Which expression is equivalent to 8+18a−2+6a? A.24a+6 B.24a + 10 C.8(1+2a)−(2+6a) D.30a

lakkis [162]

Hey there!

$8 + 18a - 2 + 6a$

Combine Like terms: $18a, 6a, \\ \\ 8,2$

So, $(18a + 6a) = 24a \\ \\ 8+ (-2) = 6$

$Answer: 24a + 6$ would be $equivalent$ to: $8 + 18a - 2 + 6a$

Good luck on your assignment and enjoy your day!

Which properties are present in a table that represents an exponential function in the form y=b^x when b > 1? I. As the x-val

Scilla [17]

Answer:

Properties that are present are

Property I

Property IV

Step-by-step explanation:

The function given to us is where b > 1

Let us take a function, for example,

Now, let us check the conditions before we continue:

I. When the x-values increases, the y-values will also increase.

Let us put some values:

y = 2 ^ 1

which results to y = 2

and

y = 2 ^ 2

which results to y = 4

So this is definetly TRUE.

II. The point: (1,0) is in the table.

Ok, now let us put 1 into x and try to see if it gives us 0

y = 2 ^ 1

y = 2

So this is surely FALSE.

III. As the x-value increase, the y-value decrease.

We have already seen that as x increase, y also increase in part I.

So this is FALSE.

IV. as the x value actually decrease. Now, the y values decrease approaching a singular value.

The exponential function of this form will NEVER go to 0 and is NEVER negative. So as x decreases, y also decrease and came to a value (that is 0) but never becomes 0.

This is TRUE.

Therefore, Option I and Option IV are true.

Help please! Figure JKLM is a parallelogram. The measures of line segments MT and TK are shown. What is the value of MT? A.) 7 B

Zinaida [17]

Hey there! :)

Answer:

C) 74 units.

Step-by-step explanation:

MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:

8y + 18 = 12y - 10

Subtract 8y from both sides:

18 = 4y - 10

Add 10 to both sides:

28 = 4y

Divide both sides by 4:

28/4 = 4y/4

y = 7 units. Plug this into the equation for MT:

8(7) + 18 = 74 units.

37% of women consider themselves fans of professional baseball. you randomly select six women and ask each if she considers hers

valina [46]

Answer:

(a) 2.22

(b) 1.3986

Step-by-step explanation:

Let X denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, p = 0.37.

A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

$\text{Mean}=np=6\times 0.37=2.22$

(b)

Compute the variance of the binomial distribution as follows:

$\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986$

(c)

Compute the standard deviation of the binomial distribution as follows:

$\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183$
