Answer:

50 penguins

Step-by-step explanation:

Let the total number of penguins = x

30% of x = 15

[tex]\frac{30}{100}*x=15\\\\\\x=15*\frac{100}{30}\\\\x=50[/tex]

Answer:

50

Step-by-step explanation:

15 x 100 equals 1500

1500 divided by 30 equal 50

Hopefully this helps you :)

pls mark brainlest ;)

no this is not enough chairs!

if you have 6 rows of 11 chairs it would look like this

xxxxxx

xxxxxx

xxxxxx

xxxxxx

xxxxxx

(each x is a chair)

this would mean to figure out the amount of chairs you set down you would do 6 x 11 which is 66. so you would need 4 more chairs to fit all 70 people.

Answer:

x=-6

Step-by-step explanation:

2x=-4-8

2x=-12

2x/2=-12/2

x=-6

Answer:

x = - 6

Step-by-step explanation:

2x+8 = 4

Subtract 8 from both sides:

2x+8-8 = - 4 - 8

Simplify :

2x = -12

Divide both sides by 2 :

2x/2 = -12/2

Simplify  :

-12/2 : -6

x = -6

=========================================================

Explanation:

n = numerator polynomial = unknown (what we want to solve for)

d = denominator polynomial = x-2

q = quotient = x-6

r = remainder = -6

Based on that, we can say,

n/d = q + r/d

n = q*d + r ... multiply every term by d

n = (x-6)(x-2) + (-6) .... substitution

n = x^2-8x+12-6

n = x^2-8x+6

Dividing (x^2-8x+6) over (x-2) leads to a quotient of (x-6) and a remainder of -6.

Answer:

[tex]5.4x+15[/tex] inches

Step-by-step explanation:

This is an equilateral triangle.

Therefore, all sides are equal to each other. This means that we don't need to go through the whole hassle of adding up all the sides together. We can just take the easiest side and multiply it by 3 (as the perimeter of an equilateral triangle is [tex]3s[/tex], s being the side length.)

In my opinion, the side [tex]1.8x+5[/tex] is the easiest to work with.

Let's multiply this by 3.

[tex]3(1.8x+5)[/tex]

We can apply the distributive property - multiply all terms inside the parentheses by 3.

[tex]1.8\cdot 3 = 5.4\\5\cdot3 = 15\\\\5.4x+15[/tex]

Hope this helped!

Answer: 503.8

Step-by-step explanation: 503.782 is the original fraction. To round up the number has to be 5, 6, 7, 8, or 9. The number in the hundredths place is 8. so that means the number in the tenths place can be moved up to 8 since 7+1=8.

Answer:

0.6125

Step-by-step explanation:

We have,

P(ripe avocados) = 0.45 , n = 5

by binomial distribution,

P(x=k) = [tex]${\overset{n}C}_k P^k(1-P)^{n-k}$[/tex]

P(2 ≤ x ≤ 3) = P(x=2) + P(x=3)

P(x=2) = [tex]${\overset{5}C}_2(0.45)^2(0.55)^3$[/tex]

           = 10 x (0.45)² x (0.55)³

           = 0.3369

P(x=3) = [tex]${\overset{5}C}_3(0.45)^3(0.55)^2$[/tex]

           = 10 x (0.45)³ x (0.55)²

           = 0.2756

So, P(2 ≤ x ≤ 3 ) = 0.3369 + 0.2756

                          = 0.6125

Answer:

Sqrt(7) is irrational because 7 is not a perfect square.

7.1234... is irrational because it is a nonterminating nonrepeating decimal.

Step-by-step explanation:

A rational number is a number that can be expressed in terms of fractions which result in terminating decimals, repeating decimals, or integer values.

An irrational number is a number that cannot be expressed in terms of fractions resulting in nonrepreating nonterminating decimals.

All options other than the two selected do not make sense.  Pi is irrational because it is a nonrepeating nonterminating decimal.

Answer: it will take 8 periods of 1/2 hour to make up 4 hours

Step-by-step explanation:

It will take 8 periods of 1/2 hour to make up 4 hours.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Half an hour is 30 minutes,

There are 60 minutes in an hour.

4 hours=240 minutes.

240/30 = 8

Hence, 8 periods of 1/2 hour to make up 4 hours.

Answer: in the domain of this situation, there is no asymptote.

Step-by-step explanation:

Asymptote would be on the left where x is negative but this function only shows all positive values of X

The value of k is -0.25. The graph shows that the actual number of consoles sold is slightly higher than the predicted number of consoles sold.

The graph shows that the number of consoles sold each day after the launch of the Brighton Company gaming console follows an exponential decay pattern. This means that the number of consoles sold each day is decreasing at a rate that is proportional to the number of consoles that have already been sold.

The equation that can be used to model this exponential decay pattern is:

N = A * [tex]e^{-kt[/tex]

where:

N is the number of consoles sold on day t

A is the initial number of consoles sold (200 consoles)

k is a constant that determines the rate of decay

e is the base of the natural logarithm

We can use the data from the graph to estimate the value of k. The first day after the launch, 180 consoles were sold. This means that on day 1, N = 180. The initial number of consoles sold, A, is known to be 200 consoles. Therefore, we can write the following equation:

180 = 200 * [tex]e^{-kt[/tex]

Solving for k, we get:

k = -ln(1.8) / 1

≈ -0.25

The value of k is approximately -0.25. This means that the number of consoles sold each day is decreasing at a rate of 25%.

We can use the equation to predict the number of consoles sold on future days. For example, on day 2, we would predict that 150 consoles would be sold. On day 3, we would predict that 120 consoles would be sold.

The graph shows that the actual number of consoles sold is slightly higher than the predicted number of consoles sold. This is because the exponential decay pattern is not perfect. There are other factors that can affect the number of consoles sold, such as the availability of the console and the price of the console.

Answer:

b) 1.34

Step-by-step explanation:

The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

For the largest 9%, the score is 100% - 9% = 91% = 0.91

From the normal distribution table, the z score that corresponds to 0.91 is 1.34
