Answer:

The percentage of people that scored less than Calvin is 38.21 %

Step-by-step explanation:

In this question, we are concerned with calculating the percentage of exam scores lesser than what Calvin scores.

To calculate this, we first need to calculate the standard score or the z-score of Calvin result.

Mathematically;

z = (x - mean)/SD

from the question, x = 78, mean = 81 and SD = 10

Substituting this, we have

z = (78 -81)/10 = -3/10 = -0.3

So we proceed to calculate the probability.

P(x < 78) or P(z < -0.3)

We make use of the standard table to get this probability

P(z< - 0.3) = 0.38209

In percentage, this is same as 38.209% or more simply 38.21%

Answer:

48 months

Step-by-step explanation:

Brandon estimates that he will need $18,000 each year to attend a 4-year college.

His family can pay $5,000 a year and he can get a student loan for $10,000 each year.

This means that, each year, $15000 out of the $18000 has been covered. That is the sum of the money from his parents and the loan:

$5000 + $1000 = $15000

That means the amount he still needs to cover per year is:

$18000 - $15000 = $3000

In 4 years, he will need to cover:

4 * $3000 = $12000

He saves $250 a month. Therefore, the number of months he will need to save $12000 is:

[tex]\frac{12000}{250} = 48 months[/tex]

He will need to save for 48 months to save the rest of the money he will need for College.

Answer: It will take him 48 months.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

the amount his family can pay per year (5000) multiplied by 4 (since is a 4 year college) ; plus the amount of the loan he gets per year (1000) also multiplied by 4 ; plus the amount he saves per month (250) multiplied by the number of months (m) must be equal to the amount he will need per year for college (18000) multiplied by 4.

Mathematically speaking

18000 x 4 = (5000 x 4) + (10000x 4) + 250 m

Solving for m

72000= 20,000+ 40,000+ 250m

72,000-20,000-40,000 = 250m

12,000= 250m

12,000/250 = m

48 =m

Kevin can cut approximately 2 pieces of 14-inch-long trim from his 3-foot-long trim, with about 0.66667 feet left over.

To find out how many 14-inch-long pieces Kevin can cut from a 3-foot-long trim, we need to convert everything to the same unit. Since Kevin's trim is given in feet, we need to convert inches to feet to make the comparison easier.

[tex]1 foot = 12 inches[/tex]

So, 14 inches is equal to:

[tex]\[14 \text{ inches} \times \frac{1 \text{ foot}}{12 \text{ inches}} = \frac{14}{12} \text{ feet}\][/tex]

[tex]\[= 1.16667 \text{ feet}\][/tex]

Now, we can find out how many 14-inch-long pieces Kevin can cut from the 3-foot-long trim:

[tex]\[ \text{Number of pieces} = \frac{\text{Length of trim}}{\text{Length of each piece}} \][/tex]

[tex]\[ \text{Number of pieces} = \frac{3 \text{ feet}}{1.16667 \text{ feet}} \][/tex]

[tex]\[ \text{Number of pieces} \approx 2.571 \][/tex]

Now, let's find out how much of a foot will be left over:

[tex]\[ \text{Leftover} = \text{Length of trim} - (\text{Number of pieces} \times \text{Length of each piece}) \][/tex]

[tex]\[ \text{Leftover} = 3 \text{ feet} - (2 \times 1.16667 \text{ feet}) \][/tex]

[tex]\[ \text{Leftover} = 3 \text{ feet} - 2.33333 \text{ feet} \][/tex]

[tex]\[ \text{Leftover} \approx 0.66667 \text{ feet} \][/tex]

Complete correct question:

Kevin is making a picture frame. He has a piece of trim that is 3 feet long.

How many 14-inch-long pieces can Kevin cut from the trim?

How much of a foot will he have left over?

Kevin can cut ______ 14-inch-long pieces with ______ of a foot left over.

Answer: D. Dividing

Step-by-step explanation:

When we divide a number ( whether fraction or not ) by a fraction, then we first change the operator to multiplication and  reciprocate the second fraction.

Let's take an example:

Suppose we have h division problem in fraction as [tex]\dfrac{2}{3}\div\dfrac{4}{9}[/tex]

Then, our first step would be to change division operator (÷) by multiplication operator (×) and then ×reciprocate the second fraction , so the next step will become [tex]\dfrac{2}{3}\times\dfrac{9}{4}[/tex] , Now cancel out 3 and 2 from both numerator and denominator , we get

[tex]\dfrac{1}{1}\times\dfrac{3}{2}=\dfrac{3}{2}[/tex]

i.e. [tex]\dfrac{2}{3}\div\dfrac{4}{9}=\dfrac{3}{2}[/tex]

Hence, the correct option is "D. Dividing".

