Work out the value of x in the following. (See photo)
AfilCa [17]
A) 2^(x+3)= 4^(2x)
make base number the same
2^(x+3)= 2^2 (2x)
set the exponents equal to eachother
x+3=2 (2x)
x+3=4x
-x both sides
3=3x
÷3 both sides
x=1

b) 16^(1/5)×2^(x)=8^(3/4)
make base same number
2^4 (1/5)×2^(x)=2^3 (3/4)
2^(4/5)×2^(x)=2^(9/4)
set exponents
4/5 +x=9/4
-4/5 both sides
x= 29/20

Answer:

14 in²; D.

Step-by-step explanation:

Hey!

To find the area of a trapezoid, we will add up both of the bases, divide by two, and then multiply the height.

In that case, we'll start by adding up 5 and 9.

5 + 9 = 14

\frac{14}{2} = 7.

7 × 2 (height) = 14.

Thus, the area of the given trapezoid is \boxed{14\:in^2}, or D.

Hope this helps!

Rasek [7]

Answer:

\mu_{p} = p = 0.06

And the standard error is given by:

SE_{p} = \sqrt{\frac{\hat p(1-\hat p)}{n}}

And replacing we got:

SE_[p]= \sqrt{\frac{0.06*(1-0.06)}{373}}= 0.0123

And we want to find this probability:

P(\hat p < 0.03)

We can calculate the z score for this case and we got:

z = \frac{\hat p -\mu_p}{\Se_p} = \frac{0.03-0.06}{0.0123}= -2.440

And using the normal distribution table or excel we got:

P(\hat p < 0.03)= P(Z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

Solution to the problem

For this case we can find the mean and standard error for the sample proportion with these formulas:

\mu_{p} = p = 0.06

And the standard error is given by:

SE_{p} = \sqrt{\frac{\hat p(1-\hat p)}{n}}

And replacing we got:

SE_[p]= \sqrt{\frac{0.06*(1-0.06)}{373}}= 0.0123

And we want to find this probability:

P(\hat p < 0.03)

We can calculate the z score for this case and we got:

z = \frac{\hat p -\mu_p}{\SE_p} = \frac{0.03-0.06}{0.0123}= -2.440

And using the normal distribution table or excel we got:

P(\hat p < 0.03)= P(Z
