Answer:

[tex]\sqrt{2}[/tex] and 4[tex]\sqrt{11}[/tex]

Step-by-step explanation:

To simplify like surds, add/ subtract the coefficients.

(a)

[tex]\sqrt{2}[/tex] (6 - 5)

= [tex]\sqrt{2}[/tex] (1)

= [tex]\sqrt{2}[/tex]

(b)

[tex]\sqrt{11}[/tex] ( 1 + 3)

= [tex]\sqrt{11}[/tex] (4)

= 4[tex]\sqrt{11}[/tex]

Answer:

y = 7

Step-by-step explanation:

we can substitute y for 7 in the equation to confirm that y = 7

7 + 4 = 2(7) - 3

7 + 4 = 14 - 3

11 = 14 - 3

11 = 11

Answer:

[tex]4(46 + 3) + 2b = 3(6 - 11) \\ 184 + 12 + 2b = 18 - 33 \\ 196 + 2b = - 15 \\ 2b = - 15 - 196 \\ \frac{2b}{2} = \frac{ - 211}{2} \\ b = - 105.5[/tex]

Answer:

C

The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.4 eggs.

The correct interpretation of the standard deviation of the discrete distribution is:

In this problem, the distribution is:

[tex]P(X = 0) = 0.02[/tex]

[tex]P(X = 1) = 0.03[/tex]

[tex]P(X = 2) = 0.07[/tex]

[tex]P(X = 3) = 0.12[/tex]

[tex]P(X = 4) = 0.30[/tex]

[tex]P(X = 5) = 0.28[/tex]

[tex]P(X = 6) = 0.18[/tex]

Hence, the mean is:

[tex]E(X) = 0.02(0) + 0.03(1) + 0.07(2) + 0.12(3) + 0.3(4) + 0.28(5) + 0.18(6) = 4.21[/tex]

Then, the standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{0.02(0-4.21)^2 + 0.03(1-4.21)^2 + 0.07(2-4.21)^2 + 0.12(3-4.21)^2 + 0.3(4-4.21)^2 + 0.28(5-4.21)^2 + 0.18(6-4.21)^2} = 1.40[/tex]

Hence, the correct option is:

As the measure is the number of eggs, not the mean number of eggs.

Answer:

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

188 - 18 = 170 divided by 5 equals 34

Answer:

34 students per bus

Step-by-step explanation:

188 - 18 = 170, The number 170 is the total amount of students who were on buses

170 ÷ 5 = 34 This is the total number of students divide by the number of buses which gave the number of how many students were in each bus

Answer:

k = 1

Step-by-step explanation:

[tex]10=k+3+6k\\\\10=k+6k+3\\\\10=7k+3\\\\10-3=7k+3-3\\\\7=7k\\\\\frac{7=7k}{7}\\\\\boxed{1=k}[/tex]

Hope this helps.

Answer:

K=1

Step-by-step explanation:

So first you would add the K's together.(6k+k=7k)

10=7k+3

Then you would subtract 3 from 3 and 10

7=7k

Divide 7 on both sides

k=1

Answer:

12.90%

Step-by-step explanation:

Given ;

Original price = 171.50

Sale price = 149.37

To find the % markdown :

Markdown = Purchase price - sale price

171.50 - 149.37 = 22.13

(Markdown / purchase price) * 100%

(22.13 / 171.50) * 100%

0.1290379 * 100%

= 12.90%

Answer: Q1.=145, Q2.=20

Step-by-step explanation:

two supplementary angles equal 180

1. 180-35=145

2 . complementary angles , both add up to 90

90-70=20

Answer:

yes they are

Step-by-step explanation:

4:20 can be simplified till 1:5

Answer:

Yes

Step-by-step explanation:

If you simplify 4:20 by dividing both sides by 4, you'll end up with 1:5, meaning they are equivalent.

Answer:

187.96 cm

(answer d)

Answer:

Company A has a greater daily rate

Step-by-step explanation:

Given

Company A

[tex]Base\ Charges=\$50[/tex]

[tex]Daily\ Rate = \$150[/tex]

Company B

[tex]f(x) = 50(2x +1)[/tex]

Required

Determine the company with greater rate

Simplify the expression of company B

[tex]f(x) = 50(2x +1)[/tex]

[tex]f(x) = 50 * 2x + 50 * 1[/tex]

[tex]f(x) = 100x + 50[/tex]

In a linear function:

[tex]f(x) = mx + b[/tex]

m represents the rates.

This implies that the rate of company B is:

[tex]Rate =100[/tex]

and the rate of company A is

[tex]Daily\ Rate = \$150[/tex]

By comparison:

Company A has a greater daily rate

Answer:

Answer:

Step-by-step explanation:

Answer/Step-by-step explanation:

Opposite angles of a parallelogram are equal to each other.

Therefore, <S = <U, and <T = <V

Consecutive angles of a parallelogram are supplementary.

Therefore,

m<S + m<V = 180°

50° + m<V = 180°

m<V = 180° - 50° (subtraction property of equality)

m<V = 130°

Answer:

A. 432=18x

B. 22-see explanation

C. 24

D. See if your rounded answer and the actual answer are close.

Step-by-step explanation:

A. He buys a new phone for $432, and pays each month. We will use the variable x, and "x" will represent how many months he pays. It says that he pays $18 per month, so the equation would be 432=18x.

B. We need to isolate x, and to do this we have to divide 432 by 18. To approximate this answer, round 432 to 440 and 18 to 20. Now, divide 440 by 20. We get 22, so this will be the estimation.

C. Divide 432 by 18. We get 24.

E. You can see if it is reasonable if they are close in value.
