Answer:
9 sides
Step-by-step explanation:
Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon
Interior angle + exterior angle =
180°
Let x be the exterior angle.
Exterior angle = 180-x = 100 + x
= 180 - 100 = x + x
80 = 2x
x = 80/2
x = 40
Number of sides of the polygon =
= 360°/Exterior angle
Exterior angle = 40°
= 360/40 = 9 sides
can someone help me with a few of these?
Answer:
can you please tell us which ones?
Step-by-step explanation:
12. a²+b²=c²
7²+b²= 8²
49+b²=64
b²=64-49
b²= 15
Sq root both sides
b or well X=3.87
13. 4²+x²=8²
16+ײ=64
ײ=48
Sq root both sides
x=6.93
1.) Phoebe has a hunch that older students at her high school are more likely to bring
a bag lunch than younger students, because they have grown tired of cafeteria
food. she takes a simple random sample of 80 sophomores and finds that 52 of
them bring a bag lunch. a simple random sample of 104 seniors reveals that 78 of
them bring a bag lunch. Does this data provide convincing evidence to support
Pheobe's hunch at the 5% significant level?
2.)Interpret the P-value in context
The data in this experiment is not convincing enough to prove the hypothesis.
What is convincing evidence?In an experiment, convincing evidence means the data collected is relevant and accurate enough to prove the hypothesis. For the data to be considered convincing it should:
Prove the hypothesis: This condition is satisfied because the data collected can prove older students are more likely to bring a bag lunch.Be collected using random samples: This condition is satisfied because students were selected randomly.Consider the standard or norma: This condition is met because the research compares the number of sophomore students that bring a bag lunch vs the number of seniors.7Moreover, the P-value should be always smaller than the significant level. In the case of this study, the P-value is 0.069, which means it is greater than the significant level 0.05 and this causes the data is not convincing enough.

27.5 = CE
Step-by-step explanation:
The two triangles should be similar to each other, so we can set up a ratio of 15:6. This gives us a final ratio of 2.5:1 Multiply EA = 11 by 2.5 to find its corresponding side measure
11*2.5 = 27.5

Answer:
1) $575
2) They'll markup the price by $3,240. After the markup, the retail price is $15,240
Step-by-step explanation:
1)
6% = 0.06
3750(0.06) = 225
225 + 350 = 575
2)
27% = 0.27
12000(0.27) = 3240
Profit = 3240
Price for retailer = Cost Price + Profit
Price for retailer = 12000 + 3240
Price for retailer = 15,240

Bridget drew ΔYZ and Δ′ ′ ′ on a coordinate plane, as shown below.
Which statement about the relationship between ΔYZ and Δ′ ′ ′ is true?
A: Δ′ ′ ′ is NOT a translation of ΔXYZ because not all points contained in Δ′ ′ ′ have negative x-coordinates.
B: Δ′ ′ ′ is a translation of ΔXYZ because their corresponding sides are parallel.
C: Δ′ ′ ′ is a translation of ΔXYZ because all points in Δ′ ′ ′ are the same distance and direction from the corresponding points in ΔXYZ.
D: Δ′ ′ ′ is NOT a translation of ΔXYZ because the y-coordinate of Point is not the same as the y-coordinate of point ′.
Answer:
The statement that is true about the relationship between ΔXYZ and ΔX'Y'Z' is option "C"
C. ΔX'Y'Z' is a translation of ΔXYZ because all points in ΔX'Y'Z' are the same distance and direction from the corresponding points in ΔXYZ
Step-by-step explanation:
The triangles Bridget drew are;
ΔXYZ and ΔX'Y'Z'
The coordinates of ΔXYZ = X(-5, 7), Y(-9, 2), Z(-3, 2)
The coordinates of ΔX'Y'Z' = X'(1, 2), Y'(-3, -3), Z'(3, -3)
From the coordinates we have;
The x-coordinates of ΔX'Y'Z' = The x-coordinates of ΔXYZ + 6
The y-coordinates of ΔX'Y'Z' = The y-coordinates of ΔXYZ - 5
Therefore, the translation that gives ΔX'Y'Z' from ΔXYZ = T₆, ₋₅
Therefore;
1) ΔX'Y'Z' is obtained from ΔXYZ by a translation as the points in ΔX'Y'Z' are obtained from ΔXYZ by adding the same value to the x-coordinates of the points on ΔXYZ and subtracting the same value to the y-coordinates of the points on ΔXYZ, such that the points in triangle ΔX'Y'Z' are equidistant from and on the same side relative to the corresponding points on ΔXYZ
2) Given that triangle ΔXYZ and ΔX'Y'Z' are not rotated or reflected, we have that the corresponding sides of ΔXYZ and ΔX'Y'Z' are parallel
The correct options are therefore option "C" and and the option "B" is only partially correct because the sides can be parallel but do not have the same size.

Answer:
60 in³
Step-by-step explanation:
In a triangle
Area of the triangle
= 1/2 * base * height
= 1/2 * 4 * 3
= 6 in²
Height of the prism = 10 in
Volume of the prism
= Area of base * height
= 6 * 10
= 60 in³

What is the Mode? 21,28.27.26.27.27.33.28.26.31
Answer:
The mode is 27.
Step-by-step explanation:
To find the mode we must first put them in order from least to greatest.
21, 26, 26, 27, 27, 27, 28, 28, 31, 33
The mode means the most common number out of the data. Therefore since 27 is the most common number, it is the mode.
Hey there!
The mode is basically the number you see MORE THAN ONCE.
So, the numbers in your data plot is/are
“21, 28, 27, 26, 27, 27, 33, 28, 26, 31”
(I’m assuming)
21 is shown ONE TIME
28 is shown TWO TIMES
27 is shown THREE TIMES
26 is shown TWO TIMES
33 is shown ONE TIME
31 is shown ONE TIME
THE BIGGEST ONE THAT’S SHOWN IS: 27 because it was shown in your data plot three times
Answer: 27
