Input 0 for x, because the y-intercept is on the y-axis.

G(0) = 3(0) - 2

Simplify.

G(0) = -2

The answer is A, (0, -2)

Martha has $20 to spend on a t-shirt. She has a coupon for 20% off. The t-shirt regularly sells for $22.50 plus 10% sales tax.

rodikova [14]

Answer:

1 and 3

Step-by-step explanation:

Step 1 is clearly elaborated. Tax is impliedd on the discounted price.

In step 3, the steps of deductions are skipped.

Like 1 + 10% = 110% and 1 - 20% = 80%

Step 2 is simply wrong. Because the percentages are implied on different values.

Help for a friend? They don't have an account so I am asking for them. Please answer fast!

sveta [45]

Answer:

A. 7*5 + 4^2 - 2^3 / 4 = 35 + 16 - 8 / 4 = 35 + 16 - 2 = 49

B. The statement of seven times five plus four squared minus 2 cubed divided by 4 is equal to 49. (or whatever your friend's teacher wants when they ask for a complete sentence).

C. PEMDAS - parentheses, exponents, multiplication, division, addition, subtraction

Note:

When remembering PEMDAS, please remember that multiplication actually isn't prioritized over division - they should be performed "simultaneously" from left to right. Same with addition and subtraction. The order is: P -> E -> MD -> AS.

Associations In Data:Question 10

Karo-lina-s [1.5K]

Answer:

$\bar X = \frac{62+63+68+72+79+80+83+93+94+95}{10}= 78.9$

$|62-78.9| = 16.9$

$|63-78.9| = 15.9$

$|68-78.9| = 10.9$

$|72-78.9| = 6.9$

$|79-78.9| = 0.1$

$|80-78.9| = 1.1$

$|83-78.9| = 4.1$

$|93-78.9| = 14.1$

$|94-78.9| = 15.1$

$|95-78.9| = 16.1$

$MAD = \frac{\sum_{i=1}^n |X_i -\bar X|}{n}$

And replacing we got:

$MAD =\frac{16.9+15.9+10.9+6.9+0.1+1.1+4.1+14.1+15.1+16.1}{10}= 10.12$

And the best anwer is

10.12

Step-by-step explanation:

We have the following data given:

62 63 68 72 79 80 83 93 94 95

And we need to begin finding the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = \frac{62+63+68+72+79+80+83+93+94+95}{10}= 78.9$

Now we can find the mean absolute deviation like this:

$|62-78.9| = 16.9$

$|63-78.9| = 15.9$

$|68-78.9| = 10.9$

$|72-78.9| = 6.9$

$|79-78.9| = 0.1$

$|80-78.9| = 1.1$

$|83-78.9| = 4.1$

$|93-78.9| = 14.1$

$|94-78.9| = 15.1$

$|95-78.9| = 16.1$

And finally we can find the mean abslute deviation with the following formula:

$MAD = \frac{\sum_{i=1}^n |X_i -\bar X|}{n}$

And replacing we got:

$MAD =\frac{16.9+15.9+10.9+6.9+0.1+1.1+4.1+14.1+15.1+16.1}{10}= 10.12$

And the best anwer is

10.12

Write a system of equations using x and y in each for the following

vlada-n [284]

1) x+y = 170
x-y = 26

2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.

x-28 = 26
x = 54

3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
