Answer:

Katrina would need to buy 20 sweatshirts.

Step-by-step explanation:

The number of sweatshirts Katrina would need to order from  each company can be determined by forming the linear equation in two variables.

Given :

Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.

So, the cost for ordering the sweatshirt from the company MH Design is:

[tex]21.50x = c[/tex]

Now, the cost for ordering the sweatshirt from the company Print Rich is:

18y + 70 = c'

Given that the number of sweatshirts Katrina would need to order from  each company for the costs to be the same. So :

21.5x = 18y + 70

Now, put the value of x and y so, that in the above equation, both sides become equal.

Answer:

75 Degrees

Step-by-step explanation:

We know that all the angles of a triangle add up to 180.

We also know the each angle of triangle DEF in terms of variables

All we have to do is add the 3 angles which equal a total of 180 Degrees.

Angle D+E+F = 180 Degrees

(5+x) + (6+4x) + (4x) = 180

9x + 11 = 180

9x = 169

x = 18.8 Degrees

Angle F is 4x so it is 4(18.8) = 75 Degrees

This is what i got, I"m not sure what else im supposed to solve for. The multiple choice doesnt make sense.

Answer:

$1.5 per container

Step-by-step explanation:

First, subtract the cost of the chips from the total purchase cost. This equals 4.5. Then, divide 4.5 by 3 to find the cost of each individual container of milk. You get 1.5. This means that each container was $1.50. Hope this helps :)

Answer: 220%

Step-by-step explanation:

165 of 75 can be written as:

165 /75

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

165 /75  ×  100 /100  = ( 165 × 100 /75 ) ×  1 /100  =  220 /100

Therefore, the answer is 220%

Answer:

[tex]\dfrac{1}{8}\ \text{gallons}[/tex]

Step-by-step explanation:

Amount of milk remaining is [tex]\dfrac{3}{4}\ \text{gallons}[/tex]

Number of bowls is [tex]6[/tex].

So, each bowl will contain

[tex]\dfrac{\dfrac{3}{4}}{6}[/tex]

[tex]=\dfrac{3}{4}\times \dfrac{1}{6}[/tex]

[tex]=\dfrac{3}{24}[/tex]

[tex]=\dfrac{1}{8}\ \text{gallons}[/tex]

Hence, each bowl will have [tex]\dfrac{1}{8}\ \text{gallons}[/tex] of milk.

Answer:

mean = 2

standard deviation = 1.3

Step-by-step explanation:

For a binomial random variable X, we can use this formula for mean:

meanX = np

We use this formula for the standard deviation:

sdX = sqrt(np(1 - p))

--------------------------------------------------------------------------------------------------

Since a turn consists of rolling 12 dice, we have n = 12.

The dice are fair and 6-sided, so the probability that each die lands showing "1" is p = 1/6.

meanX = np

= (12)(1/6)

= 2 dice

sdX = sqrt(np(1 - p))

= sqrt((12)(1/6)(5/6))

≈ sqrt(1.667)

≈ 1.291 dice

The mean and standard deviation of the game of luck are;

Mean = 2

Standard deviation = 1.29

We are told that a turn consists of rolling 12 fair six sided dice.

Thus;

n = 12

Probability of each one six sided die showing 1 is;

p = 1/6

Now,the formula for the mean is;

E(X) = np

Plugging in the relevant values gives;

E(X) = 12 × 1/6

E(X) = 2

Now, for the standard deviation, we will use the formula;

Standard deviation = √(np(1 - p))

Plugging in the relevant values;

Standard deviation = √((12 × 1/6)(1 - 1/6))

Standard deviation = 1.29
