A normal distribution has a mean of 15 and a standard deviation of 2. Find the value that corresponds to the 75th percentile. Ro

Sonbull [250]

Answer:

16.35

Step-by-step explanation:

Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.

First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.

Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get

$\frac{x-15}{2} = z\\\frac{x-15}{2} = 0.674\\x-15 = 0.674 * 2\\x = 0.674 * 2 + 15\\x= 16.348$

Rounding, we get x = 16.35 as our answer

Rectangle LOSP is shown below. The lengths, in units, of some of the line segments are also shown. Line segments MQ and NR are p

Galina-37 [17]

Answer: c. OSRN

Step-by-step explanation:

Sides of similar shapes are proportional.

For Rectangle LOSP,

Length = LO = 4+6+8 = 18 units

Width = OS= 12 units

Here, $\dfrac{18}{12}=\dfrac{3}{2}$ [proportionality constant]

a. For Rectangle LMQP,

Length = MQ = 12 units

Width = LM = 4 units

Here, $\dfrac{12}{4}=3\neq\dfrac32$

LMQP is not similar to LOSP.

b. Similarly, for LNRP,

Width = LN= 4+6 = 10

length = NR = 12

$\dfrac{12}{10}\neq\dfrac32$

LNRP is not similar to LOSP.

c. For OSRN,

Length = OS = 12

Width = ON = 8

$\dfrac{12}{8}=\dfrac32$

OSRN is similar to LOSP.

d. For MNRQ,

Length= NR = 12

Width = MN = 6

$\dfrac{12}{6}=2\neq\dfrac32$

MNRQ is not similar to LOSP.

Hence, the shape similar to rectangle LOSP is OSRN.

Write an equation to match the graph:

jekas [21]

Answer:

f(x)= -|x + 1| + 1

Step-by-step explanation:

This is an absolute value equation, because it's that v-shape that let's us know it will be one. The standard form is

f(x)= a|x - h| + k, where h is the horizontal shift, k is the vertical shift, and a is the dilation factor.

We know that the graph is moved up one, because its vertex is at y = 1. So k = 1.

f(x)= a|x - h| + 1

We also know that it must be negative, because it's upside-down, so <em>put the negative outside the absolute value, not inside.</em>

f(x)= -|x - h| + 1

Lastly, the horizontal shift is left one, so we know that h = -1.

f(x)= -|x - -1| + 1

x minus a negative one equals x plus one, so

<u>f(x)= -|x + 1| + 1 </u>is our final answer.
