Answer: 6

Explanation:
Functions are relations where there is only one y-value for each x-value.

If the chart represents a function, each number can only be used once in the “x” row.

Since -2, 5 and 8 were already used, the missing value is 6.

Which value of x from the set {5, 6, 7, 8} makes this equation true? 3x = 24

Tju [1.3M]

Answer:

Value x = 8 make the equation true .

Step-by-step explanation:

Given : 3x = 24.

To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?

Solution : We have given 3x = 24.

The equations are true when the Left hand side and right hand side of the equation are equal.

Then,

For x = 8 .

3 ( 8) = 24

24 = 24 .

Hence,

Left hand side = Right hand side.

Therefore, Value x = 8 make the equation true .

Which equation is the inverse of y = 7x2 – 10?

MrRissso [65]

we have

$y=7x^{2}-10$

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

$x=7y^{2}-10$

Step 2

Isolate the variable y

$x=7y^{2}-10$

$7y^{2}=x+10$

$y^{2}= \frac{x+10}{7}$

Square Root both sides

$y=(+/-)\sqrt{\frac{x+10}{7}}$

Step 3

Let

$f(x)^{-1}=y$

so

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

therefore

<u>the answer is</u>

The inverse is

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

Grumpy Corp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines

Vedmedyk [2.9K]

Answer:

Hence, the probability of a Negative test is $P(T^C)=0.5904$ .

Step-by-step explanation:

(a)

Let $D=$ Drug user and $T=$ Test positive

Probability of drug users $P(D)=36\%=0.36$

$P(\frac{T}{D})=96\%=0.96$

$P(\frac{T^c}{D^c})=90\%=0.90$

(b)

Find the Probability of a Negative test,

$P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)$

$\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36$

$\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36$

$\Rightarrow P(T^C)=0.576+0.0144$

$\Rightarrow P(T^C)=0.5904$
