Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer: 8,700

Step-by-step explanation:

lets say you have 500 animals, and you decide to get another 500, but you decide that you want an extra 500, and then your kid says that they want another 500 animals. You now have 2000 animals, but you also need 4000 chickens so you now have 6000 animals. Then you need 900 pounds of animal food, but 900 pounds is weird so you get an extra 100 to make your total 1000. But now you need 800 dogs so you now have 2800 animals.

4000 + (500 x 4) + 900 + 100 + 800 = 8,700

Answer:

The answer would be 8700

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Answer:

Step-by-step explanation:

You are finding out each time how much is the items Zachary bought.

Then inputting a equation

$1,600 - ??? = $1,370

To find the unknown number, you must subtract the 2 original numbers.

$1,600 - $1,370 = $230

Computer costs: $230 leaving Zachary with $1,370 left.

Next, it says he purchased another computer...

$1,370 - ??? = $1,140

Again, we subtract the 2 original numbers to find the unknown.

$1,370 - $1,140 = $230 leaving Zachary with  $1,140 left.

Now we input this data into an equation...

y = -230x + 1600.

Answer:

65 years old.

Step-by-step explanation:

Define the variables:

Given:

Create two equations with the given information and defined variables:

\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)

Substitute the first equation into the second equation and solve for x:

\(\implies 13x+1=11(x+1)\)

\(\implies 13x+1=11x+11\)

\(\implies 2x=10\)

\(\implies x=5\)

Substitute the found value of x into the first equation and solve for y:

\(\implies y=13(5)\)

\(\implies y=65\)

Therefore, the age of the grandparent now is 65 years.

Given statements:

Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.

    \(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)

Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.

To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.

Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.

Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.

To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:

But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.

Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.

Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.

Therefore, the age of the grandparent is 65 years.

Answer:

84 ounces

Step-by-step explanation:

Total pounds of popcorn bought = 64 pounds

1/4th kept for family ==> 1/4 * 64 = 16 lbs

Remainder = 64-16 = 48 lbs

1/8th of remainder to club ==> 1/8 * 48 = 6 lbs to club

Remainder left over = 48-6 = 42 lbs

Distributed 42 lbs between each of 8 friends equally
Each friend gets 42/8 lbs = (42/8) * 16 = 84 ounces

Since there are 16 ounces in a pound

From the given information each friend receives 84 ounces of popcorn.

Let's solve the problem using thee concept of Fractions

1. Miriam bought 64 pounds of popcorn.

2. She kept 1/4 of the popcorn for her family. So, the amount of popcorn left after this step is \(\(64 \times \frac{3}{4}\)\).

Now, let's calculate the popcorn remaining after Miriam keeps some for her family:

\(\(64 \times \frac{3}{4} = 48\)\) pounds.

Next, Miriam gave 1/8 of the remaining popcorn to her club, leaving her with \(\(48 \times \frac{7}{8}\)\) pounds.

Now, let's calculate the popcorn remaining after Miriam gives some to her club:

\(\(48 \times \frac{7}{8} = 42\)\) pounds.

Finally, she distributed the rest equally among 8 friends. To find out how much each friend gets, we'll divide the total popcorn left by the number of friends:

Amount each friend gets =\(\(\frac{42}{8}\)\) pounds.

The problem asks for the answer in ounces, not pounds.

To convert pounds to ounces, we know that 1 pound is equal to 16 ounces. So, to get the amount of popcorn each friend gets in ounces, we'll multiply the previous answer by 16:

Amount each friend gets = \(\(\frac{42}{8} \times 16\)\) ounces.

Amount each friend gets = \(\(84\)\) ounces.

So, each friend will get 84 ounces of popcorn.

In summary, Miriam's 64 pounds of popcorn were reduced to 42 pounds after sharing with her family and club. Finally, the remaining popcorn was divided equally among her 8 friends, with each friend receiving 84 ounces.

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.

To solve this problem, we can use the following equation:

total weight / number of bags = weight of each bag

In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:

1.5 pounds / 6 bags = 0.25 pounds per bag

Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.
