Answer:

I think the answer is 2

Step-by-step explanation:

I it is perpendicular to y=2x-3 then the x value has to be -1 meaning that the x value has to be -2x

so we have Y=-2x+c

We know the Y value is -3 from the co ordinates (0,-3)

so now we have -3=-2x+c

we also know x=0 from the co-ordinates (0,-3)

so we now have -3=-2*0+c

-3=0+c

to make the equation work c has to be -3 meaning that we now have

-3=0-3 which is

Y=-2x-3

I'm sorry if any of these are wrong I didn't get to check them over.

Step-by-step explanation:

I will be substituting "a number" with the variable x.

1. Four more than twice a number is 8.

2x+4 = 8

2x = 4

x = 2

2. Three more than four times a number is 15.

4x+3 = 15

4x = 12

x = 3

3. Five less than twice a number is 7.

2x-5 = 7

2x = 12

x = 6

4. One less than four times a number is 11.

4x-1 = 11

4x = 12

x = 3

5. Seven more than the quotient of a number and 2 is 10.

(x/2)+7 = 10

(x/2) = 3

x = 6

6. Six less than six times a number is 12.

6x-6 = 12

6x = 18

x = 3

7. Five less than the quotient of a number and 3 is -7.

(x/3)-5 = -7

x/3 = -2

x = -6

8. Seven more than twice a number is 1.

2x+7 = 1

2x = -6

x = -3

9. The difference between 5 times a number and 3 is 12.

5x-3 = 12

5x = 15

x = 3

10. Nine more than 3 times a number is -6.

3x+9 = -6

3x = -15

x = -5

11. Nine more than the quotient of a number and 4 is 12.

(x/4)+9 = 12

x/4 = 3

x = 12

12. Four less than the quotient of a number and 3 is -10.

(x/3)-4 = -10

x/3 = -6

x = -18

13. Nine less than six times a number is -15.

6x-9 = -15

6x = -6

x = -1

Answer:

The correct option is:

(a) There is sufficient sample evidence for the program's claim to be considered correct.

Step-by-step explanation:

The hypothesis can be defined as follows:

[tex]H_{0}:\mu\geq 4\\\\H_{a}:\mu< 4[/tex]

A random sample of n = 50 students is selected.

The significance level of the test is, α = 0.05.

The degrees of freedom are:

df = n - 1

   = 50 - 1

   = 49

Compute the critical value as follows:

[tex]t_{\alpha,\ (n-1)}=t_{0.05,\ 49}[/tex]

             [tex]=t_{0.05, 60}\\\\=-1.671[/tex]

Use the t-table.

Decision rule:

If the calculate value of the test statistic is less than the critical value then the null hypothesis will be rejected.

The calculate value of the test statistic is, t = -1.69.

[tex]cal.t=-1.69<t_{0.05, 49}=-1.671[/tex]

The null hypothesis will be rejected at 5% level of significance.

The correct option is:

(a) There is sufficient sample evidence for the program's claim to be considered correct.

Answer:

1 7 21 35 35 21 7 1

Step-by-step explanation:

Pascal triangle is a mathematical expression that can be used to expand questions involving bracket, especially of high degree/ power. Example: [tex](a + b)^{9}[/tex] etc

For the given question, the Pascal triangle for the expansion is: 1 7 21 35 35 21 7 1

So that,

[tex](2x^{3}+3y^{2}) ^{7}[/tex] = 1.[tex](2x^{3}) ^{7}[/tex] + 7.[tex](2x^{3}) ^{6}[/tex].[tex]3y^{2}[/tex]  + 21. [tex](2x^{3}) ^{5}[/tex].[tex](3y^{2}) ^{2}[/tex] + 35.[tex](2x^{3}) ^{4}[/tex].[tex](3y^{2}) ^{3}[/tex] + 35. [tex](2x^{3}) ^{3}[/tex].[tex](3y^{2}) ^{4}[/tex] + 21.

   = 128[tex]x^{21}[/tex] + 1344[tex]x^{18}[/tex][tex]y^{2}[/tex] +  6048[tex]x^{15}[/tex][tex]y^{4}[/tex] + 15120[tex]x^{12}[/tex][tex]y^{6}[/tex] + 22680[tex]x^{9}[/tex][tex]y^{8}[/tex] + 20412[tex]x^{6}[/tex][tex]y^{10}[/tex] + 10206[tex]x^{3}[/tex][tex]y^{12}[/tex] + 2187[tex]y^{14}[/tex]

Therefore;

[tex](2x^{3}+3y^{2}) ^{7}[/tex] = 128[tex]x^{21}[/tex] + 1344[tex]x^{18}[/tex][tex]y^{2}[/tex] +  6048[tex]x^{15}[/tex][tex]y^{4}[/tex] + 15120[tex]x^{12}[/tex][tex]y^{6}[/tex] + 22680[tex]x^{9}[/tex][tex]y^{8}[/tex] + 20412[tex]x^{6}[/tex][tex]y^{10}[/tex] + 10206[tex]x^{3}[/tex][tex]y^{12}[/tex] + 2187[tex]y^{14}[/tex]

Step-by-step explanation:

Answer:

92.044

Step-by-step explanation:

The variance = 36

σ² = 36 = 6

The probability that x is less than 88 is equal to 0.25

So probability of (x<z) = 0.25

From the z table, z = -0.674

Using the z formula,

z = x-u/σ

Z = -0.674

X = 88

σ = 6

When we insert these formula we have:

-0.674 = 88 - u/6

6 x -0.674 = 88- u

-4.044 = 88 - u

92.044 = u

Therefore from the calculations above the mean of X is 92.044 and it is approximately 92.

