Find the probability that Mary cannot work the problem.

HELP PLEASE!!!

Answers

Answer:

the answer is 30% hope this helps you

Answer:

30%

Step-by-step explanation:

The two outcomes (can work the problem and can't work the problem) are complementary.

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.

Complementary events are two outcomes of an event that are the only two possible outcomes.

Complementary outcomes add to 1 or 100%.

100 - 70 = 30.

What is the equation of this line?

y=34x−3

y=−3x−34

y=−3x−43

y=43x−3

Answers

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3

Write your answer as a fraction in simplest form.

Answers

Answer:

6/7 is your answer

Step-by-step explanation:

10+2+2 is 14 and that's your total number of cards. then you add the blue cards and the yellow cards to get your answer and reduce.

12/14 = 6/7

there are fourteen cards in total so that’s your denominator.
12 of the 14 cards are not red
12/14 simplify

A total of $8000 is invested: part at 5% and the remainder at 13%. How much is invested at each rate if the annual interest is $730?

Answers

Answer:

$3875 at 5%

$4125 at 13%

Step-by-step explanation:

Let x = amount invested at 5%.

Let y = amount invested at 13%.

x + y = 8000

0.05x + 0.13y = 730

Solve the first equation for x and sustitute into the second one to solve by the substitution method.

x = 8000 - y

0.05(8000 - y) + 0.13y = 730

400 - 0.05y + 0.13y = 730

0.08y = 330

y = 4125

x = 8000 - 4125

x = 3875

Answer:

$3875 at 5%

$4125 at 13%

Answers

The 75 exhibits are in the reptile house.

we have given that,

A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.

We have to determine how many exhibits are in the reptile house.

Therefore we have

if 15 exhibits = 20% of total exhibits,

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100.

then 15/20% = 75 total exhibits in the reptile house

We can check the answer,

75 x 20% = 15

Therefore the 75 exhibits are in the reptile house.

After two semesters of course work, a student has completed 32 credit hours of course work with a grade point average of 3.15. What grade point average will the
student need to complete in order to raise their cumulative grade point average to 3.2, if the student is taking 14 credit hours of graded course work this semester
(third semester)?

Answers

Using weighed average, it is found that the student will need a GPA of 3.31.

To find a weighed average, each value is multiplied by it's weight.

For the student's average, we have that:

GPA of 3.15 with a weight of 32.GPA of x with a weight of 14.

We want the mean to be 3.2, thus:

[tex]\frac{3.15(32) + 14x}{32 + 14} = 3.2[/tex]

[tex]3.15(32) + 14x = 46(3.2)[/tex]

[tex]14x = 46(3.2) - 32(3.15)[/tex]

[tex]14x = 46.4[/tex]

[tex]x = \frac{46.4}{14}[/tex]

[tex]x = 3.31[/tex]

The student will need a GPA of 3.31.

1/2

Answers

Step-by-step explanation:

the slope of a line is the ratio y/x.

that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.

so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).

therefore, the slope is

15/30 = 1/2

If I`m going to solve "what is the percent is 29.00 out of of 122.50 what do I multiply by 100 or 122.50?

Answers

Answer:

I don't know the answer you know

What percent is 29 out of 122.50 is the same as, “29% of 122.50”

All you need to do is to convert 29% to decimal by moving the decimal point 2 places to the left = 0.29.

Next, multiply 0.29 by 122.50:

0.29 × 122.50 = 35.525 or 35.53 (or 36 if rounded to the nearest ones or whole number).
