A line has slope −1. It passes through the point Q(2, −n) and R(4, −3). What is the value of n?

Answer: it will take 40 sections the course to accommodate all the students

Step-by-step explanation:

Given that;

434 freshmen, 883 sophomores and 43 juniors are enrolled

total number of students enrolled = (434 + 883 + 43) = 1360

number of student in one section = 34

now

number of sections of an introductory algorithms course needed to be scheduled to accommodate all these students will be;

Total number of section = total number of students enrolled / number of student in one section

so we substitute

Total number of section = 1360 / 34

Total number of section = 40

Therefore it will take 40 sections the course to accommodate all the students

Step-by-step explanation:

Answer:

k=3

Step-by-step explanation:

Answer:

k = 3

Step-by-step explanation:

step 1: simplify both sides of the equation

([tex]\frac{1}{3}[/tex]) (9k) + ([tex]\frac{1}{3}[/tex]) (3) = (-2) (k) + (-2) (-8) (distribute)

3k + 1 = -2k +16

step 2: add 2k to both sides

3k + 1 + 2k =-2k + 16 + 2k

5k + 1 = 16

step 3: subtract 1 from both sides

5k + 1 - 1 = 16 - 1

5k = 15

step 4: divide both sides by 5

[tex]\frac{5k}{5}[/tex] = [tex]\frac{15}{5}[/tex]

k = 3

Answer:

25

Step-by-step explanation:

1 cup has 8 ounces. if he has 3 then that's 24 ounces. He has one more so it's 25.

There are two approaches to this question.

Approach 1:

We can compute the slope of a line by calculating its mean variation, the rise over run. Mathematicaly:

[tex]a=\frac{\Delta y}{\Delta x}[/tex]

The two points we have are [tex]P1 = (1,3)[/tex] and[tex]P2 = (4,3)[/tex]. Plugging the values into the expression we get

[tex]a=\frac{3-3}{4-1} \\a=0[/tex]

Therefore, the slope of the line is zero.

Approach 2:

The slope of the line is given by the angle [tex]\alpha[/tex] it makes with the X axis, in other words,

[tex]a = tan(\alpha)[/tex]

Note that the angle the line makes is exaclty zero. Therefore:

[tex]a= tan(0)\\a=0[/tex]

Again, we get that the slope of the line is zero.

In general, the slope of any horizontal line will always be zero.

Answer:

x = 3

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, that is

DE = AB , substitute values

6x - 7 = 11 ( add 7 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3

Answer:

35

Step-by-step explanation:

Answer:

c and d

Step-by-step explanation

cause they can never intersect

Answer: b

Step-by-step explanation:

Cuz is a negative get in absolute value it always comes out positive

And it says below 0-9=-9

Answer:

Step-by-step explanation:

__________________________________________________________

B is the answer because,

if the negative sign is not inside the "brackets," then the number will still be negative.

__________________________________________________________

But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.

__________________________________________________________

Here are the reasons why the rest are wrong.

__________________________________________________________

A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.

__________________________________________________________

C is not correct because it is plainly not correct in itself.

__________________________________________________________

D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

Complete question :

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.

1. State the appropriate null and alternate hypotheses.

2. Compute the P-value.

Answer:

H0 : p = 0.5

H1 : p < 0.5

P value = 0.200454

Step-by-step explanation:

Given that :

Claim : Less than half internet users have posted photos or videos online.

Sample Proportion (p) = 865 / 1765 = 0.4900

The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.

The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;

P = 0.5

q = 1 - 0.5 = 0.5

The test statistic :

Z = p - p0 / sqrt(p0 * (q/n))

Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))

Z = - 0.01 / sqrt(0.5 *0.0002832)

Z = - 0.01 / sqrt(0.0001416)

Z = - 0.01 / 0.0119013

Z = - 0.8402443

The corresponding p value from the z statistic score at α = 0.01

= 0.200454

Answer:

k= 1 /15 x^3

Step-by-step explanation:

4/3 x 3/4 = 5k

5k= 1 /3 x^3

k= 1 /15 x^3

The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.

To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.

Multiplying the fractions on the left side:

(4/3) × (3/4) = 12/12 = 1

Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.

Dividing both sides of the equation by 5:

1/5 = k

Hence, the value of k in the given equation is 1/5.

Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5
