vladimir2022 [97]

Answer:

d. y = -2×

Step-by-step explanation:

First to solve find the slope using the formula, \frac{10+10}{-5-5}. The slope equals 20/-10 or -2. Then plug the slope and point, (-5,10), into slope-point form. y-10=-2(x+5), then solve for y. This gives you y=-2x+0 or y=-2x.

If 3x-y=123x−y=123, x, minus, y, equals, 12, what is the value of \dfrac{8^x}{2^y} 2 y 8 x ​ start fraction, 8, start superscrip
julia-pushkina [17]

Answer:

2^{12}=4,096

Step-by-step explanation:

You know that 3x-y=12 and have to find

\dfrac{8^x}{2^y}

Use the main properties of exponents:

1. (a^m)^n=a^{m\cdot n}

2. \dfrac{a^m}{a^n}=a^{m-n}

Note that

8=2^3,

then

7^x=(2^3)^x=2^{3\cdot x}=2^{3x}

Now

\dfrac{8^x}{2^y}=\dfrac{2^{3x}}{2^y}=2^{3x-y}

Since 3x-y=12, then 2^{3x-y}=2^{12}=4,096

Mice21 [21]

Answer:

The Mean is not equal to $31,129.

Step-by-step explanation:

Consider the provided information.

The mean is $31129

Thus, the null hypothesis H_0: \mu = 31129

Alternative hypothesis H_a: \mu \neq 31129

A random sample of 15 firstyear CMAs in Denver produces a mean salary of $32,279, with a standard deviation of $1,797.

Thus the value mean of sample is 32279, standard deviation is 1797 and number of samples are 15.

Now use the 2 sided t-test.

t=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

Now substitute the respective values in the above formula.

t=\frac{32279-31129}{\frac{1797}{\sqrt{15}}}

t=\frac{1150}{464}

Test Value = 2.4785  approximately

Now, find the corresponding p-value in your t-table with DF(degree of freedom) 14.

p = 0.0265  

as the value of  p < 0.05, so you reject null hypothesis.  

Thus, the Mean is not equal to $31,129.
