Answer:
0.749
Step-by-step explanation:
We start by calculating the z-score
Mathematically:
z-score = (x-mean)/SD
z-score = (75-77)/3 = -2/3 = -0.67
The probability we want to calculate is;
P( X > -0.67)
we can use the standard normal distribution table for this
Using this table, the probability has a value 0.74857 which is 0.749 to the nearest thousandth

Gray started the week with $150 in his checking account. The chart shows the credits and charges to his account during the week.
Credit Charge
$20 $52
$23 $16
$14 $28
How much money did Gray have in his account at the end of the week?
O $3
O $111
$189
$303
Answer:
111
Step-by-step explanation:
150 + 20 = 170
170 - 52 = 118
118 + 23 = 141
141 - 16 = 125
125 + 14 = 139
139 - 28 = 111

If an item has an original price of $80 and has been discounted 20%, what is the sale price?
Answer:
$64
Step-by-step explanation:
Since 20% is 0.20 and a whole is 1.00, to discount the price, we have to subtract the whole value by the discount value 1.00-0.20=0.80
Then we have to find 80% of 80
80%=0.80
0.80*80=64
The sale price is $64

y = 5х – 4
QUICK! how do i do this i need the x and y this is the Systems of equations with substitution
Answer:
x=1/15 y = -4 1/3
Step-by-step explanation:
First combine like terms.
-3y = 13
y= -13/3
y= -4 1/3
Substitute for y in next equation
-4 1/3 = 5x - 4
5x = 4 1/3 - 4
5x = 4 1/3 - 4
5x = 1/3
x = 1/3 divided by 5
Since fractions can't be divided, multiply by the inverse
x = 1/3 times 1/5 = 1/15

Find the slope of a line with the given points
Answer:
C) 0
Step-by-step explanation:
Hi there!
We are given these two points: (11, -10), and (-16, -10)
We want to find the slope of these two points
The formula for the slope (m) calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have 2 points, but let's label their values to avoid any confusion.
[tex]x_1=11\\y_1=-10\\x_2=-16\\y_2=-10[/tex]
Now substitute these points into the formula (remember: the formula has SUBTRACTION)
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-10--10}{-16-11}[/tex]
simplify
m=[tex]\frac{-10+10}{-16-11}[/tex]
m=[tex]\frac{0}{-27}[/tex]
divide
m=0
The answer is 0, which is option C.
Hope this helps!

simplify this expression: 5 + 2b - 2
Answer:
3 + 2b
Step-by-step explanation:
To simplify, you have to combine (add) like terms. The like terms are 5 and -2 because they both do not have a variable.
5 + (-2) = 3
2b stays the same because there are no like terms for it.
3 + 2b

Kiran has 10 1/2 feet of lumber and wants to make a bookshelfKiran needs two side panels that are each 5 2/3 feet. How much more lumber does Kiran need in order to make the side panels?
Total height of lumber, H = 10 1/2 feet = 21/2 feet .
Height of side panel, h = 5 2/3 feet = 17/3 feet .
Now,
Extra lumber required, L = 2 × Height of side panel - Total height of lumber
[tex]L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet[/tex]
Therefore, extra lumber required is [tex]\dfrac{5}{6}[/tex] feet.
Hence, this is the required solution.

two fair dice are rolled. the score is the difference between the two dice. some of the possible scores are shown in the table.
c) which score has a probability of occurring 1/18
Answer:
Step-by-step explanation:
a). From the table attached,
Number in 1st column and 1st row = 1 - 1 = 0
Number in 1st column and 6th row = 6 - 1 = 5
Number in 2nd column and 4th row = 4 - 2 = 2
Number in 5th column and 2nd row = 5 - 2 = 3
Number in 6th column and 5th row = 6 - 5 = 1
b). Probability of scoring 1 = [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]
Preferred outcomes of getting = 10
Total outcomes = 36
Probability of scoring 1 = [tex]\frac{10}{36}[/tex]
= [tex]\frac{5}{18}[/tex]
c). Probability of occurring a score = [tex]\frac{1}{18}[/tex]
= [tex]\frac{1\times 2}{18\times 2}[/tex]
= [tex]\frac{2}{36}[/tex]
= [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]
Since, 5 is a number which has occurred twice
Score that has a probability of occurring of [tex]\frac{1}{18}[/tex] is 5.
