What is the slope-intercept equation of the line below? ​

Answer:

2

Step-by-step explanation:

Blue pants: 5

Zipper pants: 6

total amount of pants (blue, zipper or both): 9

to find the pants that have both qualities, we need to find the difference between the total amount of pants and the sum of the blue and zipper pants:

sum of blue and zipper pants: 5 + 6 = 11

you can tell that there is a difference of

11 - 9 = 2 pants

this means that these 2 pants belong to both categories (blue and with a zipper). Thus there are 2 pants that are blue and have a zipper

Answer:

The 32 electricians are expected to finish the job in 27 days.

Step-by-step explanation:

In this case we can apply a rule of three to calculate the time it'll take for the 32 electricians to finish the job. This is done below:

24 electricians -> 36 days

32 electricians -> x days

We have to be careful here, since the variables are inversely proportional, since if there are more electricians working on the same job, we expect the job to be finished in fewer days, therefore we need to invert one of the fractions as shown below:

[tex]\frac{24}{32} = \frac{x}{36}\\32*x = 36*24\\x = \frac{864}{32}\\x = 27[/tex]

The 32 electricians are expected to finish the job in 27 days.

Step-by-step explanation:

The trip takes 2 hours

Stopping every half hour means stopping at 30 minutes, 1 hour, 1.5 hours

We would not stop at 2 hours because we would be done.

One the number line R means rest stops

200 Km /4 means at 50 km, 100 km 150 km and 200 km

The rest stops are at 50 km 100 km 150 km  (the one at 200 is at the end of the trip so it is not a rest stop

We have to stop for gas 3/4 of the way

200 *3/4 = 150 km

We will stop for gas at a rest stop at 150 km

Answers and Step-by-step explanations:

(a)

We want to find where to stop, so let's calculate the distances between the different rest points.

This is a distance-rate-time problem, so we need to use the equation d = rt, where d is the distance, r is the rate, and t is the time. Here, d = 200 km and t = 2 hours. So:

200 = r * 2

r = 100

Your speed is 100 km/hr. Now, you plan on stopping every half hour. We know that you drive 100 km in 1 hour, so that means you drive 100/2 = 50 km in half an hour. So, we want to draw a number line where every 50 km, there's a rest stop (red on attachment).

See attachment.

(b) We need to get gas at Fort MacLeod, which is 3/4 of the way to Lethbridge. The total distance is 200 km, so 3/4 of that will be:

(3/4) * 200 = 600 / 4 = 150 km

So, mark the place that is 150 km (blue on attachment).

See attachment.

Note that the green simply represents your entire trip from Calgary (start) to Lethbridge (end).

Answer:

14 and 17

Step-by-step explanation:

x+y=41

y=2x-1

x+(2x-1)=41

3x-1=41

3x=42

x=14

y=2(14)-1=27

Step-by-step explanation:

Step 1:  Make a system of equation

The sum of two numbers is 41

    x        +        y        =        41

The larger number is one less than twice the smaller number.

    x                =                2y               -                1

Step 2:  Substitute x from the second equation into the first

[tex]x + y = 41[/tex]

[tex](2y - 1) + y = 41[/tex]

[tex]3y - 1+ 1 = 41 + 1[/tex]

[tex]3y/3 = 42 / 3[/tex]

[tex]y = 14[/tex]

Step 3:  Substitute y into the second equation

[tex]x = 2y - 1[/tex]

[tex]x = 2(14) - 1[/tex]

[tex]x = 28 - 1[/tex]

[tex]x = 27[/tex]

Answer:  [tex]x = 27, y = 14[/tex]

Answer:

15 students (30% of the students in class) scores a 95 on a quiz.

Therefore the total number of students (100% of the students) in class is:

N = 15 x 100/30 = 50 (students)

(This calculation is inferred from a ratio that 15/N = 30/100).

Denote the number of students who scored a 95 on a quiz is a, the total number of students in class is b.

