Answer:
We get the value of x: x= 2
Step-by-step explanation:
Since the triangles are similar, the ratios of the lengths of corresponding sides are same.
We can use proportions to find the value of x
The proportion will be:
[tex]\frac{BD}{DA}=\frac{BE}{EC}[/tex]
Now putting there values we can find value of x
We have:
BD = 6, DA = 4, BE = x+1, EC =x
Putting values
[tex]\frac{BD}{DA}=\frac{BE}{EC}\\\frac{6}{4}=\frac{x+1}{x} \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, we get the value of x: x= 2

c)[tex] \frac{x + 2}{x - 3} . \frac{4}{x + 2} [/tex]The graph shows the amount of profit in thousands of dollars for a toy each year .A scatter plot of the data is shown below with the line of best fit .
What statement are true related to the line of best fit ? Select all that apply
A.the amount of profit after the first year was around $0.
B.the amount of profit increases about $10,000 each year.
C.the amount of profit decreases about $10,000 each year.
D.the amount of profit after the first year was around $30,000.
E. The amount of profit after 10 years is approximately $120,000.
Answer:
Step-by-step explanation:
We want to confirm which of the given statement is true about the graph.
A) the amount of profit after the first year was around $0
-----------false
From the given graph, the amount of profit after year was far more $0. So the statement above is false.
B) The amount of profit increases about $10,000 each year ------------true
From the line of best fit shown in the graph, the amount of profit increases each year by approximately $10,000.
C) the amount of profit decrease about $10,000 each year ------------ False
From the line of best fit on the graph, we can observe that the amount of profit does not decrease. It rather increases every year.
D) the amount of profit after the first year was around $30,000 ------------true
From the given graph, the amount of profit after the first year is approximately $30,000.
So, the statement is true.
E) the amount of profit after 10 years is approximately $120,000 --------- true
At the year 10 on the graph , the corresponding amount of profit is $120,000.

Answer:

Step-by-step explanation:
The chart below describes the commissions earned by four different sales people. Sales Person Commission Earned Time on Sales Floor Alex $220 10 Hours Beth $40 120 minutes Cleo $120 300 minutes David $180 360 minutes Which sales person earned the most money per hour? A Alex B Beth C Cleo D David
Answer:
ALEX
Step-by-step explanation:
Because if u look it says ten minutes an e has 220 so that equals to almost 3'500 dollars Im only in 7th grade good luck
Answer:
Step-by-step explanation:
Heya, the correct answer is David. The tricky part is the Hours and minutes difference. by dividing 360 by 6 we'll get 60. That equals an hour. Which is what the original answerer got wrong. So, If we divide 180 by 6 we get 30. So actually, there is an 8-number difference between Alex's and David's answers. With David being right. 22-30

A department store's survey suggests that 76% of shoppers buy food, 49% buy clothes, and 28% buy both food and
clothes Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the
probability that the shopper also buys food?
027
0.39
0.57
0.64
Answer:
0.57
Step-by-step explanation:
Given that:
food = f ; c = clothes
P(f) = 0.76
P(C) = 0.49
P(fnC) = 0.28
Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?
P(f Given C) = P(f | C)
P(f | c) = p(fnC) / p(C)
P(f | c) = 0.28 / 0.49
P(f | c) = 0.5714
P(f | c) = 0.57
Answer:
.57

Find the percentage of change round to the nearest cent whole percent if necessary state whether the percent of change is an increase or decrease
3 months to 5 months
5 to 10
$0.32 to $.37
Answer with explanation:
Percentage change = [tex]\dfrac{Change}{Previous\ value}\times100[/tex]
a) 3 months to 5 months
Change = 5 - 3 ( increase )
Percentage change = [tex]\dfrac{2}{3}\times100\%=66.67\%[/tex] , it is an increase .
b) 5 to 10
Change = 10-5 = 5 ( increase)
Percentage change = [tex]\dfrac{5}{5}\times100\%= 100\%[/tex], it is an increase .
c) $0.32 to $.37
Change = 0.37-0.32 = 0.05 ( increase)
Percentage change = [tex]\dfrac{0.05}{0.37}\times100\%=13.51\%[/tex], it is an increase .

Suppose we want to test to see if a roulette wheel is balanced. The wheel is spun 100 time resulting in 58 red outcomes. Is this evidence that the roulette wheel is out of balance
Solution :
Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes
[tex]$ \hat p =\frac{58}{100}$[/tex]
[tex]$ \hat p$[/tex] = 0.58
So we have to test,
[tex]$H_0 : p = 0.5$[/tex]
V/S [tex]$H_a: p \neq 0.5 $[/tex]
The test statistic is
[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]
[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]
[tex]$=\frac{0.08}{0.05}$[/tex]
= 1.600
P value using the z table is 0.110
So P value greater than 0.05
Therefore, there is no evidence that roulette wheel is out of balance.

Answer:
10 Gallons of water will weigh 1.2 pounds.
Step-by-step explanation:
Each gallon weighs 0.12 pounds, I got this answer from dividing 3 by 25 to see how much one gallon weighs. So if we multiply the weight of one gallon by 10, 0.12*10, then we will find out the weight of ten gallons.
I hope this helped you!! You can ask questions any question you may have, if needed, and I will answer them :)
10 Gallons of water will weigh 1.2 pounds.
Here, we have,
given that,
Morgan know that 3 gallons of water weigh 25 pounds.
now, we need to find how much do 10 gallons weigh.
so, we get,
3 gallons of water weigh 25 pounds.
so, to see how much one gallon weighs we divide 3 by 25 .
i.e. 3/25 = 0.12
Each gallon weighs 0.12 pounds,
So if we multiply the weight of one gallon by 10,
i.e. 0.12*10, then we will find out the weight of ten gallons.
so, we get,
10 gallons weigh = 0.12*10 = 1.2 pounds.

Which value is in the domain of f(x)?
Answer: x = 4
Step-by-step explanation:
Here we have a piecewise function.
One piece works for values of x such that: -6 < x < 0
And the other piece works for values of x such that: 0 < x ≤ 4
Then the domain of this function is:
D = (-6, 0) U (0, 4]
Notice that, becuse we use the symbols ><, the values of x:
x = -6
x = 0
Do not belong to this domain.
While becuase we use the symbol ≤ in the right end, the value x = 4 does belong to the domain.
Then for the given options, the only value that belongs to the domain is the third option, x = 4.
