Answer: 130, sorry if its wrong

Step-by-step explanation:

8 x 5 = 40 --> 40 x 3 1/4 = 130

Answer:

80

Step-by-step explanation:

48 ÷ 6 = 8 per hour

8 x 10 hours = 80 dogs

Answer: Steve can train 80 dogs.

Step-by-step explanation:

How many dogs he can train divided by how many hours is: 48/6 = 8.
He is able to train 8 dogs per hour. So: 8 x 10 = 80.

Answer:

2/4, 4/8, 8/16, 16/32

Step-by-step explanation:

2/4
2x2/4x2 = 4/8
4x2/8x2 = 8/16
8x2/16x2 = 16/32

[tex] {x}^{2} - 8 = 8 \\ [/tex]

x^2 - 8 + 8 = 8 + 8

x^2 = 16

x = √16

x = 4

[tex]{\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}[/tex]

[tex] \blue{ {x}^{2} - 8 = 8}[/tex]

[tex] \purple{ {x}^{2} - 8 + 8 = 8 + 8}[/tex]

[tex] \red{ {x}^{2} = 16}[/tex]

[tex] \green{ \sqrt{ {x}^{2} } = \sqrt{16} }[/tex]

[tex] \pink{x = 4}[/tex]

For a graph to move up, we must add the value of how much we want to move up outside the function.

So if the original graph [tex]f(x) = x^2[/tex], thus [tex]g(x) = x^2 + 2[/tex]

Hope that helps!

Answer:

You can know if the shapes are similar if the are the same type of shape, have proportional side lengths, congruent corresponding angles (the angles are in the same place proportional to the shape and have the same amount of degrees), and equal scale factors.

In number 19, the polygons are similar because they have proportional side lengths and congruent corresponding angles.

Number 20's trapezoid A and B are not similar because the side lengths are not proportional to each other ( 2 is half of 4, 4 is not half of 6)

Answer:

86.5 square inches

Step-by-step explanation:

Area of circle: pi*r^2

10.5in /2= 5.25in

5.25^2=27.5625

27.5625*3.14=86.54625

rounded 86.5 in

Answer:

D.  18,000(0.97)^x

First, let's look at everything we know from reading the question.

We know that y = the population

We know that x = the number of years

We know the population starts at 18,000

We know the population is decreasing at a rate of 3% each year

Since the population is decreasing by 3%, the population will be 0.97 times the previous population each year.

This is because 100 - 3 = 97

That means we can make part of the equation.

y = 18,000(0.97)

Now, do we do 0.97^x or 0.97x?

Well, if we did 0.97x, it would look something like this

If x = 2

0.97(2) = 1.94

That means that, by 2 years, the population would be increasing when it should be decreasing

Now let's try 0.97^x

if x = 2

0.97^2 = 0.9409

That makes sense because the population would be decreasing by a slightly larger amount each time.

So, our final equation is

D.  18,000(0.97)^x

Lets check

[tex]\\ \rm\longmapsto P(1-r)^t[/tex]

[tex]\\ \rm\longmapsto P(1-0.03)^t[/tex]

[tex]\\ \rm\longmapsto 18000(0.97)^t[/tex]

The probability that Peter will pass the quiz is given by the option 3: 0.0035

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

For the considered case, the problem's statement is missing some facts.

They are:

Number of multiple choice questions in test = 10

Peter uses guessing for answering the questions.

To pass the test, Peter needs to get at least 7 correct answers.

Some probabilities on left are:

Let X be the number of questions peter gets correct in his test.

Then, the probability that he will pass the test is denoted as:

[tex]P(X \geq 7)[/tex]

This can be rewritten as:

[tex]P(X \geq 7) = P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)\\P(X \geq 7) =0.0031 + 0.000386 + 0.0000286 + 0.000000954 = 0.003515554[/tex]

This is approximately 0.0035

Thus, the probability that Peter will pass the quiz is given by the option 3: 0.0035

Answer:

  11.3

Step-by-step explanation:

The side opposite the given angle is unknown. The hypotenuse is also given. The trig function that relates the angle, opposite side, and hypotenuse is the sine function:

  Sin = Opposite/Hypotenuse

  sin(39°) = x/18

  x = 18·sin(39°) ≈ 11.3

Answer:

Step-by-step explanation:

Moving all terms of the quadratic to one side, we have

[tex]x^2-2x-(c+4)=0[/tex].

A quadratic has one real solution when the discriminant is equal to 0. In a quadratic [tex]ax^2+bx+d[/tex], the discriminant is [tex]\sqrt{b^2-4ad}[/tex].

(The discriminant is more commonly known as [tex]\sqrt{b^2-4ac}[/tex], but I changed the variable since we already have a [tex]c[/tex] in the quadratic given.)

In the quadratic above, we have [tex]a=1[/tex], [tex]b=-2[/tex], and [tex]d=-(c+4)[/tex]. Plugging this into the formula for the discriminant, we have

[tex]\sqrt{(-2)^2-4(1)(-(c+4))[/tex].

Using the distributive property to expand and simplifying, the expression becomes

[tex]\sqrt{4-4(-c-4)}=\sqrt{4+4c+16}\\~~~~~~~~~~~~~~~~~~~~~~=\sqrt{20+4c}\\~~~~~~~~~~~~~~~~~~~~~~=\sqrt{4}\cdot\sqrt{5+c}\\~~~~~~~~~~~~~~~~~~~~~~=2\sqrt{c+5}.[/tex]

Setting the discriminant equal to 0 gives

[tex]2\sqrt{c+5}=0[/tex].

We can then solve the equation as usual: first, divide by 2 on both sides:

[tex]\sqrt{c+5}=0[/tex].

Squaring both sides gives

[tex]c+5=0[/tex],

and subtracting 5 from both sides, we have

[tex]\boxed{c=-5}.[/tex]

Answer:

f=4

Step-by-step explanation:

so, when we do this problem notice that there is a variable this can mean a lot of things but in this case, it just means were solving for f so we first move the constant (5) to the right-hand side and change its sign then we subtract 33 from 5 to get 28 so the equation would look like 7f = 33-5

to get 7f = 28 and now for the last step you divide both sides of the equation to get f = 4

Answer:

i) 4 females

ii) 8 females

Step-by-step explanation:

1. Ratio of males= 3x

3x = 3

Thus, x = 1

If there are 3 males, there will be 4 females

2.Rato of males= 3x

3x = 6

Thus x = 2 [6 divided by 3]

4x = 4 x 2 = 8

If there are 6 males, there would be 8 females.
