Answer:
$390 you divide 520 by 4 so 520/4=130 now we subtract 130 from 520, 520-130=390
Step-by-step explanation:
Solving this question requires basic arithmetic formula and fractions.
New weekly income = $390
Let's call the number of hours kim works weekly as "x"
If she reduces this number of hours by one-fourth and her current weekly income is $520, then it means the amount to be deducted is;
[tex]\frac{1}{4}[/tex] × $520 = $130
Thus, her new weekly income will be;
$520 - $130 = $390

find the value ofx in the equation 3x+1=×+9.
Answer:
x = 4
Step-by-step explanation:
First, you subtract 1 from both sides, giving you 3x = x + 8
Then you subtract 1x from both sides, so 2x = 8
Divide the 2 from both sides which leaves you with the answer, x = 4
Nicole invested $400 in a fund for 6 years and was paid simple interest. The total interest that she received on the investment was $72. As a
percentage, what was the annual interest rate of her investment?
Answer:
83.3333%
Step-by-step explanation:
The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:
A = P + I = P + (Prt), and finally A = P(1 + rt)
Is it geometric or arithmetic? Why
Answer: It is Geometric.
Step-by-step explanation: Because it does not have a fixed pattern that adds or subtract which arithmetic does.
10. According to a survey, about 58% of families sit down for a fumily dinner at least four times per week. You ask 5 randomly chosen families whether they have a family dinner at least four times per week.
a. Draw a histogram of the binomial distribution for the survey.
b. What is the most likely outcome of the survey?
c. What is the probability that at least 3 families have a family dinner four times per week?
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Given n = 5, p = 0.58, and q = 0.42.
P(0) = ₅C₀ (0.58)⁰ (0.42)⁵⁻⁰ = 0.013
P(1) = ₅C₁ (0.58)¹ (0.42)⁵⁻¹ = 0.090
P(2) = ₅C₂ (0.58)² (0.42)⁵⁻² = 0.249
P(3) = ₅C₃ (0.58)³ (0.42)⁵⁻³ = 0.344
P(4) = ₅C₄ (0.58)⁴ (0.42)⁵⁻⁴ = 0.238
P(5) = ₅C₅ (0.58)⁵ (0.42)⁵⁻⁵ = 0.066
The most likely result is 3 families.
The probability of at least 3 families is:
0.344 + 0.238 + 0.066 = 0.648

the negative sign= - is meaning below so
12 below is -12 which is less so 8 is greater
What came first into your mind when you read the word “union"? How did you
get the union between the two given sets?
Answer:
well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets
Determine the mean, median, mode, and midrange for this collection of class test scores: 88 82 97 76 79 92 65 84 79 90 75 82 78 77 93 88 95 73 69 89 93 78 60 95 88 72 80 94 88 74 a. Mean is 84, median is 82, mode is 82, midrange is 77 b. Mean is 82, median is 88, mode is 88, midrange is 77 c. Mean is 82.4, median is 88, mode is 82, midrange is 78.5 d. Mean is 82.4, median is 82, mode is 88, midrange is 78.5
Mean of a given set of data = Sum of all observations ÷ Total number of observations
Mean of this data set = 88 + 82 + 97 + 76 + 79 + 92 + 65 + 84 + 79 + 90 + 75 + 82 + 78 + 77 + 93 + 88 + 95 + 73 + 69 89 + 93 + 78 + 60 + 95 + 88 + 72 + 80 + 94 + 88 + 74
Mean = 2729 ÷ 30
Mean = 82.4Median = the middle observation in a given set of data
Median of these test scores = 60 , 65 , 69 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 78 , 79 , 79 , 80 , 82 , 82 , 84 , 88 , 88 , 88 , 88 , 89 , 90 , 92 , 93 , 93 , 94 , 95 , 95 , 97 .
Median = 82 + 82 / 2
= 164 ÷ 2
= 82
Median = 82Mode = most frequently occurring number in a given set of data .
Mode of these test scores =
= 60 = 1 time
= 65 = 1 time
= 69 = 1 time
= 72 = 1 time
= 73 = 1 time
= 74 = 1 time
= 75 = 1 time
= 76 = 1 time
= 77 = 1 time
= 78 = 2 times
= 79 = 2 times
= 80 = 1 time
= 82 = 2 times
= 84 = 1 time
= 88 = 4 times
= 89 = 1 time
= 90 = 1 time
= 92 = 1 time
= 93 = 2 times
= 94 = 1 time
= 95 = 2 times
= 97 = 1 time
Mode = 88Midrange = average of the largest and smallest number in a given set of data
Midrange of these test scores = 97 + 60 / 2
= 97 + 60 / 2
= 157 ÷ 2
= 78.5
Midrange = 78.5Therefore , the correct option is :-
(d) Mean is 82.4 , median is 82 , mode is 88 , midrange is 78.5An orthocenter of a triangle is

What is the slope of the line that passes through:
(6,5) and (-1,-4)
Thank You!
Answer:
[tex]m=\frac{9}{7}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-4-5}{-1-6}[/tex]
[tex]m=\frac{-9}{-7}[/tex]
[tex]m=\frac{9}{7}[/tex]

What would be the answer to number nine
Answer:
x=9.06
Step-by-step explanation:
We have the hypotenuse and we want the opposite of angle a.
so we do
sin65 = x/10.
Solve for x by simplifying both sides of the equation, then isolating the variable.
2) Why is it that when you fill the venn diagram with the number of elements, you
always need to start from the intersection of all sets?
Answer:
This is because it is easier this way.
You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".
This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.

Find the area of the triangle. 13 m 16 m
Answer:
Area = 104
Step-by-step explanation:
The equation to find the area of a triangle is A = 1/2 BH
so if we plug in to numbers into the equation we get
A = 1/2 13*16 no we can multi plier 13*16 and we get 208
and last we can multiply 1/2 to 208 and our final answer is 104
