What is z-sore ?

The z-score of a value is the count of the number of standard deviations between the value and the mean of the set. You can find it by subtracting the value from the mean and dividing the result by the standard deviation.

Here given that,

mean=[tex]69.0 inches[/tex]

standard deviation=[tex]2.8 inches[/tex]

[tex]x=-2[/tex]

The general formula of the z-score is

[tex]z=\frac{x-mean}{standard deviation}[/tex]           .......[tex](1)[/tex]

Now, putting the values in the equation [tex](1)[/tex], we get

[tex]z=\frac{-2-69.0}{2.8}\\z=\frac{71}{2.8}\\z=25.35inches[/tex]

Hence, the height of a man with a z-score is [tex]25.35inches[/tex]

$5539.53 is each withdrawal if the interest rate is 5% per year, compounded monthly.

What is compounded interest?

Compound interest is the interest earned on savings that are calculated on both the initial principal and the interest earned in previous periods.

We have,

Initial amount - le 5,00,000

Interest = l = 5/100 = 0.05/12 = 0.004167

Time period T = 25 x 12 = 300

[tex]A = P(1 + r)^t[/tex]

where A = total balance after t years,

P = principal amount (the amount invested),

r = interest rate (decimal form), and

t = time in years.

How much money will Jack have after 25 years?

m∠1 = 50°

Step-by-step explanation:

From inspection of the given diagram we can see that angle 1, angle 40° and a right angle are the interior angles of a right triangle.

As the interior angles of a triangle sum to 180°:

⇒ m∠1 + 40° + 90° = 180°

⇒ m∠1 + 130° = 180°

⇒ m∠1 + 130° - 130° = 180° - 130°

⇒ m∠1 = 50°

Therefore, the measure of angle 1 is 50°.

There are 10 multiple choice questions and 5 short response.

The following can be deduced:

The teacher gives a test with 15 questions that is worth 35 points.

The equation will be:

a + s = 15

a + 5s = 35

Subtract

The probability of event A is 5/18.

The probability of event B is 29/36.

Probability is used to determine how likely it is that a random event would happen. The probability that the random event would happen would lie between 0 and 1.

The probability that the sum is greater than 8 = sample space that have a sum greater than 8 / total number of sample space

Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

Let's x be the kenyan beans that sell for $8.25 per pound and y be venezuelan beans that sell for $9.50 per pound.

Altogether there are 50 pounds of beans.

The algebraic equation would be x + y = 18.

At $9.00 per pound, he will make 50 * $9.00 = $ 450.0

So, how many of the x and y kinds of coffee should he use to make the $9.00 per pound mixture which will net him $450.0.

The algebraic equation would be 8.25x + 9.50y = 450

We now have two equations

x + y = 50 --(i)

8.25x + 9.50y = 450 --(ii)

Substituting x= 50 - y in the second equation gives us

8.25(50-y) + 9.50y = 450

412.5 - 8.25y + 9.50y = 450

1.25y = 450 - 412.5

1.25y = 37.5

y = 30

Substitute the value of y in equation(i)

x + y = 50

x = 50 - 30

x = 20

Hence, Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

The probability that a red ticket is drawn first and then the second ticket drawn is blue is 0.253.

Probability determines the odds that a random event would occur. The odds that the random event occurs has a probability value that lies between 0 and 1.

The more likely it is that the event would occur, the closer the probability value would be to 1. The more unlikely it is that the event would not happen, the closer the probability value would be to 0.

The probability that a red ticket is drawn first and then the second ticket drawn is blue = (number of red tickets / total number of tickets) x (number of blue tickets / total number of tickets)

Total number of tickets = number of blue tickets + number of red tickets

25 + 20 = 45

The probability that a red ticket is drawn first and then the second ticket drawn is blue = (20 / 45) x (25 / 44) = 0.253

Unitary method:

The process of finding the value of a single unit, and based on this value is called as unitary method.

Given,

Out of 150 coins, 90 are quarters. Of the remaining coins, 40% are nickels and the rest are dimes and pennies. There are 5 dimes for every penny.

Here we need to find the number of pennies in the coins.

Here we know that the total number of coins are 150, thus includes

=> Quarters + nickels + dimes + pennies = 150 

Here the number of Quarters are 90 

Therefore, the remaining coins are calculated as,

=>  150 − 90 = 60

Here the percent of nickels is 40, then the number of nickels is

=> 60x 40/100

=> 24 numbers

Now, the remaining coins such as dimes and pennies are

=> 60 − 24 = 36 numbers.

Here we know that, in (5 + 1) = 6 coin of dimes and pennies there is 1 penny

Now, we will first add 14 on both sides of the above equation:

b = -10+14

We know that when two integers are of different signs then the smaller number is subtracted from the larger number but the sign in the result is of the larger number.

In the year 2018, the amount that Chase owes in federal income taxes is $16, 280.70

In 2018, Chase earned $91, 630 which put him in the 24% tax bracket. Here, his tax is $14,089.50 plus 24% of every dollar above $82,500.

The amount that Chase made above $82, 500 is:

= 91, 630 - 82, 500

= $9, 130

The federal income tax that Chase owes is therefore:

= 14, 089.50 + (9, 130 x 24%)

= 14, 089.50 + $2, 191. 20

Answer: $16,280.70

Step-by-step explanation:

First, find the difference between $91,630 and $82,500 to find the amount that is taxed at the 24% tax rate.

$91,630−$82,500=$9,130

Now, multiply $9,130 by 24% to find the additional amount of tax.

$9,130⋅24%=$2,191.20

Add $2,191.20 to $14,089.50 to find the total amount of federal income taxes Chase owes.

$2,191.20+$14,089.50=$16,280.70

Therefore, Chase owes $16,280.70 in federal income taxes for 2018.
