Answer:

x = 23/5 OR 4.6

y = 157/15 OR 10.46

Step-by-step explanation:

x = 4x + 6x - 33 = 13

> 10x - 33 = 13

> 10x = 13 + 33

> 10x = 46

y = 4 (25/5) + 3y = -13

> 92/5 + 37 = -13

> 3y = -13 - 92/5

> 3y = - 157/5

Alenkinab [10]

Answer:

58.73%

Step-by-step explanation:

What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.

We have that z is equal to:

z = (x - m) / (sd)

x is the value to evaluate, m the mean, sd the standard deviation

So for 2400 we have:

z = (2400 - 2488) / (250)

z = -0.35

and this value represents 0.3632

for 89 we have:

z = (2900 - 2488) / (250)

z = 1.65

and this value represents 0.9505

we subtract:

0.9505 - 0.3632 = 0.5873

Therefore the probability would be 58.73%

Which statements accurately describe the function f(x) = 3(16) Superscript three-fourths x? Select three options.

zzz [600]

Answer:

The initial value is 3.

The range is y greater than 0.

The simplified base is 8.

Step-by-step explanation:

The given function is $f(x) = 3(16)^{\frac{3}{4}x }$ ......... (1)

Therefore, the initial value of the function at x = 0 is $f(0) = 3(16)^{0} = 3$

Now, the domain can be any real value, since for all real value of x, y exists.

But, for no value of x the function has value < 0.

Therefore, y greater than 0 is the range of the function f(x).

Now, simplifying the equation (1) we will have

$f(x) = 3(16)^{\frac{3}{4}x } = 3(16^{\frac{3}{4} } )^{x} = 3(8)^{x}$

Therefore, the simplified base is 8. (Answer)

Which functions have graphs that are steeper than the graph of f(x)=−3x^2?

netineya [11]

Answer:

g(x)=−4x^2 and m(x)=4x^2

Step-by-step explanation:

A horizontal stretch or shrink happens when you multiply the parent function (in this case f(x) = x²) by a number. If this number is between 0 and 1, the graph will be stretched horizontally. If this number is greater than 1, the graph will be shrunk horizontally. If the number is between -1 and 0, the graph will be stretched horizontally and flipped; if the number is less than -1, the graph will be shrunk horizontally and flipped.

The graphs that are horizontally shrunk are steeper than the others. This is m(x)=4x^2 and g(x) = -4x^2.
