a spinner has 3 equal sections labeled red, purple ,and yellow how many times would you expect to land on red if you doin it 24

times

Answer:

8 times

Step-by-step explanation:

we have a 1/3 chance per spin to land on red

so we would expect it to land 33.3% of the time

1/3*24=8

another easy way is to divide by 3

24/3=8

Match the following exponential functions with their "b" value.

marishachu [46]

9514 1404 393

Answer:

in order by function: 0.6, 8, 7/3, 2, 1/2

Step-by-step explanation:

The functions are given in the form ...

f(x) = a·b^x

The "b" value is the value immediately to the left of the exponent. (It's not rocket science; it's pattern matching.) Note that the minus sign in g(x) is part of 'a', not part of 'b'.

From the top-down, the functions listed on the left have the b-values shown above.

-4x+-6y=24 how do you solve?

alina1380 [7]

So,

Let's manipulate this into the y=mx + b form.

Add 4x to both sides
-6y = 4x + 24

Divide both sides by -6
$y = \frac{4}{-6} x - 4$

Just use the slope to find the points you need.

The y-intercept is (0,-4).

The slope is $\frac{4}{-6}$ . Finding the next point:
(-6,0)

You could have also used the <em>slope intercept method.</em>

-4(0) - 6y = 24
-6y = 24

Divide both sides by -6
y = -4
(0,-4)

-4x - 6(0) = 24
-4x = 24

Divide both sides by -4
x = -6
(-6,0)

Given f(x) = 2x - 2/4 the quantity of 2x minus 2 divided by 4, solve for f−1(3).

olga_2 [115]

The answer is that f-1(3) = 7.

In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.

f(x) = (2x - 2)/4 ----> Switch x and f(x)

x = (2f(x) - 2)/4 -----> Multiply both sides by 4

4x = 2f(x) - 2 ----0-> Add 2 to both sides

4x + 2 = 2f(x) ------> Divide both sides by 2

f-1(x) = (4x + 2)/2

Now that we have the inverse function, we can put in 3 and find the answer.

f-1(x) = (4x + 2)/2

f-1(3) = (4(3) + 2)/2

f-1(3) = (12 + 2)/2

f-1(3) = (14)/2

f-1(3) = 7

Information on Kwon Manufacturing’s activities for its first month of operations follows: Purchased $101,700 of raw materials on

REY [17]

1. The cost sheets for Job 201 and Job 202 are as follows:

Job 201 Job 202 Total

Direct materials $49,900 $25,300 $75,200

Direct labor 40,900 14,300 55,200

Overhead applied 39,920 20,240 60,160

Total costs $130,720 $59,840 $190,560

2. Gross profit for the sale of Job 201 = $38,140 ($168,860 - $130,720)

Data and Calculations:

Cost of raw materials purchased = $101,700

Job 201 Job 202 Total

Direct materials $49,900 $25,300 $75,200

Direct labor 40,900 14,300 55,200

Overhead applied 39,920 20,240 60,160

Total costs $130,720 $59,840 $190,560

Sales $168,860

Gross profit $38,140

Thus, the cost of Job 201 sold is $130,720 with a gross profit of $38,140.
