Peter is trying to set a new record for pizza deliveries. His previous record is 20 pizzas in one hour. He has already delivered

Arlecino [84]

We know that
<span>Peter has already delivered </span><span> 2 pizzas in 5 minutes
so
1 hour-------> 60 minutes
</span><span>time left------> 60 minutes - 5 minutes--------> 55 minutes

</span>pizzas to deliver to beat his previous record----------> 20-2------> 18 pizzas

therefore
in the next 55 minutes

if the

<span>average per minute = (18/55) pizzas /minute
</span>Pete beat his previous record
<span>
</span>average per minute > (18/55) pizzas /minute
Pete overcome the previous record

average per minute < (18/55) pizzas /minute
Pete will not match the previous record

50% more than what number is 20% less than 60% more than 10?

k0ka [10]

Answer:

Step-by-step explanation:

Let's start by decoding this :)

First lets do 60% more than 10; 16 (mental math)

Next, lets do 20% less than 16; x/16 = 80/100 (Equation)

After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.

two angles are consecutive exterior to one another. if the angles are in ratio 11:7. Then find the supplement of the larger angl

Gwar [14]

If the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.

The larger angle and the smaller angle are supplementary to each other since they are consecutive exterior to one another.

<em><u>Thus</u></em>:

If the larger angle is x, therefore:

Ratio of Larger angle to smaller angle = 11:7

<em>Therefore</em>:

11x + 7x = 180 degrees

Solve for x

18x = 180

Divide both sides by 18

x = 10

Larger angle = 11x = 11(10) = 110 degrees

Smaller angle = 7x = 7(10) = 70 degrees

The supplement of the larger angle, 110 degrees, is <u>70 degrees.</u>

In summary, if the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Level of Significance, $\alpha = 0.05$

Sample Size, $n = 120$

Sample Proportion, $\hat{P} = 0.600$

$z -value = Z_{\frac{\alpha}{2}} = 1.960 \ \ [excel formula =NORMSINV(\frac{\alpha}{2})]$

Standard Error $SE = \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = 0.0447$

margin of error $E = Z\times SE = 1.960 \times 0.0447 = 0.0877$

When $95\%$ Confidence Interval

Interval Lower Limit $= \hat{p} - E = 0.600 - 0.0877 = 0.5123$

Interval Upper Limit $=\hat{p}+ E = 0.600 + 0.0877 = 0.6877$
