Answer:

I believe the answer would be 1/8 of 64

Step-by-step explanation:

I think it means what fraction of 64 is 8, so in that case, 8 would be 1/8 of 64.

Assuming u mean what fraction of 64 is 8 the answer will indeed be 1/8, or 12.5%

This is correct because 8/8 equals 1 whole and 8x8 is 64

Which is the graph of f(x) = (x – 1)(x + 4)?

Arada [10]

Answer:

The fourth graph (last graph)

Step-by-step explanation:

Remember that the zeros of a function are the x-intercepts of the graph. To find the zeros we just need to set the function equal to zero and solve for x:

$f(x)=(x-1)(x+4)$

$(x-1)(x+4)=0$

$x-1=0,x+4=0$

$x=1,x=-4$

Now we know that the graph or our function intersects the x-axis at x = 1 and x = -4.

Since both x values inside the parenthesis are positive, our parabola is opening upwards.

The only graph opening upwards whose x-intercepts are x = 1 and x = -4 is the fourth one.

We can conclude that the graph of $f(x)=(x-1)(x+4)$ is the fourth one.

Question 27 of 28<br> 1 Point<br> What is the slope of the line shown below?<br> (3,-2)<br> (2,-4)

Gwar [14]

Answer:

The slope is 2

Step-by-step explanation:

To find the slope given two points, we use the formula

m = (y2-y1)/(x2-x1)

= (-4--2)/(2-3)

= (-4+2)/(2-3)

= -2/-1

= 2

A certain slot machine has three identical independent wheels, each with 13 symbols as follows: 1 bar, 2 lemons, 2 bells, 2 plum

kari74 [83]

Answer:

Step-by-step explanation:

Given

there are 13 symbols in slot machines i.e. 1 bar , 2 lemons , 2 bells ,2 plums ,3 cherries , 3 oranges

there are Total of 3 machines

Probability of getting bar in machine is $\frac{1}{13}$

Probability of getting 3 bar on 3 machine $=\frac{1}{13} \times\frac{1}{13}\times \frac{1}{13}=\frac{1}{2197}=0.0004$

Probability of getting an orange $=\frac{3}{13}$

Probability of getting 3 oranges on 3 machine $=\frac{3}{13} \times\frac{3}{13}\times \frac{3}{13}=\frac{27}{2197}=0.0122$

Probability of getting a Plum $=\frac{2}{13}$

Probability of getting 3 Plums on 3 machine $=\frac{2}{13} \times\frac{2}{13}\times \frac{2}{13}=\frac{8}{2197}=0.0036$

What is the coefficient of x2y3 in the expansion of (2x + y)5?

Zigmanuir [339]

Option C:

The coefficient of $x^{2} y^{3}$ is 40.

Solution:

Given expression:

$(2 x+y)^{5}$

Using binomial theorem:

$(a+b)^{n}=\sum_{i=0}^{n}\left(\begin{array}{l}n \\i\end{array}\right) a^{(n-i)} b^{i}$

Here $a=2 x, b=y$

Substitute in the binomial formula, we get

$(2x+y)^5=\sum_{i=0}^{5}\left(\begin{array}{l}5 \\i\end{array}\right)(2 x)^{(5-i)} y^{i}$

Now to expand the summation, substitute i = 0, 1, 2, 3, 4 and 5.

$$=\frac{5 !}{0 !(5-0) !}(2 x)^{5} y^{0}+\frac{5 !}{1 !(5-1) !}(2 x)^{4} y^{1}+\frac{5 !}{2 !(5-2) !}(2 x)^{3} y^{2}+\frac{5 !}{3 !(5-3) !}(2 x)^{2} y^{3}$
