Answer:

x = -4 is not the solution to the equation because when you see the sign ≤ means there would be many numbers, can't count all of them but the answer would not be any specific number!

Hope this helped :3

Answer:

No

Step-by-step explanation:

To determine if x = - 4 is a solution to the inequality, substitute x = - 4 into the left side of the inequality and compare with right side.

5(- 4)² + 10(- 4) - 25

= (5 × 16) - 40 - 25 = 80 - 40 - 25 = 15 > 10

Since left side > right side then x = - 4 is not a solution

4.36 Stats final scores. Each year about 1500 students take the introductory statistics course at a large university. This year
velikii [3]

Answer:

The distribution of scores on this final exam is left-skewed.

Step-by-step explanation:

We use the Pearson Mode Skewness to solve this question. It states that:

If the median is higher than the mean, the distribution is left-skewed.

If the median is lower than the mean, the distribution is right-skewed.

If the median is the same as the mean, the distribution is symmetric.

In this problem, we have that:

Median = 74

Mean = 70

Median higher than the mean

So the distribution of scores on this final exam is left-skewed.

Solve for n.<br><br> 11(n – 1) + 35 = 3n<br><br> n = –6<br> n = –3<br> n = 3<br> n = 6
RSB [31]
Solve for n
Simply both sides 11(n-1)+35=3n
Distribute (11)(n) + (11)(-1) + 35 = 3n
11n+-11+35=3n
Combine like terms (11n)+(-11+35)=3n
11n + 24 =3n
Subtract 3n from both sides
11n+24-3n=3n-3n
8n + 24 = 0
Subtract 24 from both sides
8n+24-24=0-24
8n = -24
Divide both sides by 8
8n = -24
8 8
n = -3
