Kimberly tracked the cartoons shown on the channel her kids watch for a week. The probability that the show had animals in it was 0.7 . The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?

Answer: [tex]y=5.666667[/tex]   or   [tex]y=5 \frac{6}{9}[/tex] in fraction

Step-by-step explanation:

1. Simplify  -9.8-y+2.8y  to  -9.8+1.8y

0.4=-9.8+1.8y0.4=−9.8+1.8y

2. Regroup terms

0.4=1.8y-9.8

3. Add 9.8 to both sides.

0.4+9.8=1.8y

4. Simplify  0.4+9.8  to  10.2

10.2=1.8y

5. Divide both sides by 1.8

[tex]\frac{10.2}{1.8} =y\\[/tex]

6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667

5.666667 = [tex]y[/tex]

7. Switch sides.

[tex]y=5.666667[/tex]

Answer:

See below.

Step-by-step explanation:

We have the expression:

[tex]\sqrt{8c+4}[/tex]

And we want to determine the domain restrictions of the expression.

Remember that the radicand (expression under the square root) must always be positive or 0. This is because we can't take the square root of a negative (and the square root of 0 is just 0). So, to find the domain restrictions, we can write and solve for the following inequality:

[tex]8c+4\geq0[/tex]

This is saying (8c+4) must be greater than or equal to 0. In other words, it's positive or 0.

So, solve for c. Subtract 4 from both sides:

[tex]8c\geq-4[/tex]

Now, divide both sides by 8. This yields:

[tex]c\geq4/8\\c\geq -1/2[/tex]

So, our c must be greater than or equal to -1/2. If it is less than -1/2, we won't have a solution.

Answer:

d-2x-3

Step-by-step explanation:

The factor of the trinomial will be (2x + 3) and (2x + 3). Then the correct option is D.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The trinomial is given below.

⇒ 4x² + 12x + 9

Then the factor of the trinomial will be

⇒ 4x² + 12x + 9

⇒ 4x² + 6x + 6x + 9

⇒ 2x(2x + 3) + 3(2x + 3)

⇒ (2x + 3)(2x + 3)

⇒ (2x + 3)²

Then the correct option is D.

Answer:

The correct option is;

Low

Step-by-step explanation:

Given that the P-value of the linear correlation = 0.001, we have that the P-value is a demonstration that a linear correlation that has a value in the range of the given correlation is ,most arguably very low

From the z-table, a P-value of 0.001 corresponds to a z-value of -3.09, we have that in a normal distribution since 95% of the scores have a z-score of between -2 and 2, the z-score of -3.09 is very distant from the mean and having a low value, whereby the P-value shows that the likelihood of finding another linear correlation that is as far from the mean as the given correlation  is very low.

Answer: Actual length of the bus = 171.67 feet

Width of the lake on the scale drawing = 12.5 inches

Step-by-step explanation:

Given : A scale drawing of a school bus has a scale of 12 inch to 5 feet.

i.e. 12 inch = 5 feet

[tex]\Rightarrow \text{ 1 inch}=\dfrac{5}{12}\text{ feet}[/tex]

If length of school bus on scale drawing = 412 inches

Then, Actual length of bus = [tex]\dfrac{5}{12}\times412=171.67\ \text{feet}[/tex]

A scale drawing of a lake has a scale of 1 cm to 80 m.

If the actual width of the lake is 1,000 m

then, the width of the lake on the scale drawing = [tex]\dfrac{1000}{80}=12.5\text{ inches}[/tex]

Answer:

A

Step-by-step explanation:

Given

x² - 5x - 14 = 0

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are - 7 and + 2, since

- 7 × 2 = - 14 and - 7 + 2 = - 5, thus

(x - 7)(x + 2) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 2 = 0 ⇒ x = - 2

Answer:

A. x=-7, x=2

Answer:

14 miles

Step-by-step explanation:

You divide. 132/13

Which gives you 14. Every 14 miles, the riders replaced a horse.

So, They rode 14 miles before replacing each horse.

Hope this helps:)

Answer:

14 miles

Step-by-step explanation:

182/13 = 14 miles

Assuming each horse was only ridden once

then a total of 16 horses were ridden for a total of 182 miles

182 miles /13  horses  = 14  miles  horse

Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.

Note that the fact that there were 3 riders is irrelevant.
