Answer: 648

Step-by-step explanation:

HOPE THIS IS RIGHT

Answer:

The answer is D because it is closer to zero so it is greater in value. For example if the number is further away from zero (and is negative) the value is less but if it’s closer it is greater and in positive numbers the rules are opposite

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Theoretically it is 120/8=15

Answer:

since g:B→C is onto

suppose z∈C,there exists a pre-image in B

Let the pre-image be y

Hence y∈B such that g(y)=z

similarly f:A→B is onto

suppose y∈B,there exists a pre-image in A

Let the pre-image be x

Hence x∈A such that f(x)=y

Now gof(x)=g(f(x))=g(y)=z

So for every x in A,there is an image z in C

Answer:

30, 35 and 40

Step-by-step explanation:

The given sequence 10, 15, 20, 25... is an arithmetic sequence

nth term of an arithmetic sequence Tn = a +(n-1)d

a is the first term = 10

d is the common difference = 15-10 = 20-15 = 5

n is the number of terms

For the 5th term

T5 = 10 + (5-1)*5

T5 = 10+4(5)

T5 = 10+20

T5 = 30

For the 6th term

T5 = 10 + (6-1)*5

T6 = 10+5(5)

T6 = 10+25

T6 = 35

For the 7th term

T7 = 10 + (7-1)*5

T7 = 10+6(5)

T7 = 10+30

T7 = 40

Hence the next 3 terms are 30, 35 and 40

Answer:

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average price for a gallon of gasoline in France is $5.54. The standard deviation is $.25.

This means that [tex]\mu = 5.54, \sigma = 0.25[/tex]

What is the probability that a randomly selected gas station in France charges more than $5.30 per gallon?

This is 1 subtracted by the pvalue of Z when X = 5.30. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5.3 - 5.54}{0.25}[/tex]

[tex]Z = -0.96[/tex]

[tex]Z = -0.96[/tex] has a pvalue of 0.1685

1 - 0.1685 = 0.8315

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Answer:

The answer is 36 and 225.

Step-by-step explanation:

36 is the square number of 6.

225 is the square number of 15.

Answer:

mean: 14.64

mode: 15

median: 15

Answer:

x=-2,-4 is your answer

x²+6x+8=0

doing middle term factorization

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

either

x=-4

or

x=-2

Answer:

7 hours and 15 minutes.

Step-by-step explanation:

Draw a timeline for this question.

8.30 + 7 hours = 3.30pm or 15 30

3.30 + 0.15 minutes = 3.45 or 15 45

7 hours + 0.15 minutes = 7 hours and 15 minutes.

Answer:

You should study hard and look through the test first to answer the ones you do know and then go back to the ones you don't know. Also if you use any methods or anything related to help with math try to use those through. Therefore try your best and just prepare for it, and always have supplies.

That is True.

Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as   x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!

Answer:

49 is your answer

Step-by-step explanation:

let's do b-pemdas

brackets

parentheses

e(I forgot the name for it but it's basically a small number next to the big number)

Multiply

Divide

Add

Subtract

you do the equation in that order

so

2+8•7-(3^2)

we focus on (3^2)

that's 3•3 which equals to 9

so now the equation is

2+8•7-9

Now we focus on 8•7 which equals to 56

the equation now looks like

2+56-9

you then add 56 to 2 which equals to 58 and then subtract 9 from it so it should look like this

2+56=58

58-9= 49

and 49 is your answer

hope this help!!!

if you would give me brainliest that would help a lot!!

Step-by-step explanation:

Here is 4 divided by 3/5 displayed mathematically

4

 ÷    

3

5

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

4 x 5

3

 =    

20

Thus, the answer to 4 divided by 3/5 in fraction form is:

20

To make the answer to 4 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

20 / 3 = 6.67

Answer:

4 ÷ 3/5 = 6.66666666667

Answer:

(0, 4 ) and (2, - 4 )

Step-by-step explanation:

(2)

3x + 4y = 16 → (1)

- 3x + 2y = 8 → (2)

Adding (1) and (2) term by term will eliminate the x- term

0 + 6y = 24

6y = 24 ( divide both sides by 6 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(4) = 16

3x + 16 = 16 ( subtract 16 from both sides )

3x = 0 , then

x = 0

solution is (0, 4 )

(3)

2x - 4y = 20 → (1)

5x + 4y = - 6 → (2)

Adding (1) and (2) term by term will eliminate the y- term

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (2)

5(2) + 4y = - 6

10 + 4y = - 6 ( subtract 10 from both sides )

4y = - 16 ( divide both sides by 4 )

y = - 4

solution is (2, - 4 )

Answer:

The maximum height attained by the ball is of 180 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

In this question:

We have that:

[tex]s(t) = -16t^2 + 48t + 144[/tex]

Which is a quadratic equation with [tex]a = -16, b = 48, c = 144[/tex].

The maximum height is the value of s, which is the output, at the vertex. So

[tex]\Delta = b^2-4ac = 48^2 - 4(-16)(144) = 11520[/tex]

[tex]s_{v} = -\frac{11520}{4(-16)} = \frac{11520}{64} = 180[/tex]

The maximum height attained by the ball is of 180 feet.

Answer:

Step-by-step explanation:

let r be radius of inner circle.

2πr=25.12

πr=25.12/2=12.56

3.14r=25.12

r=12.56/3.14=4

outer radius R=4+4=8 mm

reqd. area=πR²-πr²=π(R²-r²)=3.14(8²-4²)=3.14(64-16)=3.14×48= 150.72 mm²
