Answer: The perimeter is 20 cm
Step-by-step explanation: The top and bottom are same length, so 6+6, and the sides are the same length, so 4+4 don’t forget it’s cm and it becomes 20 cm.
PERIMITER = ADDING ALL SIDES
AREA = MULTIPLYING

solve the inequality 3/5x +30>150
Answers
Answer:
Step-by-step explanation:
3/5x+30=150
We move all terms to the left:
3/5x+30-(150)=0
Domain of the equation: 5x!=0
x!=0/5
x!=0
x∈R
We add all the numbers together, and all the variables
3/5x-120=0
We multiply all the terms by the denominator
-120*5x+3=0
Wy multiply elements
-600x+3=0
We move all terms containing x to the left, all other terms to the right
-600x=-3
x=-3/-600
x=1/200

What are population and sample?It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.
We have:
Survey data involving two random samples of students at law school are shown. The surveys were taken, comparing the age of students in 1900 to the age of students in 2014.
The statements that are true about the two samples of students:
In 1990, there was a 10-year age difference between the oldest and youngest students.In 2014, the median age of students was greater than the median age in 1990.Thus, statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

What is the area of the figure composed of a parallelogram, a square, and a rectangle?
Answers
Answer:
Let's cut the figure into:
Parallelogram, square, and rectangle.
Let's find the area of the parallelogram first:
10 x 3.5 = 35
Let's find the area of the square:
4 x 4 = 16
When given one length of a square you already know are sides and lengths are equal so therefore 1 given length of a square is all the lengths.
Let's find the area of a rectangle:
6 x 12.5 = 75
Now let's add all the areas up:
35 + 16 + 75 = 126 square inches is your answer.

find f(3) for the polynomial function F(x)=x^3-9x^2+5x-2
Answers
Answer:
f(3) = -41
Step-by-step explanation:
f(x) = x³-9x²+5x-2
now,
f(3) = 3³-9×(3)²+5×3-2
= 27-9×9+5×3-2
= 27-81+15-2
= -41
A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. He subdivided a portion of his land into 10 separate, but essentially equal, plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Below is a computer output for linear regression of amount of fertilizer versus yield for the 10 plots of land.
Predictor Coef SE Coef T P
Constant 10.100 0.7973 12.67 0.000

What is the equation of the least squares regression line from this sample?
Answers
Answer:
Y = 10.1 + 1.50x
Step-by-step explanation:
From the data contained in the computer output for linear regression
The coefficient of intercept = 10.1
coefficient of fertilizer = 1.50
Sample of an Equation of least squares regression line
y = a + bx
where : a = intercept , b = slope
hence the required equation will be
Y = 10.1 + 1.50x
y = yield , x = fertilizer
Which of the following is the correct point-slope equation for the line that
passes through the point (-3,-9) and is parallel to the line given by
y = 2.5x - 20?
O A. Y-3 = 2.5(x-9)
B. y + 3 = 2.5(x + 9)
O C. y + 9 = 2.5(x + 3)
O D. Y- 9 = 2.5(x-3)

It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet. A transportation researcher wants to determine if the statement made in the advertisement is false. She randomly test drives 36 small cars at 65 miles per hour and records the braking distance. The sample average braking distance is computed as 114 feet. Assume that the population standard deviation is 22 feet. Use Table 1. State the null and the alternative hypotheses for the test. H_0:mu = 120: H_A: mu notequalto 120 H_0:mu 2 greaterthanorequalto 120: H_A mu < 120 H_0: mu lessthanorequalto 120: H_A: mu > 120 Calculate the value of the test statistic and the p-value. {Negative values should be indicated by a minus sign. Round "Test statistic" to 2 decimal places 3nd "p-value" to 4 decimal places.} The p-value is: p-value < 0.01 0.01 lessthanorequalto p-value < 0.025 0.025 lessthanorequalto p-value < 0.05 0.05 lessthanorequalto p-value < 0/.10 p-value greaterthanorequalto 0.10 c. Use alpha = 0.01 to determine if the average breaking distance differs from 120 feet. Repeat the test with the critical value approach. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.)
Answers
Answer:
H0: mu = 120 , Ha: : mu not equal to 120
The p-value is greater than or equal to 0.10
z= -1.636
Since the calculated value of z does not fall in the critical region H0 is not rejected.
Step-by-step explanation:
State the null and alternate hypothesis
H0: mu = 120
average braking distance for a small car traveling at 65 miles per hour equals 120 feet.
against the claim
Ha: : mu not equal to 120
average braking distance for a small car traveling at 65 miles per hour does not equal 120 feet.
The p-value equals 0.101764 which is greater than 0.01 and thus supports H0.
The p-value is greater than or equal to 0.10
The test statistic z is applied
Here
Sample Mean x~ = 114
Population mean μ =120
Sample size n= 36
Population SD =σ= 22
Z= u- μ/σ√n
Z= 114- 120/ 22/ √36
z= -1.636
This is a two tailed test and the critical region for two tailed test at alpha = 0.01 is z ∝/2= ± 2.58
Since the calculated value of z does not fall in the critical region H0 is not rejected.
