An isosceles trapezoid has a perimeter of 70.6 kilometers. Its shorter base measures 8.8 kilometers and its longer base measures

20.2 kilometers. The two remaining sides have the same length; what is that length?

Answer:

10.4

Step-by-step explanation: Given that;

perimeter p = 70.6 km

longer base b1 = 20.2 km

smaller base b2 = 8.8 km

The two remaining sides have the same length

I apply the formula:

L = P - ( b1 + b2)

L = [70.6 - ( 20.2 + 8.8 )]/2

L = 41.6/2 = 20.8

Since the two remaining sides have the same length

L/2 = 20.8/2 = 10.4

Suppose an article reported that 14% of unmarried couples in the United States are mixed racially or ethnically. Consider the po
Anvisha [2.4K]

Answer: \mu_{\hat{p}}=0.14 and \sigma_{\hat{p}}=0.0347

Step-by-step explanation:

In sampling distribution of \hat{p}.

The mean and standard deviation of the sampling distribution of p is given by :-

\mu_{\hat{p}}=p

\sigma_{\hat{p}}=\sqrt{\dfrac{p(1-p)}{n}}  , where p= population proportion and n= sample size.

Let p be the population proportion of unmarried couples in the United States are mixed racially or ethnically.

As per given , we have

n = 100

p= 14% =0.14

Then, the mean and standard deviation of the sampling distribution of p will be :

\mu_{\hat{p}}=0.14

\sigma_{\hat{p}}=\sqrt{\dfrac{0.14(1-0.14)}{100}}

\sigma_{\hat{p}}=\sqrt{\dfrac{0.14(0.86)}{100}}

\sigma_{\hat{p}}=\sqrt{\dfrac{0.1204}{100}}

\sigma_{\hat{p}}=\sqrt{0.001204}

\sigma_{\hat{p}}=0.0346987031458\approx0.0347

Hence, the required answer : \mu_{\hat{p}}=0.14 and \sigma_{\hat{p}}=0.0347

When fritz drives to work his trip takes 40 ​minutes, but when he takes the train it takes 30 minutes. find the distance fritz t
sweet-ann [11.9K]
Distance = rate*time

convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs

Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.

We know the time we know the speed, Next
distance that Fritz drive = \frac{2}{3}s
distance the train travel = \frac{1}{2}(s+15)

The question: Assume that the train travels the same distance as the car
==> \frac{2}{3}s = \frac{1}{2}(s+15)
==> \frac{2}{3}s = \frac{1}{2}s + \frac{15}{2}
==> \frac{2}{3}s - \frac{1}{2}s = \frac{15}{2}
==> \frac{1}{6}s = \frac{15}{2}
==> \frac{6}{1} * \frac{1}{6}s = \frac{15}{2} * \frac{6}{1}
==> s = 45 
Now we know that Fritz drive at 45 mph, 
distance = \frac{2}{3} * 45 = 30 miles
