(10^7)^2 as a single exponent

if ashley is in the 85th percentile and the mean of her test scores is 80 with a standard deviation of 15, which of the followin

kkurt [141]

The 85th percentile is a probability of 0.85 and its location is shown in the bell curve below

We need to look up on the z-table the value of z when P(Z<z) = 0.85 or P(Z>z) = 0.15

Value of z-score when p-value P(Z>z) = 0.15 is z = 1.0364

Next step is to use the formula of z-score to work out X
z-score = (X-μ) / σ
1.0364 = (X-80) / 15
1.0364 × 15 = X - 80
X = 15.546 + 80
X = 95.5

Most likely score that Ashley gets is 95.5

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Consider the graph of the function f(x)=I

Olin [163]

The matching of each transformed function is as follows;

g(x) = 2f(x) → y-intercept at (0,2)

h(x) = f(x) + 2 → asymptote of y=2

j(x) = f(x + 2) → y-intercept at (0,4)

m(x) = function decreases as x increases

<h3>How to match transformations?</h3>

A function is simply defined as a relationship between the inputs and the outputs. Now, we want to map each transformed function.

From the graph of this question as shown in the attached brainly link, the correct matching of each transformation of function f(x) = In x with a feature of the transformed function are as follows;

g(x) = 2f(x) → y-intercept at (0,2)

h(x) = f(x) + 2 → asymptote of y=2

j(x) = f(x + 2) → y-intercept at (0,4)

m(x) = function decreases as x increases

Last spring, the drama department at Manchester High School had 12 students audition for the musical. This spring, there were 15

tamaranim1 [39]

Answer:

25%

Step-by-step explanation:

The percent of increase can be calculated using following formula:

$\text{Percent Increase}=\dfrac{\text{Final Amount-Initial Amount}}{\text{Initial Amount}}\cdot 100\%.$

In your case,

Initial amount = 12 students;
Final amount = 15 students,

then

$\text{Percent Increase}=\dfrac{15-12}{12}\cdot 100\%=\dfrac{3}{12}\cdot 100\%=\dfrac{1}{4}\cdot 100\%=25\%.$
