Consider a random variable Z which has a standard normal distribution (mu = 0, sigma = 1). Choose which of the following values would be equivalent to the following probability:
P (Z > 0.54)
A. P(Z > 0.54.
B. P(Z < 0.54).
C. 1 - P(Z < - 0.54).
D. 1 - P(Z < 0.54).
Answer:
A. P ( Z > 0.54) = 0,7054
B. P ( Z < 0.54) = 0.2946
C.1) 1 - 0.2946 = 0.7054
D.1) 1 - 0.2946 = 0.7054
Step-by-step explanation:
A) P ( Z > 0.54) = 1 - P ( Z ≤ 0.54)
P ( Z ≤ 0.54) = 0,2946 from z-table
P ( Z > 0.54) = 1 - 0,2946
P ( Z > 0.54) = 0,7054
B) P ( Z < 0.54) = 0.2946
C) 1 - P ( Z < - 0,54)
1 - 0.2946 = 0.7054
D) 1 - P ( Z < 0,54)
1 - 0.2946 = 0.7054

Anders throws a 10-faced dice with numbers from 1 to 10. Then he spins a coin.
b) Find the probability of scoring: i) a head and a multiple of 3 ii) a tail and a prime number
Answer:
3/20
1/5
Step-by-step explanation:
Sample space :
10 - faced die :
(1, 2, 3, 4,5, 6, 7,8, 9, 10)
Coin = (H, T)
P(H) = 1/2
Multiple of 3 = 3, 6, 9 = 3
P(Multiple of 3) = 3 / 10
P(H and multiple of 3) = 1/2 * 3/10 = 3 /20
2.)
P(tail) = 1/2
Prime numbers = (2, 3, 5, 7) = 4
P(A prime number) = 4 / 10
P(tail and prime number) = 1/2 * 4 /10 = 4 /20 = 1/5

HELP ASAP !!!!!!!!!!!!!!
Answer:
x = sqrt(17)
Step-by-step explanation:
Angle B is 90 degrees; the line BC is a radius of circle C and line AB is a tangent line of BC. Since they must be perpendicular, angle B is 90 degrees.
Now use the pythagorean theorem to solve for x.
c=9, a = 8, b= x
a^2+b^2=c^2
8^2+x^2=9^2
x=sqrt(81-64)
x=sqrt(17)

The five number summary of a dataset was found to be:
1, 5, 11, 17, 20
An observation is considered an outlier if it is below:
An observation is considered an outlier if it is above:
Answer:
Below - 13
Above 35
Step-by-step explanation:
Given the 5 number summary :
1, 5, 11, 17, 20
Minimum = 1
Q1 = 5
Q2 = 11
Q3 = 17
Maximum = 20
Lower Outlier = Q1 - 1.5*IQR
Upper Outlier = Q3 + 1.5*IQR
IQR = Q3 - Q1 = 17 - 5 = 12
LOWER = 5 - (1.5 * 12) = 5 - 18 = - 13
UPPER = 17 + (1.5 * 12) = 17 + 18= 35

PLZ HELP!!!!!!!!!!!!!!!!
Answer:
B) 119.1
Step-by-step explanation:
First, find your circle area
[tex]A=\pi r^{2} \\A=\pi 7^{2} \\A=153.9[/tex]
Then get the area of the square, we will worry about the tringles on each side in the last step.
l=12
w= 14 (Radius of circle times 2)
A=wl
A=14*12
A=168
Now the triangle
h=14 (Radius of circle times 2)
b=(27 - 12) / 2 = 7.5 ( total length 27 minus 12 divided, by 2 since there's 2 triangles on each side.
[tex]A=h\frac{b}{2} \\A=14\frac{7.5}{2} \\A=52.5[/tex]
Now add 2 triangles, the square and substract the circle
52.5+52.5+168 = 273
273 - 153.9 = 119.1 in^2

[tex]2 {a}^{2} - 3ab + {b}^{2} from3 {a}^{2} + 2ab - {b}^{2} [/tex]
Answer:
a (a - b)
Step-by-step explanation:
[tex]2a^{2}-3ab+b^{2} from 3a^{2} + 2ab - b^{2}[/tex]
Now, as [tex]2a^{2}-3ab+b^{2}[/tex] is from [tex]3a^{2} + 2ab - b^{2}[/tex]
so it will be subtracted :
[tex]3a^{2} + 2ab - b^{2}[/tex] [tex]-2a^{2}-3ab+b^{2}[/tex]
= [tex]a^{2} - ab[/tex]
= a (a - b)
) If the pattern shown continues, how many black keys appear on a portable keyboard with 49 white keys? Suggestion: use equivalent ratios or a rate table to confirm your answer.
Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
Using proportions, it is found that 35 black keys appear on a portable keyboard with 49 white keys.
This question is solved by proportions, applying a rule of three.The equivalent ratio given, from the picture, is that for 7 white keys, there are 5 black keys. Hence, how many black keys will be there when there are 49 white keys?The rule of three is:
7 white keys - 5 black keys
49 white keys - x black keys
Applying cross multiplication:
[tex]7x = 49 \times 5[/tex]
Simplifying both sides by 7:
[tex]x = 7 \times 5 = 35[/tex]
Hence, 35 black keys will appear.
A similar problem, also involving proportions, is given at https://brainly.com/question/24372153
Find the surface area of the rectangular prism
Answer:
166 in^2
Step-by-step explanation:
Formula: A=2(wl+hl+hw)
w = 4
l = 7
h = 5
wl = 4 x 7 = 28
hl = 5 x 7 = 35
hw = 5 x 4 = 20
Then we add.
28 + 35 + 20 = 83
And the multiply by 2.
83 x 2 = 166

A baker makes a circular cake that has a radius of 7 inches. If
the baker wants to cover the top of the cake with frosting, how
much frosting should the baker use?
9514 1404 393
Answer:
154 in²
Step-by-step explanation:
The area of the cake top is given by the formula for the area of a circle.
A = πr²
Here, it is convenient to use the approximation π ≈ 22/7, so we have ...
A = (22/7)(7 in)² = 154 in²
The baker should use 154 square inches of frosting for the top of the cake.
