Answer:

12 yards of silk

Step-by-step explanation:

okay so 1 yard = 36 inch so 2+3+6= 11 yards

now 1/2 of 36 is 18 inchs

6 inchs

and 1/3 of 36 is = 12

now add 12+18+6 = 36 = 1 extra yard so add that to 11 to get 12

How do I Express 18+24 as the product of the GCF and another sum

svp [43]

Answer:

$6(3+4)$

Step-by-step explanation:

We are asked to represent $18+24$ as the product of the GCF and another sum.

First of all, we will find the greatest common factor of 18 and 24.

Factors of 18: 1, 2, 3, 6, 9, 18.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.

We can see that greatest common factor of 18 and 24 is 6. Let us write our given expression as product.

$6\cdot 3+6\cdot 4$

Factor our 6:

$6(3+4)$

Therefore, our required expression would be $6(3+4)$ .

Suppose that your statistics professor tells you that the scores on a midterm exam were approximately

DedPeter [7]

Answer:

Step-by-step explanation:

z-score representing 85% is 1.04 (from table)

Let x be the score representing the lower limit of 85%.

Use the formula to find z-scores:

z = (x - μ)/σ

We have:

z = 1.04, μ = 78, σ = 7

Substitute the values and solve for x:

1.04 = (x - 78)/7
x - 78 = 7.28
x = 85.28

The lower limit of the top 15% is 85.28.

Since your score is greater than 85.28 you earned an A

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the di

Olin [163]

Solution: We are given:

ACT scores follow normal distribution with $\mu=20.9,\sigma =4.8$

SAT scores follow normal distribution with $\mu=1026,\sigma=209$

Now, let's find the z score corresponding to Joe's SAT score 1351.

$z=\frac{x-\mu}{\sigma}$

$=\frac{1351-1026}{209}$

$=\frac{325}{209}$

$=1.56$

Therefore, Joe's SAT score is 1.56 standard deviations above the mean.

Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.

Therefore, we have:

$z=\frac{x-\mu}{\sigma}$

$1.56=\frac{x-20.9}{4.8}$

$1.56 \times 4.8 = x - 20.9$

$7.488=x-20.9$

$x=20.9+7.488$

$x=28.388 \approx 28.4$

Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4

Which expression is equivalent to 4(3-6x)+x. Explain your reasoning. A.)-11x B.)-5x+12 C.)-23x+12 D.)37x

diamong [38]

C) -23x + 12 .. You're going to multiply the 4 to what's inside the parenthesis. So you'll get 12-24x+x Then just add the like terms which are the x's. 12-23x or -23x+12
