Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)

What's the pattern for 2,4,7,9

Semenov [28]

Answer:

The pattern is this: I create a function p(x) such that

p(1)=1

p(2)=1

p(3)=3

p(4)=4

p(5)=6

p(6)=7

p(7)=9

Therefore, trivially evaluating at x=8 gives:

p(8)= 420+(cos(15))^3 -(arccsc(0.304))^(e^56) + zeta(2)

Ok, I know this isn’t what you were looking for. Be careful, you must specify what type of pattern is needed, because the above satisfies the given constraints.

Express your final answer in simplest form 3/5 + -7/8

frez [133]

Answer:

- 0.5

Step-by-step explanation:

you first change the fractions numbers in to decimal form

so; 2/5 = 0.4

-7/8 = - 0.875

hence; 0.4 + (-0.875)

= - 0.475

in to its simplest form = - 0.5

the answer is - 0.5

Graph the following equations on the graphs below. <br> ( GRAPHING PAPER NEEDED, NOT A WEBSITE )

kodGreya [7K]

First, you want to identify the slopes and y-int.

Equation 1 = y = -2x + 2

Slope = -2

y-int. = 2 or (0,2)

Equationt 2 = y = 2x + 3

Slope = 2

Y-int. = 3 or (0,3)

To graph, first plot the y-intercepts. Then do the slopes.

Slope = -2

Down 2 over 1 (to the right)

Slope = 2

Up 2 over 1 (to the right)

Then just connect the dots in a line!

A set of city temperatures in April are normally distributed with a mean of 19.7 degrees Celsius and a standard deviation of 2 d

Sati [7]

Answer:

19.77% of average city temperatures are higher than that of Cairo

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 19.7, \sigma = 2$
