Answer:

21

Step-by-step explanation

If 7 apples are 2.10 then for 4.20 its 14 apples.   And 3 apples is 90 cents.  1 apple is 0.30.  So the amount you can buy is 21 because 6.30/0.3 is 21

Answer:

21

Explanation:

If 7 apples cost y cents, how many can you buy for x dollars?

As y cents buy 7 apples, y dollars will buy 7×100 apples.

Hence one dollar will buy 7×100y=700y apples and,

x dollars will buy 700y × x apples or 700x y apples.

Hence 7 apples multiplied by $6.30 divided by $2.10 will get you 21 apples.

Answer:

Step-by-step explanation:

From the given information:

The number of different license plate the country  can produce is in the form:

=L₁L₂L₃L₄   or  L₁L₂L₃L₄L₅  or  D₁L₁L₂L₃L₄   or    D₁L₁L₂L₃L₄L₅

∴

The Total number of the license plate that can be produced is;

= 26⁴ + 26⁵ + (10 × 26⁴) + (10 × 26⁵)

= 456976 + 11881376 + 4569760 + 118813760

= 135721872

Number of license plate with no repeated letter = P(26,4) + P(26,5) + 10 P(26,4) + 10 P(26,5)

= 11 P(26,4P + 11 P(26,5)

[tex]=11 \times \dfrac{26!}{(26-4)!} + 11 \times \dfrac{26!}{(26-5)!}[/tex]

= 90776400

c) The number of the licensed plate with 1 repeated letter = Total number of the licensed plate - number of the licensed plate with no repeated letter.

= 135721872 - 90776400

= 44945472

d) The probability that a licensed plate has repeated letter is:

[tex]= \dfrac{no(rep \ letter) }{n (total)} \times 100\%[/tex]

[tex]= \dfrac{44945472}{135721872}\times 100\%[/tex]

= 33.12%

A) The country can produce 118,813,760 different licence plates.

B) 78,936,000 license plates have no repeated letter.

C) 39,877,760 license plates have at least one repeated letter.

D) The probability that a license plate has a repeated letter is 33.56%.

Given that in a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the Roman alphabet, to determine (A) how many different license plates can the country produce; (B) how many license plates have no repeated letter; (C) how many license plates have at least one repeated letter; and (D) what is the probability that a license plate has a repeated letter, the following calculations must be performed:

Answer:

Step-by-step explanation:

Answer:

Our y-intercept is (0, -36).

Our real zeros are: (-2√3, 0) and (2√3, 0)

And our imaginary zeros are: (i√3, 0) and (-i√3, 0)

Step-by-step explanation:

We have the function:

[tex]y=x^4-9x^2-36[/tex]

Let's identify the y- and x-intercepts.

Y-Intercept:

To determine the y-intercept, we will substitute 0 for x and solve for y. So:

[tex]y=(0)^4-9(0)^2-36[/tex]

Evaluate:

[tex]y=-36[/tex]

Therefore, our y-intercept is at (0, -36).

X-Intercepts:

To determine our x-intercepts, we need to substitute 0 for y and solve for x. So:

[tex]0=x^4-9x^2-36[/tex]

Now, we can factor. Before doing so, we can make the factored easier to see by converting this into quadratic form. Let's let u=x². Then:

[tex]0=(u^2)^2-9(x^2)-36[/tex]

Substitute:

[tex]0=u^2-9u-36[/tex]

Now, let's factor. We can use -12 and 3. So:

[tex]0=u^2+3u-12u-36 \\ 0=(u(u+3)-12(u+3)) \\ 0=(u-12)(u+3)[/tex]

Now, we can substitute back u:

[tex]0=(x^2-12)(x^2+3)[/tex]

Zero Product Property:

[tex]x^2-12=0\text{ or } x^2+3=0[/tex]

Solve for x in each case:

[tex]x^2=12 \text{ or } x^2=-3[/tex]

Take the square root of both sides. Since we're taking an even root, we will need plus/minus. Therefore:

[tex]x=\pm\sqrt{12}=\pm2\sqrt{3}\text{ or } x=\pm\sqrt{-3}=\pm i\sqrt{3}[/tex]

Therefore, our zeros (both real and imaginary) are: (2√3, 0), (-2√3, 0), (i√3, 0), and (-i√3, 0)

Step-by-step explanation:

The null hypothesis refers to a hypotheses that simply states that no relationship exists between two phenomenons that are being tested.

In testing the validity of a multiple regression model in which there are four independent variables, the null hypothesis is H0 : β1 = β2 = β3 = β4 = 0.

Sorry to break it to ya but the other answer is wrong and the correct answer is A. 36 cm^2

Step-by-step explanation:

1. Divide the figure into 2 figures.

2. Calculate the first figure by multiplying the length (7 cm) and width (4 cm).

3. After that, we get 28. Do the same to the other figure. (4 cm x 2 cm = 8 cm).

4. Combine the 2 areas to get your total area. (28 + 8 = 36 cm^2).

5. NEVER forget the "^2" meaning squared when calculating the area.

Hope this helps, have a good day/night. :)

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

The area of the figure is 36 cm².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

Example:

The area of the rectangle with a length of 3 cm and wide 5cm is 15 cm².

We have,

A figure.

The figure has two rectangles.

One rectangle:

Length = 4 cm

Wide = 7 cm

Area of the rectangle = 4 x 7 = 28 cm²

Another rectangle:

Length = 2 cm

Wide = 4cm

Area of the rectangle = 2 x 4 = 8 cm²

The area of the figure.

= 28 + 8

= 36 cm²

Thus,

The area of the figure is 36 cm².
