Answer:

$1.0378*10^{-2}$

Step-by-step explanation:

we know that

To multiply numbers in scientific notation, first multiply the coefficients and then add the exponents

we have

$(1.18*10^3)(9.1*10^{-6})=(1.18*9.1)*10^{(3-6)}=10.738*10^{-3} =1.0378*10^{-2}$

PQ has endpoints P(-4, -2) and Q(-6, 8). What is the length of segment PQ in simplest radical form?

harina [27]

Answer:

The answer is

<h2> $2 \sqrt{26} \: \: \: \: units$ </h2>

Step-by-step explanation:

The distance between two points of a line segment can be found by using the formula

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

P(-4, -2) and Q(-6, 8)

The length of the line segment is

$|PQ| = \sqrt{ ({ - 4 + 6})^{2} + ({ - 2 - 8})^{2} } \\ = \sqrt{ {2}^{2} + ({ - 10})^{2} } \\ = \sqrt{4 + 100} \\ = \sqrt{104} \: \: \: \: \: \: \: \\ = 2 \sqrt{26} \: \: \: \: \: \: \:$

We have the final answer as

$2 \sqrt{26} \: \: \: \: units$

Hope this helps you

PERSON WHO GETS IT RIGHT GETS BRAINLIEST

saul85 [17]

Step-by-step explanation:

Let x = number of games that Alex played

The total money that he spent C is given by

$C = 2x + 15$

If he spent $45, then we can write

$45 = 2x + 15$

Solving for x, we get

$2x = 45 - 15 = 30 \Rightarrow x = 15$

This means that Alex played 15 games.

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distribute

bulgar [2K]

Answer:

The area of the shaded region is 0.2898.

Step-by-step explanation:

Let <em>X</em> represent the IQ scores of adults.

It is provided that $X\sim N(100,15^{2})$ .

Compute the probability of an adult having an IQ between 106 and 124 as follows:

$P(106$

$=P(0.40$

*Use a <em>z</em>-table.

Thus, the area of the shaded region is 0.2898.
