Pam jogged 15 and 3/4 miles in 3 hours. At this rate how long would it take Pam to jog 28 and 7/8 miles?
Lorico [155]
First, let’s find the distance Pam jogs in one hour.
15.75/3 = 5.25 mph.
Now, simply divide 28.875 (28 and decimal of 7/8) by our new rate.
28.875/5.25 = 5.5 hours. Choice B

The following confidence interval for the population proportion for how many U.S. adults do not get enough fruits and vegetables
Zielflug [23.3K]

Answer:

The interval is constructed at 93% confidence.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The margin of error is the difference between these two bounds, divided by 2.

Confidence interval of proportions concepts:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

In this problem, we have that:

2050 people, so n = 2050.

Lower bound: 0.878

Upper bound: 0.903

\pi = \frac{0.878 + 0.903}{2} = 0.8905

M = \frac{0.903 - 0.878}{2} = 0.0125

Confidence level:

We have to find z.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.0125 = z\sqrt{\frac{0.8905*0.1095}{2050}}

0.0069z = 0.0125

z = \frac{0.0125}{0.0069}

z = 1.81

z = 1.81 has a pvalue of 0.965.

That is:

]1 - \frac{\alpha}{2} = 0.965

\frac{\alpha}{2} = 0.035

\alpha = 2*0.035

\alpha = 0.07

Finally

1 - \alpha = 1 - 0.07 = 0.93

The interval is constructed at 93% confidence.

Find the y coordinate of the y intercept.
Sauron [17]

Answer:

5

Step-by-step explanation:

f(x+3) = (x+3)^2 - 4

factor (x+3)^2 using the formula (a+b)^2 = a^2 + 2ab + b^2

= x^2 + 6x + 9 - 4

= x^2 + 6x + 5

y-int : 5
