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.

Step-by-step explanation:
Use the compound interest formula and substitute the values given:
$250,000=P(1+0.0412)12(15)
Simplify using order of operations:

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.

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).

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
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
