——————————-

8 seconds ÷ 8

=    6.375 meters

——————————

      1 second

6.375

Answer:

A) 1

B) 25

C) 0.007

D) 0.03

Step-by-step explanation:

A) 1 cm is 10mm so multiply the given number by ten to get the answer

B) 1m is 1000mm so divide the given number by one thousand to get the answer

B) 1kg is 1000g so divide the given number by one thousand to get the answer

C) One ml is 1000000 times smaller than 1kl so divide your number by 1000000 to get the answer

For every ginger cookie:

                                                      4:2

Step-by-step explanation:

When they ask what the prob that at most 3/4 people asked have a pet, they are asking what is the prob that 0, 1, 2, or 3 people answer yes. So you could calculate all 4 of those and then add them together.

However, in this case, since there's only 1 other possible outcome (all 4 have a pet), we could just calculate the prob of that and subtract it from 1 to get the prob of everything else happening.

We'll use the binomial distribution formula where n=4, k=4, and P=.6.

nCk * P^n * (1-P)^(n-k)4C4 * (.6)^4 * (.4)^0.1296

So the prob of at least 3 having pets = 1 - P(all 4 have pets) which is 1-.1296 = .8704.  You could double check this by calculating the prob of the other 4 outcomes and then adding them together.

The probability that at least 2 people have a cat is 0.522 or 52.2%.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

This is a problem that can be solved using the binomial probability formula, which gives the probability of getting exactly k successes (in this case, people with cats) out of n trials (in this case, people you ask) with a probability of success (in this case, having a cat) of p.

The formula is:

P(k) = (n choose k) × [tex]p^k \times (1-p)^{(n-k)}[/tex]

where (n choose k) is the binomial coefficient, which is equal to n! / (k! × (n-k)!).

For this problem, n = 5 (the number of people you ask), k = 2 (the number of people who have cats), and p = 0.3 (the probability of a person having a cat, according to the survey).

P(2) = (5 choose 2) × 0.3² × 0.7³

P(2) = 0.252

To find the probability of at least 2 people having a cat, we have to add up the probability of getting exactly 2, 3, 4, and 5 people having cats.

P(≥2) = P(2) + P(3) + P(4) + P(5)

Substituting the values we get:

P(≥2) = 0.252 + 0.189 + 0.072 + 0.009 = 0.522

So, the probability that at least 2 people have a cat is 0.522 or 52.2%.

Answer:

Step-by-step explanation:

Student who did not play Volleyball  = Students who play only hockey + students who don't play any game

= 5 + 3 = 8

Students who play hockey only = 5

Answer:

Step-by-step explanation:

1) a variable term contains a variable. If x is  a variable

5x is an example of a variable therm

2) a constant therm is not a variable

3 is an example

3) for example when a number multiply a sum or a difference between a constant and a variable

Example:

2(x-3) = 5(x+4)

4) one solution: only if x is equal to 0 the equation is true

5) no solution: the equation can’t be true for ever value of the variable

6) infinite solutions: the equation is ever true for every value of the variable

Answer:

46,213,300 km

Step-by-step explanation:

46,213,267

in the above number ;

7 = units

6 = tens

2 = hundred

3 = thousand

1 = ten thousand

2 = hundred thousand

6 = million

4 = 10 million

to round off to the nearest hundred, look at the number in the tens (6). If this number is greater than or equal to 5, add 1 to the hundreds unit, if this is not the case, add zero

because  6 is greater than 5, add one to the hundred value

= 46,213,300 km

Answer:

101/12

Step-by-step explanation:

3/4r-3 1/4=49/16

3 1/4=13/4

3/4r-13/4=49/16

3/4r=49/16+13/4

3/4r=49/16+52/16

3/4r=101/16

r=(101/16)/(3/4)

r=(101/16)(4/3)

r=101/12

Step-by-step explanation:

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Any feature increases when y-value should likewise be increased for the growth of x-values

Each table will be checked

table-1:

That we can see

-3, -2,-1 , 0, 1,2 x increase

And also -6,-3,-1,1,3,6 y increase 

It increases, thus,

table-2:

That we can see

-3, -2,-1 , 0, 1,2 x increase

But between -2 and 1, it's asking

The y-values of -4,-1,1,4..... are increasing

This increases, thus,

table-3:

Which we can see

-3, -2,-1 , 0, 1,2 x increase

But y changes between -3 and -5 .....this decreases

This does not increase, thus,

table-4:

we can find that the x increase to -3, -2, -1, 0, 1,2 however y rises from 7 to 1.....

This does not increase, thus,

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is [tex]\frac{8}{52}[/tex]

This can be simplified by dividing both the numerator and denominator by 4:

= [tex]\frac{2}{13}[/tex]

So, the probability is [tex]\frac{2}{13}[/tex]

-6 < x < -5

Step-by-step explanation:

(x+7)^5 = 20

Raise both sides to the (1/5) power

x + 7 = 1.820564203

Subtract 7 from both sides

x = -5.179435797

-6 < x < -5

[tex]5820[/tex] square inches

Step-by-step explanation:

For the rectangular prism in the middle:

[tex]24*30=720*2=1140[/tex]

[tex]10*30=300*2=600[/tex]

[tex]1140+600=1740[/tex]

For the left triangular prism:

[tex]10*24=240[/tex]

[tex]26*30=780[/tex]

[tex]24*30=720[/tex]

[tex]10*30=300[/tex]

[tex]240+780+720+300=2040[/tex]

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

[tex]1740+2040+2040=5820[/tex]
