Answer:
50%
Step-by-step explanation:
The distribution is symmetrical about the y-axis.
The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.
What is Probability?The branch which deals with the occurrence of a random event is known as probability.
The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero
As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.
In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.
Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Help!! Solve 1 1/4 + 5 5/6
Answer:
7 2/24
Step-by-step explanation:
We can start by making the denominators the same (the bottom number)
1 1/4+5 5/6
1 6/24+ 5 20/24=7 2/24
Answer:
so what you would want to do is get your fraction into improper fractions and to do that you multiply the whole number by the denominator and add it to your numerator, once you do that you get 5/4, and 35/6, now we want to get common denominators, so we multiply 5/4, by 6/6, and 35/6 by 4/4 which would get us 30/24 and 140/24 then we add them and get 170/24 and then simplify, which gets you 85/12 and then put it into a mixed number which is 7 1/12

Simplify; (³√729)³ + 24
Answer:
[tex](\sqrt[3]{729} )^{3}[/tex] + 24 can be simplified to 753.
Step-by-step explanation:
If you take the root of a number to a specific number, then square that by the same number you took the root by, then you will have the same number you started with. In this case, [tex]\sqrt[3]{729}[/tex] equals 9, and [tex]9^{3}[/tex] equals 729, so [tex](\sqrt[3]{729} )^{3}[/tex] equals 729. 729 + 24 = 753, so that is the simplified answer.

help please. If (a,b) is the center of this circle, fine a+b
Answer:
Given
(X+1)²+(y+4)² =25
or, {x-(-1)}² +{y-(-4)}² =5²
comparing with (x-h)²+(y-k)² = r²
h= -1
k= -4
center of circle (h,k)= (-1,-4)
by question..
(a,b) is centre of circle so...
(a,b) =(-1,-4)
i.e
a=-1
b=-4
now;
a+b= -1+(-4)
= -1-4

Fantasy 5 lottery game is picking 5 numbers from 1-41. If you match them all you win the jackpot. What is the probability you win the jackpot?
Answer:
1 / 89927760
Step-by-step explanation:
Recall :
Probability = required outcome / Total possible outcomes
To pick five number for a lottery from the range (1 - 41) ;
For this scenario, selection will be done without replacement
To win lottery , all 5 selections must be matched
P(1st pick) = 1 / 41
P(2nd pick) = 1 /40
P(3rd pick) = 1/39
P(4th pick) = 1/38
P(5th pick) = 1/37
(1/41 * 1/40 * 1/39 * 1/38 * 1/37) = 1 / 89927760
Hence, Probability of winning lottery = 1 / 89927760

The circumference of a circle is about 50 centimeters (cm). Which is closest to the length of its radius? You may use 3.14 for
Α.4 cm
B. 8 cm
C.16 cm
D.32 cm
Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.

A factory manufactures 9 x 10^5 packs of gum each month. They send these out to 16 different distribution centers. If each distribution center gets the same number of packs, how many are sent to each center?
Answer:
The answer would be A.
Step-by-step explanation:
You would take 9 x 10^5 = 900000 and divide that by 16 to get 56250.
After that, you move the decimal over by 4 to make it a number with only one number above zero in front of the decimal to make 5.625 (negate the 0 bc it does not mean anything after you moved the decimal over)
Since you moved it over by four places, the exponent next to the 10 will be 4, making the final answer 5.625 x 10^4
Good luck and hope this helps!!
John is placing cement tiles for a patio in a rectangle surrounding a
rectangular fire pit. The fire pit has a width of x ft and a length that is 4
times the width. The entire patio is 9 ft wider and 13 ft longer than the fire
pit. What is the area that he will need to buy tiles for?
Answer:
31x + 55 sq. ft.
Step-by-step explanation:
Width of Fire Pit = x ft. Length of Fire Pit = 4x ft.
Width of Patio = x + 5 ft. Length of Patio = 4x + 11 ft. Area of Fire pit = 4x * x = 4x² sq, ft.
Total Area of Rectangular Patio (including Fire pit) = (4x + 11)(x+5)
= 4x² + 31x + 55 sq. ft.
Area for which tiling is done = Area of Rectangular patio - Area of fire pit
= 4x² + 31x + 55 - 4x²
= 31x + 55 sq. ft.
2x - 5 + ¾ (4x - 8) =19

Answer:
41
Step-by-step explanation:
Usando BODMAS, entonces que tenemos
(2 + 4 * 3) =
(2 + 12) =
14
Con el segundo uno, tenemos
(3 * 2 - 2 * 2). Con esto, dices que
(3 * 2) - (2 * 2) =
6 - 4 =
2
Y ahora, decimos que
3 * (14) - 2(2) + 5 - 2 =
42 - 4 + 3 =
42 - 1 = 41
