Answer:
a lot less because 0.4 is not fully of 100%
Step-by-step explanation:
Answer:
52 is 0.4% of 130. You would expect the number to be a lot greater than 52
Step-by-step explanation:
If the number we are trying to find is x, we have to use the equation x*0.4=52 which can be rewritten as 52/0.4=x
If you solve that, you get 130.
The number is expected to be a lot greater than 52 because 0.4 is almost 0.5 and that would mean doubling 52 so the number would be almost double 52. That means it would be a lot greater.
A computer routine selects one of the integers 1, 2, 3, 4, 5 at random and replicates the process a total of 100 times. Let S denote the sum of the 100 numbers selected. Calculate the approximate probability that S assumes a value between 280 and 320 inclusive.
Probability that S assumes a value between 280 and 320 inclusive is 0.853.
S = Σ[tex]X_{i}[/tex] where [tex]X_{i}[/tex] has a uniform distribution on 1, 2, 3, 4, 5, with mean 3 and variance (25 – 1)/12 = 2 (result known, or calculated via E[[tex]X^{2}[/tex]] = 11, or from book of formulae, p10, with a = 1, b = 5, h = 1).
So S ~ N(300, 200) approximately.
P(280 ≤ S ≤ 320) = [tex]P(\frac{279.5-300}{\sqrt{200} } < Z < \frac{320.5-300}{\sqrt{200} })[/tex]
= [tex]P(-1.450 < Z < 1.450)[/tex]
= 0.853.
Hence, probability is 0.853.

Answer:
y=8 x=-19.5
Step-by-step explanation:
Start from the bottom equation and work your way upSolve the fourth equation for w-5w=-15-5w/(-5)=-15/(-5)w = 3 Then use that value of w to plug into the third equation. Notice we're going backwards or up the chain of equations. After w is replaced, solve for zz+w = 2z+3 = 2z+3-3 = 2-3z = -1 Now use z = -1 and w = 3 to plug into the second equation. Solve for y-2y-12z-4w = -16-2y-12(-1)-4(3) = -16-2y+12-12 = -16-2y = -16-2y/(-2) = -16/(-2)y = 8

How much money, to the nearest penny, will Marissa have in 7 years?
Give your answer in dollars.
Marissa will have $720 in 7 years when she has $48 in her saving account that earns 2% simple interest per year.
What is simple interest?Simple interest is a quick and simple approach to figuring out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of many forms of interest that banks charge. Now, let's first clarify what a loan is before delving further into the idea of simple interest.S.I. = P R T,where
P = Principal, R = Rate of Interest in% per annum, and T = Time periodThe interest rate is expressed as r/100 and is expressed as a percentage or r%.Principal: The principal is the sum that was first invested or borrowed from the bank. P stands for the principal.Rate: Rate is the interest rate at which the principal sum is granted to someone for a specific period of time; examples of rate interest are 5%, 10%, and 13%. R stands for the interest rate.Time: The amount of time that the principal is given to someone. T represents time.Amount: When a borrower repays a bank loan, the term "Amount" refers to the sum of the principal borrowed plus the interest paid.Amount = Principal + Simple Interest or A = P(1 + RT)Calculation
From, A = P(1 + RT)
where, p = $48
R = 2%
T= 7 years
A = 48(1 + 2*7)
A = $720
Hence, Marissa will have $720 in her bank account after 7 years.

Answer: x = -135.59
Step-by-step explanation:
20 = 0.694(x + 150)(2)
Step 1: Simplify both sides of the equation.
20 = 0.694 (x + 150)(2)
20 = 1.388x + 208.2 (use the distributive property)
20 = 1.388x + 208.2
Step 2: Flip the equation.
1.388x + 208.2 = 20
Step 3: Subtract 208.2 from both sides of the equation.
1.388x + 208.2 − 208.2 = 20 − 208.2
1.388x = −188.2
Step 4: Divide both sides by 1.388.
