2/21 is the answer to the question

The probability of picking a chocolate chip cookie is 1/3.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A box contains 5 chocolate chip cookies, 4 sugar, and 6 oatmeal raisin.

N represents no. of.

So, N(S) = 5 + 4 + 6 = 15.

N(CC) = 5, N(SR) = 4 and N(OR) = 6.

∴  The probability of picking a chocolate chip cookie is = N(CC)/N(S).

= 5/15.

= 1/3.

what is the y intercept of x+ 7y = 35

Answers

Answer:

5

Step-by-step explanation:

get the equation into slope intercept form, y = mx +b

where b is the y-intercept

subtract x from both sides

7y = -x + 35

divide 7 from both sides

y = -1/7 x + 5

thus b = 5

Answer:
5

Explanation:
A linear equation is typically organized in the form y=mx+b. In this equation, b represents the y-intercept. Our goal is to rearrange the given equation into this form to identify b.

x+7y=35
Subtract both sides by x
x+7y-x=-x+35
7y=-x+35
Divide both sides by 7
7y/7=-1/7x+35/7
y=-1/7x+5

Now, we can tell clearly that the y-intercept of the equation is 5.

A rectangular magazine cover is photocopied by using a scale factor of One-third. The length of the photocopy of the magazine cover is enlarged by a factor of 3. enlarged by a factor of One-third. reduced by a factor of 3. reduced by a factor of One-third.

Answers

Answer: "reduced by a factor of One-third."

Step-by-step explanation:

Suppose that the original magazine has a length L and a width W.

If it is photocopied using a scale factor of K, then the measures of the photocopy will be:

length = K*L

Width = K*W

In this case, the scale factor is K = 1/3, then the measures of the photocopy will be:

length = (1/3)*L = L/3

Width = (1/3)*W = W/3

For usual notation:

When k > 1, we have an enlargement by a factor k

when 0 < k < 1, we have a reduction by a factor k

in this case, k = 1/3, then:

We have a reduction by a factor of 1/3

The correct option is:

"reduced by a factor of One-third."

Answer: D-reduced by a factor 1/3

The number of leaves more leaves does Sheila collect then Rodney is 6.

What is subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Given that, Rodney collects 17 leaves and Sheila collects 23 leaves.

Now, 23-17

= 6

Therefore, the number of leaves more leaves does Sheila collect then Rodney is 6.

Victoria is remodeling her house and she decides to paint a wall. She was able to cover 478.3 inches with the paint that she had. She figures out that this is only 92% of the total wall. How much space, in inches, does she have to paint total, including what she has already painted?

Answers

92% of the total space = 478.3 inches, let S represent the total space...
S x .92 = 478.3
divide both sides of the equation by .92 to solve for S...
S = 519.89

Frank and his family went on vacation one summer, and drove 3,000 miles in 10 days. If they drove an equal distance every day, how many miles a day did frank and his family drive.

Answers

Answer:

Distance cover by Frank and family each day = 300 miles per day

Step-by-step explanation:

Given:

Total distance cover by Frank and family = 3,000 miles

Number of days = 10

Find:

Distance cover by Frank and family each day

Computation:

Distance cover by Frank and family each day = Total distance cover by Frank and family / Number of days

Distance cover by Frank and family each day = 3,000 / 10

Distance cover by Frank and family each day = 300 miles per day

Answer:

C. 300

Step-by-step explanation:

Divide the distance by the time it took to travel that distance: 3,000 miles ÷ 10 days = 300 miles per day.

Find the sum of the first 8 terms of the series 3 + 6 + 9 + …, given that a8 = 24.

Answers

Step-by-step explanation:

You want to use the sum of an arithmetic sequence formula.

(a1 + an) × n/2

a1 is the first term and an is the last term. n is the number of terms.

In this case: (3+24) × 8/2 = 27×8/2 = 27×4 = 108

The sum of the first 8 terms of the series 3 + 6 + 9 + ... is 108.

To find the sum of the first 8 terms of the series, we need to find the common difference (d) and then use the formula for the sum of an arithmetic series.

Given that [tex]\(a_8 = 24\)[/tex], we can see that the 8th term is 24.

The formula for the nth term of an arithmetic series is [tex]\(a_n = a_1 + (n-1) \cdot d\)[/tex], where [tex]\(a_n\)[/tex] is the nth term, [tex]\(a_1\)[/tex] is the first term, and d is the common difference.

Substitute n=8 and [tex]\(a_n=24\)[/tex] into the formula:

[tex]\(24 = 3 + (8-1) \cdot d\)[/tex]

Simplify the equation:

[tex]\(24 = 3 + 7 \cdot d\)[/tex]

Now, solve for d:

[tex]\(7d = 24 - 3\)\\\\\(7d = 21\)\\\\\(d = \frac{21}{7} = 3\)[/tex]

Now that we have the common difference d = 3, we can use the formula for the sum of an arithmetic series:

[tex]\(S_n = \frac{n}{2} \cdot (a_1 + a_n)\)[/tex]

Substitute [tex]\(n=8\)[/tex], [tex]\(a_1=3\)[/tex], and [tex]\(a_n=24\)[/tex] into the formula:

[tex]\(S_8 = \frac{8}{2} \cdot (3 + 24)\)\\\\\(S_8 = 4 \cdot 27\)\\\\\(S_8 = 108\)[/tex]

So, the sum of the first 8 terms of the series is 108.

what is the prime factorization of 100

Answers

Answer:22 × 52

Step-by-step explanation:

Answer:

2 x 2 x 5 x 5

Step-by-step explanation:

since 2, 3, and 5 are prime numbers I always begin by seeing if the number to be factored has those as factors

100 is divisible by 2 so you can start there:

2 x 50

50 is divisible by 2 so you now have:

2 x 2 x 25

25 is divisible by 5 so you now have all prime factors whose product is 100

2x = 15 (subtract 1 on both sides)

x = 7.5 (divide 2 om both sides)

Since 7.5 is not an integer, (a) is No.

However 7.5 is rational, therefore (b) is Yes.

Find the inequality represented by the graph.

Answers

Answer:

[tex]y<-\frac{4}{3}x+5[/tex]

Step-by-step explanation:

Since, the given line in the graph is a dotted, line will represent an inequality with no sign of equal to (=).

Since, the shaded area is below the dotted line, inequality will have the sign less than (<).

Therefore, equation of the inequality will be in the form of,

y < mx + b

Here, m = slope of the line

b = y-intercept

Slope of the line passing through two points (0, 5) and (3, 1),

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{5-1}{0-3}[/tex]

   = [tex]-\frac{4}{3}[/tex]

Y-intercept (at x = 0),

b = 5

Therefore, equation of the inequality will be,

[tex]y<-\frac{4}{3}x+5[/tex]
