Divide. Write your answer in simplest form.
8/7÷4
Answer:
8/7 ÷ 4/1 = 7/32
Step-by-step explanation:
4/1 is the same as 4, flip all the Fractions so the bottom number is on the top and top on bottom and then multiply top x top and bottom x bottom
Hey there!
First, let's convert 4 into a fraction:
4=4/1
Now, divide the fractions:
[tex]\bold{\displaystyle\frac{8}{7} :\frac{4}{1}}[/tex]
Now, flop the second fraction over and multiply the first fraction times the second one:
[tex]\bold{\displaystyle\frac{8}{7} *\frac{1}{4}}[/tex]
Multiply the numerator (8) times the numerator of the second fraction (1) and multiply the denominator (7) times the denominator of the second fraction (4):
[tex]\bold{\displaystyle\frac{8}{28}}}[/tex]
Also, this fraction can be reduced:
[tex]\bold{\displaystyle\frac{4}{14}}[/tex]
We can divide by 2 again.
Hence, the answer is
[tex]\boxed{\boxed{\bold{\displaystyle\frac{2}{7}} }}}[/tex]
Hope everything is clear.

Dudley Durite deposited $350 into a savings account that earns 6.5% interest compounded semi annually. What amount was in his account at the end of 1 year?
Answer:
$373.12
Step-by-step explanation:
You want to set this up with the equation for compound interest which is [tex]A=P(1+\frac{r}{n})}^{nt}[/tex]. A stands for amount, P stands for principle which in this case is 350, r is rate which for this one is .065, ad n is the amount of times compounded per year, and since it is compounded semi annually you do 2 for 2 times a year. Your equation based on this information should look like this:
[tex]A=350(1+\frac{.065}{2})}^{(2)(1)}[/tex]
After working this out you get A = 373.12

find the value of x ?
Answer:
Step-by-step explanation:
∠E = ∠G
∠D= ∠F because it’s a parallelogram ==> D=F=2x+12 and E=G=5x
5x+2x+12=180
7x=168
X=24
Solution 2:
2*5x+2*(2x+12)=360
10x+4x+24=360
14x=360-24=336
X=336/14
X=24
Answer:

A/Q
5x+2x+12=180(Sum of adjacent angles is 180)

Complete Question
It is found that on average, 9% of the population recycles its garbage. Under this assumption, if a random sample of 120 households in Iowa City is taken, would you be surprised to find that fewer than 3% of households in the sample recycle their garbage? Use the fact that p-hat has an approximately normal distribution.
Group of answer choices
A I would not be surprised because there are lots of lazy students in Iowa City.
B I would not be surprised because 3% is not that far away from 9%.
C I would be surprised because Iowa City is a very clean community which means lots of people recycle their garbage.
D I would be surprised because if the 9% average is true, the chance of a sample proportion being less than 3% is very small (only 1%). Who cares? It's only garbage!
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is n = 120
The mean of the proportion is p = 0.09
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\frac{p(1-p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.09(1-0.09)}{120 } }[/tex]
=> [tex]\sigma = 0.02612[/tex]
Generally the chance that fewer than 3% of households in the sample recycle their garbage is mathematically represented as
[tex]P(X < 0.03) = P( \frac{X - p}{\sigma} < \frac{0.03 -0.09}{0.02612} )[/tex]
[tex]P(X < 0.03) = P( Z < -2.297 )[/tex]
From the z-table
[tex]P( Z < -2.297 ) = 0.01[/tex]
=> [tex]P(X < 0.03) = 0.01/tex]
=> [tex]P(X < 0.03) = 1\% /tex]

Which graph represents the function?
f(x)={3 if x<1x if x≥1
Answer:
Top Right
Step-by-step explanation:
If it's x≥1, you would plot a closed (or filled) circle at 1, and it would continue going right. If it's x<1, you would plot an open (or an o) circle with a line continuing left.
The function represents f(x)={3 if x<1x if x≥1 in Figure 4 is correct.
What is slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. There is no clear reason why the letter m is employed for slope, however its earliest use in English can be found in O'Brien (1844), who wrote the equation of the a straight line as "y = mx + b," and it can also found in Todhunter (1888), who wrote it as "y = mx + c." Slope is frequently denoted by the letter x. The ratio of the "vertical change" to the "horizontal change" between (any) two distinct points along a line is used to calculate slope. The ratio can also be written as a quotient ("rise over run"), which produces the same number for each and every two distinct points on a single line.
Here,
For x≥1 ⇒ f(x)=x
For x<1 ⇒ f(x)=3
Both these statements are followed together only in figure 4.
Hence, figure 4 is correct.

a train moves at a speed of 60 km per hour.how far will it travel in 30 minutes
Answer:
The train would travel 30km in 30 minutes.
Step-by-step explanation:
Speed of train = 60km/hr
30 minutes = I hour ÷ 2
If 30 minutes is equal to half an hour, and it takes an hour for the train to travel 60 km, then you would have to half 60 km to find the length travelled in 30 minutes.
Equation: 60km ÷ 2 = 30km

Answer:
Its divide and 4
Step-by-step explanation:
To find the values in each row divide the values in previous row by 4.
What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Clearly, from observation,
Each column represent geometric progression with common ratio r = 1/4. So when moving downward, the element in the rows decreases as multiple of 1/4.
Here,
R(1, 1) = 256
R (2 ,1) = 64
R(2,1)/R(1,1)=1/4
Thus, To find the values in each row divide the values in previous row by 4.

Which of the following r-values represents the strongest correlation?
Which of the following r-values represents the strongest correlation?
A. -0.51 B.-0.71 C. -0.41 D. -0.61
Answer:
-0.71
Step-by-step explanation:
Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation.
The r-value that represents the strongest correlation is -0.71.
What is correlation?Any of the many metrics used to describe the strength and direction of a linear relationship between two random variables is called a correlation coefficient.
So, r stands for the correlation coefficient.
Depending on the direction of the association, an r-value may be either negative or positive.
Yet, the link is greater the closer an r-value is to 1.
Here - 0.71 is closer to -1 then it is having a strongest correlation.
