Question 1
-1 / 2 = y - 1
-1 / 2 + 1 = y
y = 1 / 2

Question 2
-3π + w = 2π
w = 2π + 3π
w = 5π

Question 3
1.2m = 0.6
m = 0.6 / 1.2
m = -0.2

Question 4
q + 2.7 + -0.9
q + 2.7 = 0.9
q = 0.9 - 2.7
q = -1.8

$-\frac{1}{2} = y -1\\y=0.5$

$-3\pi + w = 2\pi\\w= 5\pi$

$1.2m = 0.6\\m = 0.5$

 $q + 2.7 + (-0.9) = q + 1.8$

What is the true solution to the equation below? ln e^lnx^2=2 ln 8?

arlik [135]

$x\ \textgreater \ 0\\\\
\ln e^{\ln x}+\ln e^{\ln x^2}=2\ln 8\\
\ln x+\ln x^2=\ln 8^2\\
\ln (x\cdot x^2)=\ln 64\\
\ln x^3=\ln 64\\
x^3=64\\
x=4\Rightarrow \text {B}

I NEED HELP WITH THIS Q1

levacccp [35]

Answer:

$\frac{1}{4} (x-5)=13$

Step-by-step explanation:

So when we multiply this is what we get:

$\frac{x-5}{4}=13$

then we multiply the 4 by 13:

$x-5=52$

then after that we add 52+5 and we get:

$x=57\\$

A bar graph is when you want to compare the data in the data set (which this data set does)

A line graph is used when the data set creates a straight line (which this data set does not)

A circle graph (also known as a pie chart) is used when the data set measures percentages that will total 100% (which this data set does not)

A stem plot is used when you want to show the frequency of the beginning digit or digits (which this data set does not)

. Which algebraic expression is equivalent to the expression below?

I am Lyosha [343]

Since you are not distributing at all, you can ignore the parenthesis :)

When ignoring the parenthesis your equation is
18x + 11 - 4x

Then just combine like terms :)

14x + 11

Your answer is C.

Hope this helped!

32% of college students say they use credit cards because of the rewards program. You randomly select 10 college students and a

Tems11 [23]

Answer:

a) $P(X=2)=(10C2)(0.32)^2 (1-0.32)^{10-2}=0.211$

b) $P(X> 2)=1-P(X\leq 2)=1-[0.0211+0.0995+0.211]=0.668$

c) $P(2 \leq x \leq 5)=0.211+0.264+0.218+0.123=0.816$

Step-by-step explanation:

1) Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

2) Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=10, p=0.32)$
