Complete the equation of the line whose y-intercept is (0,6) and slope is 3​

Answer:

8/13

Step-by-step explanation:

In a standard deck there are 52 cards. Let A denote the event of drawing a black card and B denote the event of drawing face card. We have to find P(A or B) or P(A∪B).

P(A∪B)=P(A)+P(B)-P(A∩B)

There are 26 black cards in a standard deck so,

P(A)=26/52.

There are 12 face cards in a standard deck so,

P(B)=12/52.

There are 6 cards that are black face cards.

P(A∩B)=6/52.

P(A∪B)=P(A)+P(B)-P(A∩B)

P(A∪B)=26/52+12/52-6/52

P(A∪B)=38/52-6/52

P(A∪B)=32/52

P(A∪B)=8/13

Thus, probability of drawing a black card or a face card is 8/13.

Answer:

2.088

Step-by-step explanation:

Trust me I am in high school honors algebra with almost an average of 100.

The product of 2.4 x 0.87 is 2.088.

A decimal is represented by a dot which separates the whole part and the fractional part of a number.

According to the given question we have to multiply two decimals numbers  2.4 and 0.87.

Multiplication of decimals numbers can be easily done just by removing the decimas and multiplying them in form of integers and after obtained result we'll put the decimal as many digits before from the rightmost side as the sum of the digits which those two numbers have after the decimal.

So, (24×87) = 2088 now the sum if the digits is 3 so we'll put the decimal 3 places before which is 2.088.

Answer:

A=750 +75*t

B=900 +25*t

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.

Step-by-step explanation:

You know that High School A currently has 750 students  and is projected to grow by 75 students each year.   With A being the number of students in High School A in t years, this number will be the number of students it has initially added to the number of students who have joined after t years. This is represented by:

A=750 +75*t

You know that High School B currently has 900 students  and is projected to grow by 25 students each year.   With B being the number of students in High School B in t years, this number will be the number of students it has initially added to the number of students who have joined after t years. This is represented by:

B=900 +25*t

You want to determine how many students there would be in each high school in the year that they are projected to have the same number of students. That is, in year t the number of students is the same, so

A = B

750 +75*t=900 + 25*t

Solving:

75*t -25*t= 900 - 750

50*t= 150

[tex]t=\frac{150}{50}[/tex]

t=3

This indicates that in year 3 both High Schools are projected to have the same number of students. To get that amount, you simply replace this value in the expressions:

A=750 +75*t= 750 +75*3= 975

B=900 + 25*t=900 + 25*3= 975

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.

Answer:

0.3264

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where

x is the raw score,

μ is the population mean,

σ is the population standard deviation.

(x-μ) = 3.6 mm

σ = √variance = √64 = 8mm

z = 3.6/8

z = 0.45

Using the Probability table

P(x<Z) = 0.67364

P(x>Z) = 1 - P(x<Z)

1 - 0.67364

= 0.32636

Approximately = 0.3264

Bachelor's degree salary = $53000

Master's degree salary = $66000

Step-by-step explanation:

Given that :

Let Salary of bachelor's degree holder = x

Salary of Master's degree holder = 2x - 40000

Master's salary + bachelor's salary = $119,000

Hence,

Master's salary + bachelor's salary = 119,000

2x - 40000 + x = 119,000

3x = 119000 + 40000

3x = 159000

x = 159000 / 3

x = $53,000

Bachelor's degree salary = $53,000

Master's degree salary ; 2x - 40000 ; 2(53000) - 40000 = $106,000 - $40,000 = $66000

Answer:

his percent grade was 80

Step-by-step explanation:

15 is 20 percent of 75

This is a proportion problem. Eric earned 60 out of a possible 75 points, so the ratio is 60/75. You put that equal to x, so 60=x% and 75=100%. So it would look like

60 = x

75 100

then you cross multiply 60 and 100, and 75 and x, so you get

6000=75x

then divide by 75 and you have your percent

You change a fraction into a percentage by multiplying by 100.

So, for example, half is 1/2. Multiply by 100 gives 100/2=50. So half is 50%.

The percentage increase for flight tickets to fly from orlando to hartford would be = 67.5% and 92.5% when there is an additional $50 to the new price.

Percentage increase is defined as the rise in the quantity or amount for an object which is converted into percentage.

The formula for percentage increase would be = increase ÷ original amount × 100

The increase of the cost = 335 - 200 = $135

The original amount = $200

The percentage increase = 135/200 × 100

= 13500/200 = 67.5%

But if the increase in cost is 135 + 50 = $185

The percentage increase of the new cost would be;

= 185/200 ×100

= 18500/200

= 92.5%

The question is wrong bro.

