Answer: 0.4016
Step-by-step explanation:
Let x be a random variable that represents the height of women in a country.
Mean : [tex]\mu=64.3[/tex] inches
Sample size : n= 65
Standard deviation: [tex]\sigma=2.81[/tex]
The probability that the mean height for the sample is greater than 65 inches = [tex]P(x>65)=1-P(x<65)[/tex]
[tex]=1-P(\dfrac{x-\mu}{\sigma}<\dfrac{65-64.3}{2.81})\\\\= 1-P(z<0.2491)\\\\=1-0.5984\ \ \ \text{[By p-value table]}\\\\=0.4016[/tex]
Hence, the probability that the mean height for the sample is greater than 65 inches = 0.4016
what are the factors of x^2-8x-20
Answer:
(x+2)(x−10)
Step-by-step explanation:
x^2-8x-20
Factoring means something like this:
(x+_)(x+_)
Add together to get -8
Multiply together to get -20
think of the two numbers
Try 2 and -10:
2+-10 = -8
2*-10 = -20
Fill in the blanks of with 2 and -10 to get
(x+_)(x+_) = (x+2)(x−10)
I hope it's right!
0.5 kilograms is equal to how many grams
Answer:
500 grams.
Step-by-step explanation:
1kg = 1000grams.
0.5 * 1000 = 500grams.
Answer:
500 grams
Step-by-step explanation:
Because 1000grams = 1kg so 100 = 0.1
So to get this you multiply 0.5 with 1000

Pretend a classmate missed the lesson today. What would you tell them about how to make a table to represent a rate? How would you tell them how to use the table to make a graph?
Answer:
In order to make a table representing a rate, you would have to find the unit rate of what you need. Then you would take it and multiply it by the multiple, or divide it by the factor needed.
Step-by-step explanation: Example
Unit rate=1:2
Make multiples and input into graph(the colons represent the graph)

Calculate the area of a triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2). A. 14 square units b. 15 square units c. 18 square units d. 20 square units
Answer:
15
Step-by-step explanation:
took the test
The area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.
What is a triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle ABC with altitude CD.
The coordinates for the triangle are A (-3, -4), B (-6, 2), C (0, 0), and
D (-4, -2)
From the figure, the distance between C and D will be the height of the triangle:
We can calculate the distance between the points by using the distance formula:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
h = √20
b = √45
Area of triangle = (1/2)bh = (1/2)√20×√45
= (1/2)30
= 15 square units
Thus, the area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.

Answer:
18.6cm (rounded to 3 s.f.)
Step-by-step explanation:
You can actually figure out the two bases of the triangles based on the Pythagoras theorem where the slant length of a 90° triangle is [tex]\sqrt{a^{2} + b^{2} }[/tex] where a is one of the bases and b is the other length that is 90° perpendicular to a.
So this means:
[tex]\sqrt{6^{2} + base^{2} }[/tex] = 8cm
6² + base² = 64cm
36 + base² = 64
base² = 64-36
= 28
base = [tex]\sqrt{28}[/tex]
≈ 5.2915 (5 s.f.)
So the two bases are roughly 5.2915, and the middle base is part of a rectangle, so it has the same length as the rectangle's length, which is 8cm.
Thus, x = 5.2915 + 5.2915 + 8
= 18.6cm (rounded to 3 s.f.)

Answer:
The trip is 50 miles long
Step-by-step explanation:

6 Bridesmaids want to make 330 decorations for a wedding. Each
decoration takes about 2 4 minutes to make. How many hours will it take
for each person to make all the decorations?
Answer:
about 3.21 hours each
Step-by-step explanation:
First divide 330 by 6 since there are six people.
Every person needs to do 55 decorations.
I would take the average of 2-4 minutes and multiply it by 55.
55 x 3.5 = 192.5 minutes
to convert to hours divide by 60.
192.5 / 60 = 3.21
