Which value of f makes 3f+5=32 a true statement? a. f=6 b. f=8 c. f=9 d. f=12

DIA [1.3K]

We just need to solve the equation in order to find the value.

$3f+5=32$

So we subtract 5 from both sides of the euqation and get

$3f=27$

Now we divide by 3 on both sides and get

$f=9$

So the answer is C.

Hope this helps!

Answer:

z = 4

y = -1

x = 2

Step-by-step explanation:

x - y = 3

Therefore => x = 3 + y

y + 2z =7

Therefore => y= 7 - 2z

We have the equation :

2x + 3y + 4z = 17

2(3 + y) + 3(7 - 2z) + 4z = 17

6 + 2y + 21 - 6z +4z = 17

2(7 -2z) - 2z + 27 = 17

14 - 4z - 2z + 27 = 17

-6z + 41 = 17

-6z = -24

z = 4

Answer:

The 95% confidence interval $81.852 < \mu < 280.098$

Step-by-step explanation:

From the question we are told that

The sample mean is $\= x = 180.975$

The standard deviation is $\sigma = 143.042$

The sample size is n = 8

Given that the confidence level is 95% then the level of significance is

$\alpha =( 100- 95) \%$

=> $\alpha =0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{ 143.042 }{\sqrt{8} }$

=> $E = 99.123$

Generally 95% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $180.975 -99.123 < p < 180.975 +99.123$

=> $81.852 < \mu < 280.098$
