Complete question :
The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 20.8 years; the
standard deviation is 3.1 years.
Use the empirical rule (68 – 95 - 99.7%) to estimate the probability of a gorilla living less than 23.9 years.
Answer:
84%
Step-by-step explanation:
Given :
Mean, m = 20.8
Standard deviation, s = 3.1 ; x = 23.9
The Zscore = (x - mean) / standard deviation
P(x < 23.9) = (23.9 - 20.8) / 3.1 = 1
P(x < 23.9) = 1
P(Z < 1) = 0.84134
0.84134 * 100% = 84.13%
= 84%

Answer: D
Explanation: You add 5x2 and 2x2 giving 7x2. You then add 3x and 6x but because there is 2x2-6x you actually would just leave it as is (In this instance). Then add 4 and 3 giving you 7. Therefore, The answer is 7x2-3x+7

Amy mows lawns to earn money for a new phone. She charges $8.15 an hour. How much money will she earn if she mows for 4.5 hours? Show your work for full credit.
Answer:
every hour is $8.15 if 4.5hours her mows is $33.15
Answer:
$36.68
Step-by-step explanation:
If she mows for 4.5 hours, you multiply that by how much she makes an hour. each hour she makes $8.15 each hour.
4.5 * 8.15= 36.675

Submit Answer
Answers:
For original triangle, perimeter is 60. The area is 120.
The dilated triangle, perimeter is 180. The area is 1080.
Step-by-step explanation:
24 times 3=72
10 times 3=30
26 times 3=78
72+30+78=180
Perimeter of diliated triangle
1/2btimesh=area
1/2 30 times 72=1080 square units
Perimeter of original triangle
24+10+26=60 units
1/2 10 times 24=120 square units
From the picture attached,
Measure of the base of the small right triangle = 10 units
Height of the triangle = 24 units
Measure of the Hypotenuse = 26 units
Since, Perimeter of the triangle = Sum of the measures of the sides of the triangle
Therefore, Perimeter = 10 + 24 + 26
= 60 units
Area of the triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(10)(24)[/tex]
= 120 units²
Given triangle is dilated by a scale factor of 3 to form the bigger triangle,
Scale factor = 3
Since, expression for the scale factor is given by,
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]
Therefore, length of the base of the dilated (bigger) triangle will be,
[tex]3=\frac{\text{Measure of the base of the original}}{10}[/tex]
Measure of the base of the original = 30 units
Height of the dilated triangle will be,
[tex]3=\frac{\text{Height of the dilated triangle}}{24}[/tex]
Height = 24 × 3
= 72 cm
Hypotenuse of the dilated triangle will be,
[tex]3=\frac{\text{Hypotenuse of the dilated triangle}}{26}[/tex]
Hypotenuse = 78 cm
Now the perimeter of the dilated triangle = 30 + 72 + 78
= 180 cm
Area of the dilated triangle = [tex]\frac{1}{2}(30)(72)[/tex]
= 1080 cm²

5,6,7, and 8
Answer:
Step-by-step explanation:
General form of circle: (x - h)² + (y- k)² = r²
r - > radius and h ,k are the coordinates of the center.
5) (x - 5)² + (y- 1)² = 64 = 8²
radius: 8 ; Center (5 , 1)
6) (x + 7)² + (y- 2k)² = 324 = 18²
Center = ( -7 , 2) ; radius = 18 ; diameter = 18 *2 = 36
7) (x )² + (y + 10)² = 42.25 = 6.5²
Center = (0 , - 10); radius = 6.5 ; diameter = 6.5*2 = 13
8) (x - 6)² + (y + 1)² = 80 = (4√5)²
Center =(6, -1) ; radius = 4√5
Question 14. When solving the equation -14 = 7x + 6 what will the next stage of your working be?
Answer:
You would subtract 6 from each side.
Step-by-step explanation:
- 14 = 7x + 6
Subtract 6 from each side:
- 14 - 6 = 7x + 6 - 6
7x = - 20
Divide each side by 7:
7x ÷ 7 = - 20 ÷ 7
x = 2 and 6/7

∠A and ∠B are vertical angles. If m∠A=(5x+5)∘and m∠B=(4x+29)∘, then find the measure of ∠A.
Answer:
∠A = 175∘
Step-by-step explanation:
∠A = ∠B
5x-5= 4x+29
x = 34
∠A= 34*5+5
∠A=170+5=175
5x+5= 4x + 29

5x=4x+24
-4x -4x
x=24
m∠A=5x+5
m∠A=5(24)+5

joe wants to make a scale drawing of a flower for mrs Samuelson.she wants him to use a scale of 2 cm:5in. If the flower is 8 in height in real life, how high should he make his drawing?
The required scale is 2 cm t 5 in
This means that 2cm on the drawing would represent 5 inches on the actual flower. If the flower is 8 inches in real life, then the equation would be as shown below
2cm = 5 in
xcm = 8 in
where x represent the height of the flower on the drawing. By cross multiplying, we have
x * 5 = 2 * 8
5x = 16
x = 16/5
x = 3.2
The height of the tree on the drawing would be 3.2 cm
The needed scale is 2 cm:5in
It means that 2 cm will represent 5 inch of actual flower. if the flower of 8 inch would be in real the required equation would be:
2cm = 5 inch
xcm= 8 inch
X representing height of flower.
After Cross Multiplying,
2 × 8 = x × 5
[tex]x = \frac{2 \times 8}{5} \\ \\ x = \frac{16}{5} \\ \\ x = 3.2[/tex]
The Height Of the tree required is 3.2 cm
Hope This Helps You ❤️What number is 25% of 5/8?
(( Can someone please give the formula, this is like reading a foreign language to me lol ))
Thank you.
A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.
Now multiply the two.
0.25x5/8.
We need to convert 5/8 to a decimal, which is 0.625.
0.25x0.625=0.15625.
Now convert the decimal to a fraction, which is 5/32.