The first step which involves changing the operator to multiplication of the reciprocal of the second fraction is when dividing.

If given

5/2 ÷ 1/2

The first step is to multiply with the reciprocal of the second fraction

= 5/2 × 2/1

= (5 × 2) / (2 × 1)

= 10/2

= 5

Therefore, when dividing fraction, we multiply with the reciprocal of the second fraction.

Answer:

B

Step-by-step explanation:

Our system of equations is:

3x + y = 23

8x + 2y = 23

If we want to use substitution, that means that we essentially want to manipulate one of the two equations so that one variable (like y) is written in terms of the other (like x), and then substitute that expression into the second equation so that we have one variable and one equation and we can easily solve from there.

So the first thing to be done is to write one of the variables in terms of the other. It would be easiest to do it with the first equation and write y in terms of x - in other words, "solve the first equation for y".

The answer is B.

9,900 millimeters squared

Step-by-step explanation:

The area of the composite figure having bases 210mm, 150mm and height 55mm is ; 19800 millimeters squared.

A trapezoid is a quadrilateral with one pair of parallel sides.

Analysis:

Area of a trapezoid = 1/2(a + b )h

where a = small base, b = big base and h = height

From given data: a = 150mm, b = 210mm, h = 55mm

Area of trapezoid = 1/2(150+210) x 55 = 9900[tex]mm^{2}[/tex]

Answer:

Cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Step-by-step explanation:

Let the cost of water bottle = $a

Cost of 1 gallon milk = $b

and cost of 1 bag of chips = $c

So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)

4b + 6a + 5c = 27.2 -----(1)

Cost of one water bottle = 2 × cost of one bag of chips

a = 2c -----(2)

A gallon of milk = cost of water bottle + $1.80

b = a + 1.8

From equation (2)

b = 2c + 1.8 -----(3)

Now we substitute these values from equations (2) and (3) in equation (1)

4(2c + 1.8) + 6(2c) + 5c = 27.2

8c + 7.2 + 12c + 5c = 27.2

25c = 27.2 - 7.2

c = [tex]\frac{20}{25}[/tex]

c = $0.8

From equation (2)

a = 2×0.8

a = $1.6

From equation (3)

b = 2(0.8) + 1.8

b = 1.6 + 1.8

b = $3.4

Therefore, cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Final answer:

A snack size bag of chips costs $0.80, a bottle of water costs $1.60, and a gallon of milk costs $3.40. This was determined by creating an equation with the given cost relationships and solving for the cost of each item.

Explanation:

The question presents a scenario where a trip to the convenience store involves purchasing 4 gallons of milk, 6 bottles of water, and 5 snack size bags of chips with a total bill of $27.20 before tax. The cost relationships given are: a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water.

Let's denote the cost of a snack size bag of chips as c. Thus, the cost of a bottle of water would be 2c. A gallon of milk would then cost 2c + $1.80.

To find the cost of each item, we can set up an equation based on the total cost:

5c + 6(2c) + 4(2c + $1.80) = $27.20

Solving this equation:

5c + 12c + 8c + $7.20 = $27.20

25c + $7.20 = $27.20

25c = $20

c = $0.80

Therefore, a snack size bag of chips costs $0.80, a bottle of water costs $1.60, and a gallon of milk costs $3.40.

Answer:

Consecutive whole numbers (or integers) are numbers that directly follow one another.

Eg: 1, 2, 3, 4, 5 are consecutive whole numbers.

Step-by-step explanation:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

or

let the three consecutive whole numbers is x, x+1,and x+2

x + x+1 + x+2 = 4+2(x+1)

3x+3=4+2x+2

3x-2x=6-3

x=3

the other two numbers are 3+1=4,and 3+2=5

so the three numbers are 3,4 and 5

The probability that the sum of two dice is 7 given that the purple die landed on 6 is 1/6, as only one outcome from the green die (rolling a 1) will achieve this sum.

The question is about calculating the conditional probability of rolling a sum of 7 on two dice, given that the purple die has already landed on 6. Since we know the outcome of the purple die, we only need to determine the probability that the green die will land on a 1 to make the sum 7 (6 from the purple die and 1 from the green die).

There are 6 possible outcomes when rolling a six-sided die. Since only one of these outcomes (rolling a 1) will result in the sum of 7 when the purple die is a 6, the conditional probability is 1/6.
