2x+8=y if x=6 then what is the value of y?

Norma-Jean [14]

Answer:

Step-by-step explanation:

If x = 6 the problem should look like this:

2 (x) + 8 = y -> place the 6 where x is.

2 (6) + 8 = y -> remember () means to multiply.

2 times 6 , add 8 , equals y

12 + 8 =y -> 12 +8 equals 20

20 = y

I hope this helps!!

Can someone check this for me? Thanks.

Yes it's SAS
AD = CD (given)
BD = BD (common side )
but since it didn't say AC丄BD
it's no way to prove the angels r 90° :/

but as it already given AD= CD
so it's proven that it's an isosceles triangle
therefore
∠BAD = ∠BCD (base ∠s isos. ∆)

therefore it's SAS (side angel side)

Ed and Taylor work together on a group quiz that has 20 multiple-choice questions, each with four choices for the possible answe

MissTica

Answer:

a. p = 0.25

b. n = 10, p = 0.25.

c. n = 10, p = 0.25.

d. n = 20, p = 0.25.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

a. For any single question on the quiz, what is p = chance of a correct guess?

4 options, 1 of which is correct. So

$p = \frac{1}{4} = 0.25$

So p = 0.25.

b. Let X = number of correct guesses that Isabelle makes. What are the values of n and p for the binomial distribution that describes X?

Should be Ed here.

Ed guesses answers for the first 10 questions

This means that $n = 10$ .

p is the same, so n = 10, p = 0.25.

c. Let Y = number of correct guesses that Taylor makes. What are the values of n and p for the binomial distribution that describes Y?

10 question, so $n = 10$ , p is the same.

d. Consider X + Y = total correct guesses that Isabelle and Taylor make. What are the values of n and p for the binomial distribution that describes X + Y?

20 questions, so $n = 20$

10 for Ed, with 0.25 probability, 10 for Taylor, with 0.25 probability. So

$p = \frac{10}{20}*0.25 + \frac{10}{20}*0.25 = 0.125 + 0.125 = 0.25$

So n = 20, p = 0.25.

A cone and a cylinder have the same height and their bases are congruent circles

sveticcg [70]

Answer:

30 cm^3

Step-by-step explanation:

Given

radius for both shape = r

height for both shape = h

volume of cylinder is given by $\pi r^2h$

volume of cone is given by $1/3(\pi r^2h)$

From above two equation we can see that $\pi r^2h$ is volume of cylinder

thus we can say that volume of cone is 1/3(volume of cylinder)

So we can say that for any cylinder and cone whose height is same and base is congruent

volume of cone will be one-third of volume of cylinder.

Now in given problem

volume of cylinder is 90 cm^3

So , volume of given cone will be one-third of 90 cm^3

which is 1/3*90 cm^3 = 30 cm^3.

Thus, volume of the given cone is 30 cm^3.
