2 more than the product of 3 and a number is -10.

Answers

Answer:

-4

Step-by-step explanation:

2 more than the product of 3 and a number is -10 can be written as 3x+2=-10.

we can take this equation and solve it, first subtracting 2 from both sides to get 3x=-12.

now we divide both sides by 3 to get x=-4, so the answer is -4.

Answer:

C x>3

Step-by-step explanation:

Answer:

The answer is (C) x>3

Step-by-step explanation:

Well first just solve it normally like an equation, ignore the sign for now.

-5x+20<5

Isolate the x so we subtract 20 on both sides

-5x<-15

Now divide by -5 to isolate 5 from X

x>3

You switch the sign because whenever you divide or multiply a negative number to isolate x, the sign reverses.

A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.

The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?

Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.

Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.

which table shows a relationship that is directly proportional?

a b c d?

Answers

Answer:

A is the answer because...

Step-by-step explanation:

Let's narrow it down, so it is not D because 8/2=4 but 64/4=16, so already they don't share a slope. It is not B because the numbers don't work together like they should, since we are trying to prove proportionality. It is not C because we are not trying to square the numbers but find a similarity between the numbers, the same slope I mean. So that leaves A which has the slope of 2, test it out now. 0 and 0 are the same, 4/2=2, 8/4=2, 12/6=2. So now you know that A is the correct answer.

Hope you understand! :)

Ellie wanted to build a fence around her rectangular garden. The garden is 10 ft by 20 ft. A) What is the perimeter of the garden in feet?

Answers

Answer:

60 feet

Step-by-step explanation:

Perimeter is the sum of the four sides of a rectangle

the formula for the perimeter of a rectangle = 2 x (length + breadth)

2 x (10 + 20)

2 x (30)

= 60 feet

Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet

The value of y is directly proportional to the value of x If y=81 when x=54, what is the value of y when x=38

Answers

Answer:

y = 57

Step-by-step explanation:

y α x

y = kx ; k = Constant of proportionality

81 = k* 54

k = 81/54

k = 1.5

Value of y when x = 38

y = kx

y = 1.5 * 38

y = 57

Hence, y = 57 when x = 38

The circumference of a circular mirror is 31.4 cm. What is the area of the circular mirror in square centimeters? Use pi = 3.14 .

Answers

Answer : AREA OF A CIRCLE = PIR2 ( PI ×R ×R )

N.B = R MEANS RADIUS.

GIVEN THE CIRCUMFERENCE, WE WILL USE THE CIRCUMFERENCE TO FIND THE RADIUS.

FORMULA FOR FINDING RADIUS = CIRCUMFERENCE ÷ 2 × 3.142.

SO THAT IS : 31.4 ÷ 6.284 = 4.9.

ROUND UP : 5.

SO THE RADIUS IS 5. NOW WE CAN FINDING THE AREA. 3.14×5×5 = 78.5 . Say thanks Nique.
