Answer:
17 square units
Step-by-step explanation:
There are several ways you can divide this figure into areas that are easily computed.
One that comes to mind is to consider the triangle that would include the missing area at lower right. That triangle would have a base of 6 and a height of 8, so an area of ...
A = (1/2)bh
A = (1/2)(6)(8) = 24 . . . . square units
The part at lower right that is cut out is a sort of reversed L-shape that is 3 squares along the bottom and 4 more up the side, for a total of 7 squares.
Then the area of the shaded part is ...
A = 24 - 7 = 17 . . . . square units

Step-by-step explanation:
Given
The attachment
Required
State the reason for the given statements
m = n
m and n are corresponding angles.
So:
[tex]m = n[/tex]
x = y
x and y are vertically opposite angles
So:
[tex]x = y[/tex]
[tex]y + n = x + m[/tex]
In (b)
[tex]x = y[/tex]
Add m to both sides
[tex]x + m = y +m[/tex]
In (a) [tex]m = n[/tex]
So, substitute n for m on the left hand side
[tex]x + n = y + m[/tex]

62.8 If rounded to the nearest hundredth it is 62.80
Step-by-step explanation:
1. Formula for circumference of a cirlcle is 2 (pi) r where for this problem,
2 =2,
pi= 3.14 and
r= 10 (1/2 of the diameter =radius)
2. 2 x 3.14 x 10
multiply all 3 numbers above, you get 62.8
3. Depending on your teacher or the test,
62.8 is your answer, if it HAS to be to the nearest hunderedth, and it's on a specific program, it might want you to enter the "0" at the end 62.80

.4^3Grafting, the uniting of the stem of one plant with the stem or root of another, is widely used commercially to grow the stem of one variety that produces fine fruit on the root system of another variety. Suppose grafts are done one at a time. A graft fails with probability 0.4, independently of the others. Given there were no failed grafts in the first seven done, what is the probability that there will be at least one failed graft in the next three done
Answers
Answer:
0.784 = 78.4% probability that there will be at least one failed graft in the next three done
Step-by-step explanation:
To solve this question, we need to understand the binomial probability distribution and conditional probability.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: No failed grafts in the first seven
Event B: At least one fail in the next three.
Intersection of events A and B:
Since the probability of a graft failling is independent of other grafts, we have that:
[tex]P(A \cap B) = P(A)*P(B)[/tex]
So
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)*P(B)}{P(A)} = P(B)[/tex]
So we just have to find the probability of one fail in three trials.
Three trials means that [tex]n = 3[/tex].
The probability is
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{3,0}.(0.4)^{0}.(0.6)^{3} = 0.216[/tex]
Then
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.216 = 0.784[/tex]
0.784 = 78.4% probability that there will be at least one failed graft in the next three done

Liz and her two friends went out to lunch. Their bill came out to be $21.75. If they split the cost equally, how much does each girl owe?
SHOW YOUR WORK
Answers
This being because if you start with $21.75 you have to divide that by 3, because you have 3 people splitting the bill.
Another way to do this is by dividing .75 by three (which we know 75 divided by 3 equals 25 so the .75 divided by 3 equals .25. Then we know 21 divided by 3 is 7. So then you would just add 7 + .25 together and get $7.25!

I need help. Alina drew a model of a square pyramid. The dimensions of the model are shown in the diagram. What is the volume of Alina’s model in cubic centimeters. Does anyone know what it means? I don’t get it.
Answers
Answer:
400 cm
I found the answer on Quizizz lol, I had the same question for a review :/ I still don't know how they got the answer though
The volume of Alina’s model in cubic centimeters when the side is 10 so here the volume should be considered as the 400.
Calculation of the volume:Since
The Height of the pyramid is 12 cm
The area of the base should be
[tex]= side^2\\\\= 10^2\\\\= 100[/tex]
Now the volume be
[tex]=1/3 * 100 * 12[/tex]
= 400
Hence, The volume of Alina’s model in cubic centimeters should be 400.

Christian was 145 cm tall when he was 12 years old. And 3 years later, he became 168.2 cm tall. By what percent did Christian's height increase?
Answers
Answer: 16%
Step-by-step explanation:
168.2 - 145 = 23.2
23.2/145 = 0.16
0.16 as a percent is 16%
The percentage change of the height is A = 16 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Christian's height increased by
168.2 - 145 = 23.2 cm
To find the percentage increase, we need to divide the increase by the original height and then multiply by 100:
Percentage increase = (23.2 / 145) x 100%
Percentage increase = 0.16 x 100%
Percentage increase = 16%
Hence , Christian's height increased by 16%

In rectangle ABCD, diagonals and AC BD intersect at E. If AC= 4x + 8 and BE = x + 2, then the length of diagonal AC is ____ ?
Answers
Answer:
AC = 8
Step-by-step explanation:
AC = 4x + 8
BE = x + 2
x + 2 = x + 2
2x = 2 - 2
2x = 0
2x\2 = 0/2
x = 0
AC = 4x + 8
AC = 4(0) + 8
AC = 0 + 8
AC = 8
When the AC= 4x + 8 and BE = x + 2, so the length of diagonal AC is to be considered as the 8.
Calculation of the length of diagonal AC:
Since
AC = 4x + 8
BE = x + 2
Now
x + 2 = x + 2
2x = 2 - 2
2x = 0
x = 0
Now
AC = 4x + 8
AC = 4(0) + 8
AC = 0 + 8
AC = 8
hence, the length of diagonal AC is to be considered as the 8.
