slope = 5

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = 5(x - 4) ← is in point- slope form

with slope m = 5

8 times 2/3 is 16/3, which when simplified is 5 1/3

To evaluate 8(2/3), you need to multiply 8 by 2/3. The value of 8(2/3) is 16/3.

To evaluate 8(2/3), you need to multiply 8 by 2/3. To do this, you can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1.

This simplifies 2/3 to 2/3. Then, multiply 8 by 2/3 to get the final answer.

Therefore, the value of 8(2/3) is 16/3.

Given the point (9,2) is on the graph of f(x), the corresponding point for the function f(-3/4x) is found by multiplying the x-coordinate of the given point by -3/4. This yields the corresponding point (-6.75, 2).

The given point is (9,2). In the function f(-3/4x), the variable is multiplied by the factor -3/4. We apply this factor to the x-coordinate of the given point to find the x-coordinate of the corresponding point in the function f(-3/4x).

Therefore, the x-coordinate of the corresponding point is 9×-3/4 = -27/4 = -6.75. The y-coordinate remains the same because the transformation corresponds only to the x-coordinates of points. So, the corresponding point in the function f(-3/4x) is (-6.75,2).

64.5x = 7500 → x ≈ 116.3

Subtract 100 from the new percent (116.3 − 100 = 16.3) → 16%

The approximate percentage of the tip is 14%.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Dinner at your favorite restaurant cost $64.50 with tax for you and your family.

You give the waiter $75 to pay the bill and a tip.

That means,

the tip amount = 75 - 64.50

= 10.50

The tip percentage,

= 10.50 x 100 / 75

= 14%

Therefore, 14% is the required percentage.

Answer:

[tex]\frac{901}{999}[/tex]

Step-by-step explanation:

we know that

A Recurring Decimal, is a decimal number with a digit (or group of digits) that repeats forever.

In this problem we have

0.901 recurring

that means

0.901901901..

Let

[tex]x=0.901901901..[/tex]

Multiply x by a power of  [tex]10[/tex], one that keeps the decimal part of the number the same:  

[tex]1,000x=901.901901..[/tex]

Subtract [tex]x[/tex] from [tex]\\1000x[/tex]

[tex]1,000x-x=901.901901..-0.901901..=901[/tex]

The repeating decimals should cancel out

[tex]\\999x=901[/tex]

Step-by-step explanation:

Answer:

Option B. skewed left.

Step-by-step explanation:

In the figure attached maximum frequency of the data is at the 45. Distribution on the right side of the maximum frequency is upto 48 and in the left it is upto 36.

As we can see point 36 is more distant from peak point 45 as compared to point 48.

Therefore, distribution of the data is more in the left than in the right.

Therefore, the shape of this distribution is skewed left.

Option B. skewed left is the correct answer.

Step-by-step explanation:

We know that 15/20 students voted in the StuCo election on the first go around.

Using this ratio for 16 student is as simple as multiplying 15/20 by 16

(15/20)*16=12

Based on the voting ratio of 3:4 from Monday's election, we predict that 12 out of the 16 students present on Tuesday voted.

The question asks to predict the number of students who voted in Tuesday's election based on the ratio of students who voted on Monday. On Monday, 15 out of 20 students voted, which establishes a voting ratio of 15:20, or 3:4 when simplified. To predict Tuesday's voter turnout, we apply this ratio to the 16 students present on Tuesday.

Using the simplified ratio of 3:4, for every 4 students, 3 vote. Since 16 students were in class on Tuesday:

Therefore, we predict that 12 students voted in Tuesday's election.

Answer:

2541 peanut cookies were sold

Step-by-step explanation:

A system of equations can be written to match the problem description. Let p and c represent the initial numbers of peanut and chocolate cookies, respectively. Then we have ...

p - c = 1820 . . . . Lyn had 1820 more peanut cookies

After selling 35% of her peanut cookies, Lyn had 1-0.35 = 0.65 of the original number left. Likewise, after selling 15% of her chocolate cookies, she had 1-0.15 = 0.85 of the original number left. Then after the sales, the difference in cookie count was 95:

0.65p -0.85c = 95

We only need to know the original number of peanut cookies (p), so we can use Cramer's rule to find the solution for p.

p = (-95 +0.85·1820)/(-0.65+0.85) = 1452/0.20 = 7260

The original number of peanut cookies Lyn had was 7260, so the number she sold is ...

0.35 · 7260 = 2541

_____

Cramer's rule says the solution to ...

ax +by =c

dx +ey =f

is given by ...

x = (ec-bf)/(ea-bd)

y = (fa-cd)/(ea-bd)
