Answer:

B) y = 3x - 5

Step-by-step explanation:

6x - 2y = 10

convert to y = mx + b, slope intercept form

6x - 2y = 10

<u>-6x          -6x</u>

-2y = -6x + 10

divide by -2

y = 3x - 5

Factor the polynomial:81m+48mn
Anton [14]
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.

So then you put 3 out the parentheses. 3(----).

Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.

So then this is what you get, 3(27m-16mn)

Hope it helps you!!!

Suppose 250 randomly selected people are surveyed to determine if they own a tablet. Of the 250 surveyed, 98 reported owning a t
SashulF [63]

Answer:

The true proportion for the population would be between 0.386 and 0,398 (0.392±0.06) in 95% confidence level.

Step-by-step explanation:

Confidence interval for true population proportion can be computed as p±ME where

  • p is the sample proportion ( \frac{98}{250}=0.392)
  • ME is the margin of Error from the mean

and margin of error (ME) can be found using the formula

ME=\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} } where

  • z is the corresponding statistic in 95% confidence level (1.96)
  • p is the sample proportion ( \frac{98}{250}=0.392)
  • N is the sample size (250)

Using the numbers

ME=\frac{1.96*\sqrt{0.392*0.608}}{\sqrt{250} } ≈ 0.06

Then the true proportion for the population would be p±ME = 0.392±0.06 in 95% confidence level.

ron’s class donated d dollars to a local charity. Danny’s class donated 21% more than Ron’s class. Which expression shows the am
Arte-miy333 [17]

You can clearly eliminate 0.79d as an answer, because that is less than the amount that Ron's class donated. The last answer is also incorrect, because it states that Danny's class donated 21 more cents than Ron's class. The problem says that Danny's class donated 21% more than Ron's. The only way that d + 0.21 would be correct is if Ron's class donated $1. The problem does not say that. Therefore, we are left with two possibilities. The first choice is the correct one. Why?

21% more than Ron's class' donation would be the amount that Ron's class donated + an additional 21%. If Ron's class donated d dollars, then an additional 21% would be 0.21 * d = 0.21d. Hence, Danny's class donated a total of:

d + 0.21d = d(1 + 0.21) = 1.21d

How do you solve this? Or what’s the answer?
pishuonlain [190]

Answer:

6.7

Step-by-step explanation:

Make a proportion (similar triangles):

(15) / (10+x) = 6/x

15x = 60 + 6x

9x = 60

x = 6.7
