Answer:
Erin
Step-by-step explanation:
Z score formula:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Candice:
Z score = 74 -66/4
Z score = 2
For Erin
Z score = 58 - 42/7
Z score = 2.28571
Erin z score is larger hence, he did better

$120 less than half of d dollars
Answer:
[tex]\frac{d}{2} - 120[/tex]
Step-by-step explanation:
You work backwards:
Half of d dollars is d/2. Then you take 120 less than that, which means you are subtracting.
Answer:
1/2d-120
Step-by-step explanation:
Alright.
d=amount of money
1/2d=half of the amount of money
1/2d-120=half of the money minus 120

Mr. Carson makes $21.50 an hour. He works 8 hours a day and works 5 days a week.
Answer:
$860
Step-by-step explanation:
21.50 times 8 = 172
172 times 5 = 860
CallmeCarson lol
Answer:
860$
Step-by-step explanation:
In order to find the answer to this question you need to multiply the amount of hours Carson worked to the amount of days he worked and then you need to multiply that by the amount he gets paid per hour.
[tex]21.50 = ph[/tex]
[tex]hours=8[/tex]
[tex]days = 5[/tex]
[tex]8\times5=40[/tex]
So he worked 40 hours a week
[tex]40 \times21.50 = 860[/tex]
Therefore Mr.Carson has made 860$ that week.
Hope this helps.
A bag contains two coins, one for which the probability of heads is equal to 1 and one for which the probability of heads is equal to p. A coin is selected at random, and three independent tosses of this coin result in three heads. What is the probability that a further independent toss of this coin will produce a head?a. p4/1 + p3.b. p3 - p2/1 + p3.c. p3/1 - p.d. 1/1 + p3.e. 1 + p4/1 + p3.
Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)
Step-by-step explanation:
P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)
= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)
therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))
= 1 / (1 + p³)
Also P( second coin given 3 heads) = p³ /(1 + p³)
therefore P(4th toss in heads given first 3 are heads) will be;
= P(first and 4th toss heads) + P(second and 4th toss heads)
=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p
= (1 + p⁴) / (1 + p³)
Therefore Option E is the correct answer
There are two people in Sophia's class of 25 named Michael. She infers that 8% of people in the U.S. are named Michael. What is
wrong with Sophia's conclusion?
A)Nothing is wrong with Sophia's conclusion. 2/25=0.08, which is 8%.

could someone please help me with #2? Thank you :)
Answer:
The answer is B.
Step-by-step explanation:
4 is a multiple of 2, which explains the reasoning of answer choice B.
Answer choice A is wrong because 2 is Not a multiple of 4.
Answer choices C and D are incorrect because it takes multiple steps to solve for x and substitute into the other equation. They claim that it takes on step to solve for x, but it would take 2 steps to solve for x.

which expression is equivalent to 40x^2 square root x^12 ÷ 10^2 square root 29x^8, if x does not equal 0?
The expression that is equivalent to the given expression is 10(2x)².
Equivalent expressionThe equivalent expression is obtained by simplifying the given expression as shown below;
40x², where, x ≠ 0
expand the expression as follows;
40x² = (10 x 4)x²
= (10 x 2²)x²
= 10(2²x²)
= 10(2x)²
Thus, the expression that is equivalent to the given expression is 10(2x)².

Connor works in a department store selling clothing. He makes a guaranteed salary of $300 per week, but is paid a commission on top of his base salary equal to 5% of his total sales for the week. How much would Connor make in a week in which he made $2175 in sales? How much would Connor make in a week if he made xx dollars in sales?
Earnings when selling $2175:??
Earnings when selling $x: ??
Answer:
[tex]Earnings = 308.75[/tex] ---- (a)
[tex]Earnings = 300 + 0.05x[/tex] -- (b)
Step-by-step explanation:
Given
[tex]Base\ Salary = 300[/tex]
[tex]Commission = 5\%[/tex]
Solving (a): Sales of $2175 in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * 2175[/tex]
[tex]Earnings = 300 + 108.75[/tex]
[tex]Earnings = 308.75[/tex]
Solving (b): Sales of $x in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * x[/tex]
Convert percent to decimal
[tex]Earnings = 300 + 0.05 * x[/tex]
[tex]Earnings = 300 + 0.05x[/tex]

Sandy has around $245 in her pocket but she thinks she could have up to $25 more or $25 less. Write and solve an absolute value equation that can show the maximum and minimum amount of money that Sandy has in her pocket.
Answer:
The absolute value equation is |x - 245| = 25The maximum amount of money in Sandy's pocket is $270The minimum amount of money in Sandy's pocket is $215Step-by-step explanation:
The absolute value equation for the amount of money in Sandy's pocket is given as;
|x - 245| = 25
The equation for the maximum amount of money in Sandy's pocket is given as;
x - 245 = 25
x = 25 + 245
x = $270
The equation for the minimum amount of money in Sandy's pocket is given as;
x - 245 = -25
x = -25 + 245
x = $215
