Answer:

[tex]j^{13}[/tex]  is correct. This expression is showing j to the 13 power.

The equivalent expression is [tex]j^{13}[/tex]

Option C is the correct answer.

We have,

The expression:

j (j) (j) (j) (j) (j) (j) (j) (j) (j) (j) (j) (j)

There are 13 j's so,

This can be written as,

[tex]j^{13}[/tex]

Thus,

The equivalent expression is [tex]j^{13}[/tex]

Answer:

3

Step-by-step explanation:

Given

y = mx ( m is the constant of proportionality )

Given y = 12 when x = 4 , then

12 = 4m ( divide both sides by 4 )

3 = m ← constant of proportionality

Answer:

m = 3

Step-by-step explanation:

Find the constant of proportionality by plugging in x and y into the equation, and solving for m

y = mx

12 = m(4)

Divide each side by 4

3 = m

So, the constant of proportionality is 3

Answer:60 donut boxes and 160 cookies

Step-by-step explanation:

Multiply the boxes of donuts by $3, multiply the cookies by $1, add those two answers together to see if they equal at least 350

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The option that can not be a way to earn enough money is

Selling 60 boxes of donuts and 160 bags of cookies.

Option D is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount needed to earn = $350 or more

Profit from a box of donuts = $3

Profit from a box of cookies = $1

Now,

Selling 25 boxes of donuts and 290 bags of cookies.

= 25 x 3 + 290 = 75 + 290 = $365

Selling 30 boxes of donuts and 260 bags of cookies.

= 30 x 3 + 260 = $350

Selling 45 boxes of donuts and 220 bags of cookies.

= 45 x 3 + 220 = 135 + 220 = $355

Selling 60 boxes of donuts and 160 bags of cookies.

= 60 x 3 + 160 = 180 + 160 = $340

Thus,

The option that can not be a way to earn enough money is

Selling 60 boxes of donuts and 160 bags of cookies.

Option D is the correct answer.

Answer:

None of the colors

Step-by-step explanation:

The given parameters can be represented as:

[tex]Silver = 3[/tex]

[tex]Red = 3[/tex]

[tex]Green = 3[/tex]

[tex]Orange =1[/tex]

[tex]Total = 10[/tex]

Required

Which has a probability of 12%

To do this, we calculate the probability of each color.

This is calculated as:

[tex]P(Color) = \frac{Color}{Total}[/tex]

So, we have:

[tex]P(Silver) = \frac{Silver}{Total}[/tex]

[tex]P(Silver) = \frac{3}{10}[/tex]

Express as percentage

[tex]P(Silver) = 30\%[/tex]

[tex]P(Red) =\frac{Red}{Total}[/tex]

[tex]P(Red) =\frac{3}{10}[/tex]

Express as percentage

[tex]P(Red) =30\%[/tex]

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Express as percentage

[tex]P(Green) = 30\%[/tex]

[tex]P(Orange) = \frac{1}{10}[/tex]

[tex]P(Orange) = 0.1[/tex]

Express as percentage

[tex]P(Orange) = 10\%[/tex]

So, we have:

[tex]P(Silver) = 30\%[/tex]

[tex]P(Red) =30\%[/tex]

[tex]P(Green) = 30\%[/tex]

[tex]P(Orange) = 10\%[/tex]

From the above calculations, none of the colors have a probability of 12%.

Answer:

the number of cups of strawberries needed in the recipe is ⁵/₄

Step-by-step explanation:

Given;

cups of strawberries needed for the smoothies =  1 and 1/4 cups

To obtain the number of cups of strawberries needed in the recipe as a single fraction, the given mixed fractions will be converted into an improper fraction.

Note: Improper fractions are always greater than 1

Number of cups of strawberries [tex]=1 + \frac{1}{4} = \frac{4 + 1}{4} = \frac{5}{4}[/tex]

Therefore, the number of cups of strawberries needed in the recipe is ⁵/₄

Answer:

68%

Step-by-step explanation:

Empirical rule formula

= 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 16 years

Standard deviation = 1.7 years

Score = 14.3 years

We have to find the number of standard deviation to determine the percentage

Hence,

14.3 = 16 - 1.7x

Collect like terms

1.7x = 16 - 14.3

1.7x = 1.7

x = 1.7/1.7

x = 1

This means the data falls within 1 standard deviation from the mean hence, the probability of the gorilla living longer than 14.3 years is 68%