Answer:

Question 1: She had $352 in her wallet

Question 2: The percent of the trout were the tiger trout is 45%

Step-by-step explanation:

Question 1:

∵ Carmen spent $88 at the mall

∵  The money she spent was 25% of the total amount she had in her wallet

→ Assume that the amount she had in her wallet is $x

∴ 25% of x = 88

→ Change 25% to decimal by divide it by 100

∵ 25% = [tex]\frac{25}{100}[/tex] = 0.25

∴ 0.25 × x = 88

∴ 0.25x = 88

→ Divide both sides by 0.25 to find x

∴ [tex]\frac{0.25x}{0.25}=\frac{88}{0.25}[/tex]

∴ x = 352

∵ x represents the total amount she had in her wallet

∴ She had $352 in her wallet

Question 2:

∵ Kendrick caught 22 rainbow trout and 18 tiger trout while fishing

  last month

∴ The number of rainbow trout = 22

∴ The number of tiger trout = 18

→ To find the percent of tiger trout divide its number by the total number

   of trout, then multiply the result by 100%

∵ The total number of the trout = 22 + 18 = 40

∴ The percent of the tiger trout = [tex]\frac{18}{40}[/tex] × 100%

∴ The percent of the tiger trout = 45%

∴ The percent of the trout were the tiger trout is 45%

A) f'(x) = 0.3((x-1)²+1)

Step-by-step explanation:

Complete the square to rewrite the quadratic:

2 x² + 3 x + 5 = 2 (x² + 3/2 x) + 5

... = 2 (x² + 3/2 x + 9/16 - 9/16) + 5

... = 2 (x² + 3/2 x + (3/4)²) + 5 - 9/8

... = 2 (x + 3/4)² + 31/8

Any real number squared becomes non-negative, so the quadratic expression has a minimum value of 31/8, which is greater than 0, and so there are no (real) x for which y = 0.

Complete question :

A clinical psychologist has developed a new measure for assessing alcohol abuse. In a normal (non-clinical) sample, he found that his measure had a mean equal to 85 and a standard deviation equal to 15. Identify the score 25th, 75th, 95th

Answer:

1.) 25th percentile = 74.95

2.) 75th percentile = 95.05

3.) 95th percentile = 109.75

Step-by-step explanation:

Given that :

Mean (m) = 85

Standard deviation (s) = 15

The Zscore, corresponding to the percentiles given:

25th percentile score corresponds to a Zscore of - 0.67

Recall the relation:

Zscore = (x - m) / sd

x = score; m = mean = 85 ; sd = standard deviation = 15

-0.67 = (x - 85) / 15

15 * - 0.67 = x - 85

-10.05 = x - 85

x = 74.95

2.) 75th percentile ; Zscore = 0.67

0.67 = (x - 85) / 15

15 * 0.67 = x - 85

10.05 = x - 85

x = 10.05 + 85

x = 95.05

3.) 95th percentile ; Zscore = 1.65

1.65 = (x - 85) / 15

15 * 1.65 = x - 85

24.75 = x - 85

x = 24.75 + 85

x = 109.75

Answer:

The value is  [tex]\sigma _x = 1.1832[/tex]

    The population standard deviation is  [tex]\sigma = 7[/tex]

    The sample size is  n =  35

Generally the standard deviation of the sampling distribution is mathematically represented as

       [tex]\sigma _x = \frac{\sigma}{\sqrt{n} }[/tex]

=>    [tex]\sigma _x = \frac{7}{\sqrt{35} }[/tex]

Answer:

A) There is a rational relationship, B) Given ratio is not an integer.

Step-by-step explanation:

A) Is the relationship in Part A rational or irrational? Justifty your answer.

From Mathematics we remember that a rational number can formed by dividing a natural number by another natural number. Since Kara and Nathan had two natural numbers {32, 40} as their times of participation in the maze race, ratio between those times can be considered a rational number.

Hence, there is a rational relationship.

B) Can the times for each be written as integers?

The times represents the ratio of the upper number (40) to the lower number (32), the "times" can be written as integer if and only if denominator is equal to 1 after simplifying the ratio. That is:

[tex]x = \frac{40}{32}[/tex]

[tex]x = \frac{20}{16}[/tex]

[tex]x = \frac{10}{8}[/tex]

[tex]x = \frac{5}{4}[/tex]

In consequence, this ratio does not represent an integer. ([tex]1.25=\frac{5}{4}[/tex])
