∑ Hey, petalssquad10 ⊃

Answer:

( 10 x + 10 ) = 110

Step-by-step explanation:

As you can see this following diagram shown a vertical angles which  are angles that are opposite of each other when two lines cross. You can also see it kind of look like a "x". Vertical angles also means that they have the same angle measure. A example is if this angle is "110" then the other sides equal to "110''.

Hence, the equation we can be used to solve for x in the following diagram is:

( 10 x + 10 ) = 110

You can also refer to the image below:

So, here we have an exponential function.

Remember that an exponential function has the form:

y=a(b)^x=a(1\pm\frac{r}{100})^x

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).

So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

\begin{gathered} a=40 \\ b=1+\frac{13}{100}=1.13 \end{gathered}

So,

f(x)=40(1.13)^x

For city B:

\begin{gathered} a=40 \\ b=1+\frac{16}{100}=1.16 \\ g(x)=40(1.16)^x \end{gathered}

But something different happens with city C. This is not an exponential function, this is a linear function.

So,

h(x)=40+10x

Help me as fast as you can make sure you show me how to work it out just type the answer
oksian1 [2.3K]

Answer:

to find compound interest

it is

p(1+r) ^n

p stands for principa

r is the rate (percentage)

n is the amount of years

820(1+3.5 ) ^ 5

100

chsnge the percentsge to a decimal and add it to 1.

820(1 + 0.035) ^ 5

820(1.035)^5

raise what is in the bracket to the power of 5 which is the amount of years

820× 1.19

=£975.80

im not good with simple interest,could someone else show her how to do it please

Assume the random variable X is normally distributed with mean μ = 50 and standard deviation σ= 7. Compute the probability.
Irina18 [472]

Complete question is;

Assume the random variable X is normally distributed with mean μ = 50 and standard deviation σ = 7. What is the probability P (X > 42)?

Answer:

P(X > 42) = 0.1271

Step-by-step explanation:

We are given;

mean; μ = 50

Standard deviation; σ = 7

Formula for the z-score is;

z = (x - μ)/σ

Thus;

z = (42 - 50)/7

z = -1.14

Since we are looking for P (X > 42), then let's look up this z-value from the z-distribution table attached.

We have;

P(X > 42) = 0.1271

Solve the proportion below. 7/x = 19/144
timofeeve [1]

Answer:

\boxed{\boxed{\tt B)\: 42}}

<h3>Step-by-step explanation:</h3>

\tt \cfrac{7}{x}=\cfrac{19}{114}

<u>Cross multiply:</u>

(Multiply the numerator in the first fraction times the denominator in the second fraction, then multiply the numerator of the second fraction times the number in the denominator of your first fraction.)

\longmapsto\tt 798=x\times \:19

<u>Switch sides:</u>

\longmapsto\tt x\times \:19=798

<u>Divide both sides by 19:</u>

\longmapsto\tt \cfrac{x\times \:19}{19}=\cfrac{798}{19}

<u>Divide 798 by 19 = 42</u>

\longmapsto\tt x=\cfrac{798}{19}

\hookrightarrow \tt x=42