Then the equation that related a and b is:

b = (100/30) x a

Answer:

100 degrees

Step-by-step explanation:

The angle x is opposite the angle that is 100 degrees.

Since they are opposite each other, they are vertical angles.

This means that they are congruent, or equal to each other.

Therefore,

x=100

x is 100 degrees

Answer:

B

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD

here, x = 130, mean = 120 and SD = 10

Substituting these values

z-score = (130-120)/10 = 10/10 = 1

So the probability we want to calculate is;

P(z ≥ 1) = 1 - P(z <1)

From standard score table, P(z <1) = 0.15866

P(z ≥ 1) = 1-0.15866 = 0.84134

I will answer in English.

We have a deck of 52 cards, and we want to find the probability of drawing, at random, a 1.

We have 4 1's in the deck, one for spades, one for hearts, one for diamonds and one for clovers.

So the probability can be calculated as the quotient between the total number of 1's in the deck and the total number of cards in the deck, this is:

P = 4/52 = 0.077

Answer:

One solution

Step-by-step explanation:

–5n = 2 − 6n

–5n +6n = 2 − 6n + 6n (Addition Property of Equality)

n = 2

There is one solution to this equation. The value of 'n' is 2.

Answer:

n = 2 thus 1 solution

Step-by-step explanation:

Solve for n:

-5 n = 2 - 6 n

Add 6 n to both sides:

6 n - 5 n = (6 n - 6 n) + 2

6 n - 6 n = 0:

6 n - 5 n = 2

6 n - 5 n = n:

Answer: n = 2

Answer:

It is B, I got it right on edman!

Step-by-step explanation:

The correct ways can the roles be assigned is  84 ways.

To find ways can the roles be assigned.

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Given That:

Total individuals = 9

Available roles = 5

First, it'll be assumed that no two individual shares a role and no single individual takes two roles.

Having said this, the number of ways the roles can be assigned can be calculated using the combination formula  as follows.

ⁿCr = C(n,r)

Where n represents the total individuals

n = 9

r represents the available roles

r = 5

So,

ⁿCr = C(n,r)

⁹C₆ = C(9,6)

⁹C₆= 9!/((9-6)!*6!)

⁹C₆ = 9!/(3!*6!)

⁹C₆ = (9 * 8 * 7 * 6!)/(6! * 3 * 2 * 1)

⁹C₆ = (9 * 8 * 7)/(3 * 2 * 1)

⁹C₆ = 504/6

⁹C₆ = 84

Hence, 9 roles can be assigned to 5 people in 84 ways.

Step-by-step explanation:

The circle is a flat surface or area limited or closed by a circumference. It is a two-dimensional figure and is formed by making a curve where it will always have the same distance to the center. Its area can be calculated using the following formula:

[tex]A=\pi r^2\\\\Where:\\\\r=radius[/tex]

Step-by-step explanation:

Answer:

t = 0.77

Step-by-step explanation:

D(t) = 50 - 23 sin(π(t + 0.23))

The value of the sine function has a maximum of -1 and a minimum of 1.

The average value of the sine function is 0.

At maximum sine value:

D(t) = 50 - 23(1) = 50 - 23 = 27

At minimum sine value:

D(t) = 50 - 23(-1) = 50 + 23 = 73

At average sine value of 0:

D(t) = 50 - 23(0) = 50 - 0 = 50

The average depth of the waves is 50 cm.

Now we need to find at what time, t, that occurs.

D(t) = 50 - 23 sin(π(t + 0.23)) = 50

50 - 23 sin(π(t + 0.23)) = 50

-23 sin(π(t + 0.23)) = 0

sin(π(t + 0.23)) = 0

The value of the sine is 0 at 0, π, 2π, ..., nπ

π(t + 0.23) = nπ

t + 0.23 = n

t = n - 0.23

n is all integers, but here we are concerned with the first occurrence after time equals zero, so we want n = 1.

t = 1 - 0.23

t = 0.77
