Answer:

There is a horizontal translation 4 units left, and and vertical translation 1 unit down.

Step-by-step explanation:

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Parent function: f(x) = (5)^x

Horizontal translation: 4 units left

Vertical translation: 1 unit down

Reflection about the x-axis: none

Vertical stretch: stretched

In a study, 42% of adults questions reported that their health was excellent. A researcher wishes to study the health of people

Vikki [24]

Answer: 0.0594

Step-by-step explanation:

Given : The population proportion of adults questions reported that their health was excellent : p = 0.42

Among the 14 adults randomly selected from this area, only 3 reported that their health was excellent.

i.e. Sample size : n= 14

$\mu=np = 14\times0.42=5.88$

$s=\sqrt{np(1-p)}=\sqrt{14(0.42)(1-0.42)}\approx1.85$

z-score : $z=\dfrac{{x}-\mu}{\sigma}$

Put x= 3

$z=\dfrac{3-5.88}{1.85}\approx-1.56$

Then, the probability that only 3 or fewer report having excellent health:-

$P(z\leq-1.56)=0.0593799\approx0.0594$

Hence, the required probability : 0.0594

the museum wants to display all the art pieces in rows. Each row has the same number of pieces and the same type of pieces. How

Alecsey [184]

So if you have 30 oil, 24 photos, 21 sketches, the first thing I notice is that all of these numbers are divisible by 3. Since there are no specifications of how many rows for each category. You can divde the 30/10, 24/8, and 21/7 you would have 10 rows oil, 8 rows of photos, and 7 rows of sketches. In short, I believe your answer should be 3.

Hope this helps! Sorry if this explanation is unclear, please feel free to ask questions. <3
