Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.

The temperature in an oven changes from 350 degrees to 362 degree. What is the percent increase in temperature, to the nearest tenth of a percent?
Answers
Answer:
3.4%
Step-by-step explanation:
Find the percent increase by dividing the difference in the temperatures by the original temperature, then multiplying it by 100:
((362 - 350) / 350) x 100
(12 / 350) x 100
= approximately 3.4
So, the percent increase in temperature was approximately 3.4%

Step-by-step explanation:

Answers
Answer:
m∠A = 120°
m∠C = 45°
Step-by-step explanation:
all triangle angles add up to 180
(12x + 12) + 15 + (3x +18) = 180
15x + 45 = 180
15x = 135
x = 9
m∠A = (12x + 12) = 12(9) + 12 = 120
m∠C = (3x +18) = 3(9) + 18 = 45
WHAT IS THE PERIMETER OF THE TRIANGLE
GET THIS RIGHT AND YOU GET 100 POINTS
Answers
Answer:
40
Step-by-step explanation:
SO im guessing if its the full graph one box counts 1.
So the top side counts 8
The left one is 15
The perimeter means adding all the sides together.
We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.
a^2+b^2=c^2
8^2+15^2 = c^2
64+225 = c^2
289 = c^2
c = 17
so the perimeter is 8+15+17 = 40

their average age?
A. 14 B. 13
C. 12 D. 11
Answers
Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13

The stem-and-leaf plot shows the numbers of hours 10 students studied for their math exam. Find the mean, median, mode, range, and interquartile range of the data
Answers
The question is incomplete as the stem and leaf plot required to to provide data for y question isn't given.
In other to help with this question, I have attached a stem and leaf plot with 10 data values and I will be calculating the required statistical measures for the dataset. The knowledge can thus be applied to solve similar questions on your exact data set.
Answer:
Kindly check explanation
Step-by-step explanation:
Firstly, we need to write out values if the dataset :
Each value in the dataset is a combination of the stem and the corresponding leaf or leaves.
For the stem plot attached :
Dataset , X : 08, 12, 17, 18, 19, 22, 23, 31, 35, 40
The mean :
Σx / n
n = sample size = 10
= 225 / 10
= 22.5
Arranging data on ascending order :
08, 12, 17, 18, 19, 22, 23, 31, 35, 40
The median :
1/2(n+1)th term
1/2(11)th term = 5.5 th term = (5+6)th term / 2
Median = (19+22)/2 = 20.5
Mode = all dataset (since they all occur once).
Range = (maximum - minimum) = 40 - 8 = 32
Interquartile range : (Q3 - Q1)
Q3 = 3/4(n+1)th term ; 3/4(11) = 8.25th term
Q3 = (8th + 9th) term / 2 = (31+35)/2 = 33
Q1 = 1/4(n+1)th term ; 1/4(11)th term = 2.75 th term
Q1 = (12+17)/2 = 14.5
Interquartile range : (Q3 - Q1) = 33 - 14.5 = 18.5
Answer:
Median: 11
Mode: 3
Range: 30

Answer:
x = 2
x < 2
x < 3
Step-by-step explanation:
2x + 5 = 9
Since there is an addition sign in front of 5, you must do the opposite: subtraction. Subtract 5 from 9.
9 - 5 = 4.
Lastly, divide the difference by the number in front of x (2).
2x = 4
4 ÷ 2 = 2
x = 2
--------------------------------------------------------------------------------------------------------------
2x + 5 < 9
Again, subtract 5 from 9.
9 - 5 = 4
Lastly, divide the difference by the number in front of the x (2).
2x = 4
4 ÷ 2 = 2
x < 2
--------------------------------------------------------------------------------------------------------------
4x - 5 < 7
Since there is a subtraction sign in front of the 5, you must do the opposite: addition. Add 5 to 7.
5 + 7 = 12
Lastly, divide the sum by the number in front of the x (4).
4x = 12.
12 ÷ 4 = 3
x < 3