Answer:

4:4

Step-by-step explanation:

3:3 can be simplified to 1:1 ( divide by 3) and then to 4:4( multiply by 4)

Hope this helps :D please mark brainliest if correct

The ratio 3:3 reduces to 1:1 when we divide both parts by 3.

Then multiply both parts of 1:1 by 4 to get to 4:4

note how 3/3 = 1 and 4/4 = 1, which helps show 3/3 = 4/4, consequently leading to 3:3 and 4:4 being equivalent ratios.

In general, the ratio 3:3 is equivalent to anything of the form x:x where x is any number you want. So for instance, if x = 7, then 3:3 is equivalent to 7:7

Answer:

B

Step-by-step explanation:

Purple-70/300=7/30

The equivalent ratio to the ratio 30 : 40 after dividing by 10 will be;

⇒ 3 : 4

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

The ratio is,

⇒ 30 : 40

Now,

When we dividing both sides by 10, we get;

Since, The ratio is;

⇒ 30 : 40

It can be written as;

⇒ 30 / 40

After dividing by 10, we get;

⇒ 30 / 40

⇒ (30 ÷ 10) / (40 ÷ 10)

⇒ 3 / 4

⇒ 3 : 4

Therefore,

The equivalent ratio to the ratio 30 : 40 after dividing by 10 will be;

⇒ 3 : 4

Answer:

56

Step-by-step explanation:

(24+4)x2=28x2=56

Answer:

56

Step-by-step explanation:

First things first we need to make into an understandable equation. Remember that sum means we will be adding 24 and 4. As for doubled that means that 24+4 will be multiplied by 2 so the equation should turn out like this...

[tex]x=2(24+4)[/tex]

Once we have the equation set up we can solve it...

[tex]x=2(24+4)\\x= 48+8\\x=56[/tex]

So the sum of 24 and 4 doubled is 56.

Answer:

Step-by-step explanation:

Answer:

4(5 - 7x) = 6 - 12

20-28x=6-12x

Subtract 20 from both sides

20-28x-20=6-12x-20

Simplify

-28x=-12x-14

Add 12x to both sides

-28+12x=-12x=-12x-14+12x

Simplify

-16x=-14

Divide both sides by -16

-16/-16 = -14/-16

7/8= 0.875

Part A

---------------------------------

Work Shown:

The universal set here is U = {2,3,4,5,6,7,8,9} so we're listing all the integers between 2 and 9. We don't include 1 or 10 since n is larger than 1, and smaller than 10.

P = even numbers less than 7, subset of U

P = {2,4,6,8}

P ' = {3,5,7,9}

Note how the set P' is the set of everything in U that is not in set P. It's the opposite of set P. We call this the complement of set P.

Q = prime numbers less than 10, subset of U

Q = {2,3,5,7}

Q ' = {4,6,8,9}

Applying the union set operation on the sets P' and Q' leads to

P' u Q' = {3,5,7,9,     4,6,8,9}

All I did was combine the two sets of numbers under one umbrella. From here we toss out the duplicate entry of 9. This next step is optional, but sorting the values is standard convention.

Doing all this leads to

P' u Q' = {3,4,5,6,7,8,9}

This set represents all the values that are in set P' or in set Q' or both.

=======================================================

Part B

---------------------------------

Work Shown:

Now we're looking at the intersection of sets P' and Q'

List out those sets

P ' = {3,5,7,9}

Q ' = {4,6,8,9}

We see that only the value 9 is in common

Therefore,

P' n Q' = {9}

=======================================================

Part C

Answer:

(P' n Q')' = {2,3,4,5,6,7,8}

---------------------------------

Work Shown:

You start with the result from part B. Then you erase that item (9) from the universal set. Everything in this answer set is not found in the set {9}

Put another way: we're finding the complement or opposite of P' n Q'

=======================================================

Part D

---------------------------------

Work Shown:

P = {2,4,6,8}

Q = {2,3,5,7}

P u Q = {2,3,4,5,6,7,8}

Everything in set P u Q is either found in P, Q, or both. Any duplicates are tossed out.

Take the opposite of this to get

(P u Q)' = {9}

It is not a coincidence we get the same result as part B. It turns out that the two equations are true for any two sets P and Q
