally among her six dogs. Which fraction represents this division.

anzhelika [568]

5 treats divided by six groups of one dog, or in easier terms, five dog treats divided up for 6 dogs. As a fraction, just remove the words except for 5, divided by, and 6, to give you 5/6. Hope this helped.

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.

Let $\mu$ = mean power consumption of microwave ovens.

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

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

Here, null hypothesis states that the mean power consumption of microwave ovens is no more than 250 W.

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

The test statistics that would be used here is One-sample z test statistics 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.
