(5,-6) and (4,3) find the slope

Answer:

B. 88.8

Step-by-step explanation:

let x represent class y

(x+71.2)/2=80   multiply each side by 2

x+71.2=160      subtract 71.2 by both sides

x=88.8

or

trial an error

replace x with each of the numbers and see if it plugs in.

example:

(80.5+71.2)/2=80

151.7/2=80

75.85=80?

false. incorrect

another example:

(88.8+71.2)/2=80

160/2=80

80=80?

true. correct

Step-by-step explanation:

[tex](2c + 8) + (6c - 6) = 90 \\ 8c + 2 = 90 \\ 8c = 88 \\ c = \frac{88}{8} = 11[/tex]

The value of c is 11.

Two angles whose sum is 90° are called complementary angles.

We are given vertical adjacent complementary angles ;

2c + 8

6c - 6

The two angles form a 90 degree. thus  they add to 90

2c + 8 + 6c - 6= 90

Combine like terms;

8c + 2 = 90

Subtract 2 from each side

8c = 88

Divide by 8

c = 11

The value of c is 11.

Step-by-step explanation:

Tan = Opposite over Adjacent

[tex]tan(83)=\frac{7}{x}[/tex]

* multiply each side by x *

[tex]tan(83)*x=xtan(83)\\\frac{7}{x} =7\\xtan(83)=7[/tex]

* divide each side by tan(83) *

[tex]\frac{xtan(83)}{tan(83)} =x\\\frac{7}{tan(83)} =0.8594919263\\x=0.8594919263[/tex]

Answer:

b

Step-by-step explanation:

There are 2 sequences with a₁ = 47, b and d

The common difference of both is

(b)

d = a₂ - a1 = 29 - 47 = - 18

(d)

d = a₂ - a₁ = 65 - 47 = 18

The the sequence with first term 45 and common difference - 18 is b

The required sequence which has a first term equal to 47 and a common difference of -18 is {47, 29, 11, -7, …}. Option B is correct.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
An arithmetic sequence has a first term equal to 47 and a common difference of -18,
a = 47
d = -18

The sequence formed given as,
⇒ a, a + d, a + 2d, a + 3d
⇒ 47, 47 - 18, 47 + 2(-18), 47 + 3(-18)
⇒ 47 , 29, 11, -7 . . . . .

Thus, the above sequence matches the sequence given in option b.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

√16/25 = 4/5 = 0.8-> (4/5 x 4/5 = 16/25)

(2/5)^3 = 8/125  = 0.064

-(-0.3)^3 = 0.027 (an odd exponent mantains the same sign of the number and minus x minus = +)

-√169 = -13

-13 is a negative number so it is surely the smallest

2 is minor than 6 so we have that 0.027 is minor than 0.064

8 is major than 0, so 0.8 is the greatest number

we have

-√169 ; -(-0.3)^3 ; (2/5)^3 ; √16/25

Answer:

El precio de la falda es 50 €.

Step-by-step explanation:

Lo que sabemos:

[tex] F = 5 + B [/tex]   (1)

En donde F es por falda y B por blusa.

Si compras 6 faldas y 4 blusas y pagas 480 €:

[tex] 6F + 4B = 480 [/tex]  (2)

Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.

[tex] 6F + 4B = 480 [/tex]

[tex]6(5 + B) + 4B = 480[/tex]

[tex] 10B = 480 - 30 [/tex]

[tex]B = \frac{450}{10} = 45[/tex]  

Finalmente, el precio de la falda se puede encontar con la ecuación (1):

[tex]F = 5 + 45 = 50[/tex]

Por lo tanto, el precio de la falda es 50 €.

Answer:

B. 2

To find MAD, find the mean of the set, then find how far each number is from the mean. Next, find the mean of THAT set of numbers. Yea, I know it's a bit confusing... don't worry!

Find the mean of the set:

12 + 10 + 10 + 8 + 6 + 7 + 7 + 12

72

72 / 8

9

Find how far each number is from 9:

12 - 9 = 3

10 - 9 = 1

10 - 9 = 1

9 - 8 = 1

9 - 6 = 3

9 - 7 = 2

9 - 7 = 2

12 - 9 = 3

Find the mean of that number set:

{3, 1, 1, 1, 3, 2, 2, 3}

3 + 1 + 1 + 1 + 3 + 2 + 2 + 3

16

16 / 8

2

Answer:

It would be B. 8x3/5

Step-by-step explanation:

So when multiplying fractions, you multiply the denominator of one fraction by the denominator of the other. You then multiply the numerator of one fraction by the numerator of the other.

The 8, can be turned into fraction form by thinking of it as 8/1 x 3/5.

And thinking about how we do denominator x denominator, numerator x numerator, it will look like:

[tex]\frac{8*3}{1*5}[/tex]

There is one more thing we need to simplfy before we will get our answer.

When you multiply a number by 1, what do you get? The same exact number as before.

Sp tecnically, 1*5 would just be 5:

[tex]\frac{8*3}{5}[/tex]

This looks like answer b!

Answer:

a. at least 20%, when in fact, it is less than 20%.

Step-by-step explanation:

Type 1 Error is to reject null hypothesis when it is actually true.

Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.

In mathematics fewer than 20% means less than  20%.

So the null hypothesis is that less than 20 % students attended the show.

We have to reject this hypothesis .

We can reject this hypothesis when we assume that the % is greater than or equal to 20 %

At least  20% means greater than or equal to 20%.

So the best choice is option a.

at least 20%, when in fact, it is less than 20%.

Answer:

[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]

Step-by-step explanation:

The given equation is :

[tex]r=ht^2 -2vt-2c[/tex]

We need to solve the above equation for v.

Subtract ht² from both sides.

r-ht²= ht²-2vt-2c-ht²

r-ht² = -2vt-2c

Adding 2c both sides,

r-ht² +2c= -2vt-2c+2c

r-ht² +2c = -2vt

Dividing both sides by (-2t)

[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]

So, the value of v is equal to [tex]\dfrac{r-ht^2+2c}{-2t}[/tex].
