<h2>Let's solve for x ~ </h2>

\qquad \sf  \dashrightarrow \: 2x - 13 = 9

\qquad \sf  \dashrightarrow \: 2x =  9 +13

\qquad \sf  \dashrightarrow \: 2x = 22

\qquad \sf  \dashrightarrow \: x = 22 \div 2

\qquad \sf  \dashrightarrow \: x = 11

x = 11

2x = 13 + 9

2x = 22 |: 2

Merry Soy, married, earns a weekly salary of $830 and claims one withholding allowance. By the percentage method, how much incom
xxMikexx [17]
You need to find the amount subject to withholding, subtracting from the weekly salary the amount for one withholding allowance for weekly salaries, which is 77.90$:

830 - 77.90 = 752.1 $.

Then, look in the Fed Tax tables (
http://www.opers.ok.gov/Websites/opers/images/pdfs/2016-Fed-Tax-Tables.pdf ) for a married person with a weekly payroll.

You previously found an amount of  752.1 which is greater than 521 but less than 1613$: therefore the income tax to withhold is 35.70$ + 15% of excess over $521.

Therefore, calculate the income tax due: 35.70 + (752.1 - 521) × 15 ÷ 100 = 70.37$

The total amount of income tax that will be withheld is 70.37$

The random variable X, representing the number of accidents in a certain intersection in a week, has the following probability d
ollegr [7]

Answer: 0.70

Step-by-step explanation:

Given : The random variable X, representing the number of accidents in a certain intersection in a week, has the following probability distribution:

       x       0       1         2        3       4       5

P(X = x) 0.20   0.30   0.20   0.15   0.10  0.05

Using the above probability distribution , the  the probability that in a given week there will be at most 3 accidents is given by :_

P(\leq3)=P(0)+P(1)+P(2)+P(3)\\\\=0.20+0.30+0.20=0.70

Hence, the required probability = 0.70

Which could be a conditional relative frequency table ???
user100 [1]

Answer:

The table that represents the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0

Step-by-step explanation:

We know that a conditional relative frequency table is one:

In which the entries in each row is divided by the row total .

                        OR

In which the entries in each column is divided by the column total.

i.e. the frequency or quantity of an item is being compared either to row or to the column total.

Hence, from the given options, the table that represent the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0

One number is 3 more than another number. if you add 12 to 4 times the first number, the result is 5 times the second number. Fi
aleksklad [387]

Answer:

first is -3, second number is 0

Step-by-step explanation:

you have two equations x+3=y and 4*x+12=5*y

Use the first one and write y in terms of x in the second equation:

4*x+12=5*(x+3)

4*x+12=5*x+15

12=5*x-4*x+15

12=x+15

x=-3
