Answer:

624

Step-by-step explanation:

Width: 104

Length: 208

104+104+208+208=624

Answer: 624

Step-by-step explanation: We know the width is 104 inches and that the length is twice that. So since 104 times 2 = 208 the length must be 208

to get the perimeter we must add length + length + width + width

so 104 +104+208+208 if we add 104 + 104 =208 so...

208+208+208= perimeter or 208 times 3 = perimeter

so multiply 208 times 3 and you will get 624 which is the perimeter

hope this helps mark me brainliest if it did

A solid object is dropped into a pond with a temperature of 20 degrees Celsius. The function f(t)=Ce(−kt)+20 represents the situ
LenaWriter [7]

Answer:

The initial temperature of the object was 37.6 degrees Celsius

The initial temperature of the object was 37.6 (without units)

Step-by-step explanation:

we have

f(t)=Ce^{(-kt)} +20

where

f(t) represent the temperature of the object in degree Celsius

t is the time in minutes

<em>Find the value of the constant C</em>

we have the ordered pair (4,35)

substitute in the equation and solve for C

35=Ce^{(-0.0399*4)} +20

Ce^{(-0.0399*4)}=15

C=15/e^{(-0.0399*4)}

C=17.6

Find the initial value of the object

we know that

The initial temperature is the value of f(t) when the value of t is equal to zero

so

For t=0

f(0)=(17.6)e^{(-k*0)} +20

f(0)=17.6 +20

f(0)=37.6\ degrees\ Celsius

therefore

The initial temperature of the object was 37.6 degrees Celsius

The initial temperature of the object was 37.6 (without units)

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.
