g(x)=3x^2-2(x+7)/2x+5

g(-1)=3(-1)^2-2(-1)+7/2(-1)+5

Do the numerator first

(3)(-1)(-1)-2(-1)+7

3+2+7

=12

2(-1)+5

-2+5

=3

Numerator= 12 , Denominator=3

Numerator/ Denominator = 12/3=4

Answer: g(-1)=4

<h3>Answer:</h3><h3>\large\boxed{g(-1)=4}</h3><h3>Step-by-step explanation:</h3>

In this question. we would be plugging in -1 to all of the x variables.

The equation we are solving is:

g(x)=\frac{3x^2-2x+7}{2x+5}

You would plug in -1 to all of the x variables.

Your equation should look like this:

g(x)=\frac{3(-1)^2-2(-1)+7}{2(-1)+5}

Now, you solve:

g(x)=\frac{3(-1)^2-2(-1)+7}{2(-1)+5}\\\\\text{Lets start with the top}\\\\g(x)=\frac{3(1)-2(-1)+7}{2(-1)+5}\\\\g(x)=\frac{3-2(-1)+7}{2(-1)+5}\\\\g(x)=\frac{3+2+7}{2(-1)+5}\\\\g(x)=\frac{12}{2(-1)+5}\\\\\text{We can do the bottom now}\\\\g(x)=\frac{12}{2(-1)+5}\\\\g(x)=\frac{12}{-2+5}\\\\g(x)=\frac{12}{3}\\\\\text{Divide the fraction}\\\\g(-1)=4

When you're done solving, you should get 4.

This means that when g is -1, the answer would be 4.

g(-1) = 4

3x+y=4<br> 2x+y=5<br> solve using linear combination
Advocard [28]
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7

drug sniffing dogs must be 95% accurate in their responses because their handlers don't want them to miss durgs and also don't w
GenaCL600 [577]

Answer:

95% Confidence interval:  (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

\hat{p} = \dfrac{x}{n} = \dfrac{46}{50} = 0.92

95% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting the values, we get:

0.92 \pm 1.96(\sqrt{\dfrac{0.92(1-0.92)}{50}})\\\\ = 0.92\pm 0.0751\\\\=(0.8449,0.9951)

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.

Anna [14]

Answer:

Step-by-step explanation:

The pediatrician said that the z-score for the boy's height, relative to other 2-year-olds in the country, was 1.59

He explains to the parents of the boy, that the extreme 5% of cases often require special attention.

(A) Does this child fall into that group?

Yes, this child falls into that group. He is among the extreme 5% of cases at the tail of the distribution.

(B) What do you need to assume about the heights of 2-year-olds, in order to find your answer to part (A)?

Assume that the distribution of heights is skewed, the heights are independent of one another, and the number of heights is very large.
