Answer:

GCF=X

FACTOR OUT X(5X+2)=0

X1=0 AND X2=-2/5

Step-by-step explanation:

The GCF is x . So when we factor it out we get

GCF =x

Factor out  x (5x+2)=0

x1=0 and x2=-2/5

Answer:

65

Step-by-step explanation:

Answer:

x = 12

m∠A = 104º

m∠B = 32º

m∠C = 44º

shortest side = B

middle side = C

longest side = A

Step-by-step explanation:

Recall that all angles in a triangle add up to 180º. Also recall that the side opposite largest angle is the longest side, and vice versa for the side opposite the smallest angle.

Complete question :

At a certain school, 25% of the students wear a watch and 30% wear a bracelet. 60% of the students wear neither a watch nor a bracelet.

a) One of the students is chosen at random. What is the probability that this student is wearing a watch or a bracelet?

b) What is the probability that this student is wearing both a watch and a bracelet?

Answer:

0.40 ; 0.15

Step-by-step explanation:

Let :

w = watch

b = bracelet

P(W) = 0.25

P(B) = 0.3

P(either a watch or a bracelet) = P(WuB)

P(neither a watch nor a bracelet) = 1 - P(WuB)

1 - P(WuB) = 0.6

a.) probability that student is wearing a watch or a bracelet = P(WuB)

P(neither a watch nor a bracelet) = 1 - P(WuB)

0.6 = 1 - P(WnB)

P(WnB) = 1 - 0.6

P(WnB) = 0.4

B.) probability that student is wearing both a watch and a bracelet : P(WnB)

Using the probability relation :

P(WuB) = P(W) + P(B) - P(WnB)

0.4 = 0.25 + 0.30 - P(WnB)

0.4 = 0.55 - P(WnB)

P(WnB) = 0.55 - 0.40

P(WnB) = 0.15

Step-by-step explanation:

5÷ 6

Answer:

what????????????????

Answer:

Probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]

Step-by-step explanation:

According to the classical approach to assigning probability, if an experiment has [tex]n[/tex] simple outcomes, this method  would assign a probability of [tex]\frac{1}{n}[/tex] to each outcome. In  other words, each outcome is assumed to have an equal  probability of occurrence.

So, probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]

Answer:

h+5=(6y)-8

Step-by-step explanation:

The sum is addition. So it wants you to add h and 5 on one side. Do 6 and y in parentheses on the other side and it wants you to subtract 8 from what you got from 6 times y.

Hope this helped!!

Answer:

A

Step-by-step explanation:

i think because it would equal to a logical number and estimation for the total cost (total for that sum is 83)

Hey there!

The answer to your question is D.) After coupons, the game is $2.25 cheaper at Techno Hut

First, we will solve for the price of Techno Hut's game. Let's find the amount of the discount:

0.10 x 40

4

Then, we take the discount off the price:

40 - 4 = 36

The price of the game at Techno Hut is $36

Next, we find the price of the game at Gamer World. Let's find the amount of the discount:

0.15 x 45

6.75

Then, we take the discount off the price:

45 - 6.75 = 38.25

The price of the game at Gamer World is 38.25

Therefore, Techno Hut is cheaper.

Hope it helps! Good luck and have a great day!

(-1 1/2,3

Step-by-step explanation:

Answer:

(-1 1/2,3)

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

5+5(9b - 7)

FIRST CASE (JUST EVALUATION)

Given the expression

[tex]5+5\left(9b-7\right)[/tex]

[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac[/tex]

[tex]5+5\left(9b-7\right)=5+5\cdot \:9b-5\cdot \:7[/tex]

                     [tex]=5+45b-35[/tex]

                     [tex]= 45b - 30[/tex]

Therefore, we conclude that:

[tex]5+5\left(9b-7\right)=45b-30[/tex]

SECOND CASE (Finding the value of b)

Assuming we have to determine the value of b

[tex]5+5(9b - 7) = 0[/tex]

As we have determined

[tex]5+5\left(9b-7\right)=45b-30[/tex]

so substituting [tex]5+5\left(9b-7\right)=45b-30[/tex] in the equation

[tex]45b-30 = 0[/tex]

Add 30 to both sides

[tex]45b-30+30=0+30[/tex]

Simplify

[tex]45b=30[/tex]

Divide both sides by 45

[tex]\frac{45b}{45}=\frac{30}{45}[/tex]

Simplify

[tex]b=\frac{2}{3}[/tex]

Therefore, the value of b = 2/3

Answer:

The value of x is -2 and 2.

Step-by-step explanation:

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :

x² - 3x - 1 = -3x + 3

x² - 3x - 1 + 3x - 3 = 0

x² - 4 = 0

Next, you have to factorize and solve it :

x² - 4 = 0

x² + 2x - 2x - 4 = 0

x(x + 2) - 2(x + 2) = 0

(x + 2)(x - 2) = 0

x + 2 = 0

x = -2

x - 2 = 0

x = 2

Answer:

There is sufficient evidence at 0.05 significant level to support company's claim.

Step-by-step explanation:

We have these informations from the question

n = 1400

P^ = 31% = 0.31

Alpha level = 5% = 0.05

Then we come up with the hypothesis

H0: P = 0.28

H1: P>0.28

From here we calculate the test statistic

z = p^ - p/√pq/n

P = 0.28

q = 1-0.28

= 0.72

z = 0.31-0.28/√(0.31*0.72)/1400

= 0.03/√0.0001594

= 0.03/0.012

= 2.5

Then we have a p value = 0.00621

The p value is less than significance level

0.00621<0.05

So the null hypothesis is rejected.

We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.

Answer:

h= 6.8

Step-by-step explanation:

Answer: the required equation is 5x - 6y + 5z = 7

Step-by-step explanation:

Given that;

points : (-1, 1, -5) and (4, -5, 0).

mid point : ( [(-1+4)/2], [(1-5)/2], [(-5+0)/2]

⇒ midpoint : ( 3/2, -2, -5/2 )  

                        x₀    y₀    z₀

Direction vector n = [4-(-1)], [ -5 - 1], [ 0 - (-5)]

⇒ Direction vector n = < 5, -6, 5 >

General equation plane : n(x-x₀, y-y₀, z-z₀) = 0

so we substitute

⇒ (5, -6, 5) (x-3/2, y-(-2), z-(-5/2) ) = 0

⇒ (5, -6, 5) (x - 3/2, y + 2, z + 5/2) ) = 0

⇒ 5(x - 3/2) - 6(y + 2 ) + 5(z + 5/2) = 0

⇒ 5x - 15/2 - 6y - 12 + 5z + 25/2 = 0

⇒ 5x - 6y + 5z = 15/2 + 12 - 25/2

⇒ 5x - 6y + 5z = 7

Therefore, the required equation is 5x - 6y + 5z = 7

Answer:

f^-1(x) =  (2x + 4) / 3

Step-by-step explanation:

- switch 'y' with 'x'

x = 3/2y - 2

- solve for 'y'

x + 2 = 3/2y

- multiply each side by 2

y = (2x + 4) / 3
