Write the equation of the line in slope-intercept that has passes through the points (-8,-11) and (10,-2).
Answers
Answer:
y = 0.5x-7
Step-by-step explanation:
First we need to find the slope so we use the formula y2 - y1 / x2 - x1 = m
The variable m will represent the slope or rate of change
-2 - (-11) / 10 - (-8) = m
Or
-2 + 11 / 10+8 = m
9/18 = m
0.5 = m
y = 0.5x+b
To find b replace the y and x variables
I will use 10 and -2
-2 = 0.5(10)+b
You should come out with -7 = b
The heights of adult men are normally distributed with a mean of 69 inches and a standard deviation of 2.75 inches. What percentile does a man who is 72 inches fall?
Answers
Answer:
86.2%
Step-by-step explanation:
Given that:
Mean, m = 69 inches
Standard deviation. s = 2.75
Man who is 72 inches tall ; x = 72
Using the relation :
Zscore = (x - mean ) / standard deviation
Zscore = (72 - 69) / 2.75
Zscore = 3 / 2.75 = 1.09
Z = 1.09
P(Z < 1.09) = 0.862 (Z probability calculator)
0.862 * 100% = 86.2%

what is the median of the following 9 numbers 23,15,32,27,19,22
Answers
22.5 i think but i have no idea good luck
The median of the following 9 numbers 23,15,32,27,19,22 is 22.5.
What is median?The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data point. to find the median firstly arrange the data points in ascending order.
Arrange the data points from smallest to largest;
15, 19, 22, 23, 27, 32.
Total number of data points is 6. And 6 is the even number.
So median of even numbers of data points is average of two middle points.
And those numbers are 22 and 23.
Average of 22 and 23 is (22 + 23) / 2 = 22.5
Therefore the median is 22.5.

Write the equation for this graph in the form y=mx+b
Answers
Answer: y = 2x + 50
Step-by-step explanation:
first find the slope (m):
slope = rise/run = y1-y2/x1-x2
(1,52); (2,54)
slope = (54-52)/(2-1) = 2/1 = 2; m = 2
now since we have the slope and a point, we will put it into point-slope form:
y = m(x - x1) + y1
y = 2(x - 3) + 56
y = 2x - 6 + 56
y = 2x + 50

if triangle abc is similar to triangle edc find the value of x
Answers
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{BC}{DC}[/tex] = [tex]\frac{AC}{EC}[/tex] , substitute values
[tex]\frac{3x-5}{32}[/tex] = [tex]\frac{5x-5}{56}[/tex] ( cross- multiply )
56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides
168x - 280 = 160x - 160 ( subtract 160x from both sides )
8x - 280 = - 160 ( add 280 to both sides )
8x = 120 ( divide both sides by 8 )
x = 15

The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?
Answers
Answer:
3 hours
Step-by-step explanation:
Number of shows : Time taken
= 4 : 2
Today, they will perform 6 shows.
Number of shows : Time taken
= 6 : x
Equate both ratios to find x
4 : 2 = 6 : x
4/2 = 6/x
Cross product
4 * x = 2 * 6
4x = 12
x = 12/4

One day Akash walked 2/3 km from home to school .On his return he took another route which was 3/5 km long .How many km did Akash walk in all?
please answer in steps.
Answers
Answer:
Akash walked [tex]1\frac{4}{15}[/tex] kilometers in all.
Step-by-step explanation:
Given that:
Distance covered while walking to school = 2/3 km
Distance covered while walking back = 3/5 km
We will add the distance.
Total distance walked = [tex]\frac{2}{3}+\frac{3}{5}[/tex]
Total distance walked = [tex]\frac{10+9}{15}[/tex]
Total distance walked = [tex]\frac{19}{15}=1\frac{4}{15}\ km[/tex]
Hence,
Akash walked [tex]1\frac{4}{15}[/tex] kilometers in all.

What is Unitary Method?Unitary method is a technique used in mathematics to solve problems that involve proportional relationships. It involves finding a unit rate (i.e., a rate per unit) and using it to solve problems that involve different quantities of the same type of unit.
To find the amount of time Ana spent working, we need to subtract the starting time from the finishing time.
The starting time is 2:45 pm and the finishing time is 5:30 pm.
We can subtract the starting time from the finishing time as follows:
