three shapes. three areas to find. three areas to add together to find the whole area. gotcha.
Step-by-step explanation:
smaller rectanglelarger rectangleright trianglesmaller rectangle:
length is 7 cm and width is 4 cm, so the area is 28 square cm
larger rectangle:width is 4 cm and length is 10 cm, so the area is 40 square cm
Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.
right triangle:base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = 12 square cm
With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).
Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.
weird shape's area from adding three shapes' areas:28 + 40 + 12
= 80 square cm (ANSWER)
The population of weights for men attending a local health club is normally distributed with a mean of 172-lbs and a standard deviation of 27-lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6222-lbs. Assume that there are 34 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded
Answer:
The average weight beyond which the elevator would be considered overloaded is 183 lbs.
Step-by-step explanation:
Weight in excess of 6222 lbs means that the elevator is overload.
With 34 men:
Average weight greater than:
6222/34 = 183 lbs
The average weight beyond which the elevator would be considered overloaded is 183 lbs.

the error in lin solution is on the second line
which is 2x(4-17).it suppose to be 8x-34x.
I think this is the answer and also the mistake was that Lin forgot to add the negative symbol after solving the equation when he did 2x (4-17)
find the equation of the circle that passes through the points (0,0), (2,0)&(3,-3)
Answer:
Step-by-step explanation:
A(0,0), B(2,0), C(3,-3)

Which number is a reasonable estimate for 39x24?
Answer:
800
Step-by-step explanation:
I rounded 39 to 40 and 24 to 20 to get numbers that are eadult multiplied
then we can do 40*20 which is 800 using mental math
hope this helps <3
Answer:
1000
Step-by-step explanation:
4*2 = 8
40 * 20 = 800
4*5 = 20
40* 5 = 200
40 * 20 + 40 * 5 = 800 + 200 = 1000
40 * 25 = 1000

help i need step by step 15 points
Answer:
With what exactly can i help u with??
Answer:?
Step-by-step explanation:
Solve the equation in two different ways. Choose one method of solving in detail 5x+7(x+1) = 5x - 21
Answer:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
Step-by-step explanation:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4

1.1 = -8.5 + 6x what is x
Answer: x=1.6
Step-by-step explanation:
1.1=-8.5+6x
+8.5 +8.5 (add 8.5 on each side)
9.9=6x
Divide by 6 on each side to leave the x by itself
x=1.6
Answer:
x= 1.6
Step-by-step explanation:.
1.1=−8.5+6x
Step 1: Simplify both sides of the equation.
1.1=6x−8.5
Step 2: Flip the equation.
6x−8.5=1.1
Step 3: Add 8.5 to both sides.
6x−8.5+8.5=1.1+8.5
6x=9.6
Step 4: Divide both sides by 6.
6x /6 = 9.6/ 6
x=1.6
Answer:
x=1.6

Please help me how do I solve and draw the problem ?
Answer:
Side of the rhombus is 12 cm. Let d1 = 2x cm , so d2 = 2x+6 cm
Now, 12^2 = x^2 + (x+3)^2 = 2x^2 + 6x+9 = 144, or
2x^2 + 6x-135=0, or
x^2+3x-67.5 = 0
x1 = [-3 +(9+270)^0.5]/2
= [-3+279^0.5]/2
= [-3+16.70329309]/2 = 6.851646544 cm [x2 will be negative and so inadmissible]
So d1 = 2x6.851646544 = 13.70329309 cm and d2 = 19.70329309 cm.
So the area of the rhombus is 13.70329309x19.70329309/2 = 135 sq cm.
What is 212,514 +396,705 estimated
Answer:
Estimate = 600,000
Step-by-step explanation:
An estimate can be defined as a rough calculation of a numerical value, usually the upper limitation.
Given the following numerical values;
212,514
396,705
To add the two values together, we would first of all determine the estimate.
Estimate of 212,514 = 200,000
Estimate of 396,705 = 400,000
Adding the two values;
200,000 + 400,000 = 600,000.
Actual addition of the values would have given;
212,514 + 396,705 = 609,219.
Therefore, 600,000 is an estimated value of 609,219.
The overall regression F-statistic tests the null hypothesis that:____.
a. all slope coefficients are zero.
b. all slope coefficients and the intercept are zero.
c. the intercept in the regression and at least one, but not all, of the slope coefficients is zero.
d. the slope coefficient of the variable of interest is zero, but that the other slope coefficients are not.
Answer:
A
Step-by-step explanation:
F test is a statistical method used to determine which models best fits the population from which the sample is derived. It is a ratio of two variances. Variance measure the rate of dispersion
The formula for calculating f-test = explained variance / unexplained variance
There are two hypothesis in an f test :
1. the null hypothesis - all slope coefficient are equal to zero
the alternative hypothesis : at least one of the slope coefficient is not equal to zero
