What is 7/8 divided by 1/4
Answers
Answer:
7/2
Step-by-step explanation:
you got two fractions you wanna divide flip the right and multiply
7/8 times 4/1 = 7/2
7/8 divided by 1/4 is equal to 7/2.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. In this case, we have:
(7/8) ÷ (1/4)
To find the reciprocal of 1/4, we flip the fraction, which gives us 4/1.
Now, we can multiply the first fraction by the reciprocal:
(7/8) × (4/1)
Multiplying the numerators and denominators, we get:
(7 × 4) / (8 × 1)
28/8
The fraction 28/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(28 ÷ 4) / (8 ÷ 4)
7/2
Therefore, 7/8 divided by 1/4 is equal to 7/2.

HELPP!!! 30 POINTS!!! WILL MARK BRAINLYIST!! Step 1: Written Response (30 points) Using complete sentences, compare the fat content of the three restaurants above. Make sure to talk about skewedness, measures of center, and measures of spread. Also, make a recommendation for which restaurant you think is the "healthiest". Make sure to defend your recommendation using mathematical terms that you've learned in this unit.
Answers
Answer:
median a= 65 b= 75 c=68
This shows the median of each fat content of each restaurant showing that restaurant c is closer to that of 'restaurant a ' than a is to 'restaurant b' and near to 1/7 lower than that of restaurant b which shows they are all highly skewed with each other upon their graph.
The measures of spread start with 55 to 72 for 'restaurant a' where the upper and lower quartiles are 70-60 showing a distribution 10-17 into the whisker plot.
Compared to restaurant b which shows a measure of spread start with 65 to 90 for 'restaurant b' where the upper and lower quartiles are 85 - 68 into the whisker plot and show a spread of 3 in the left exterior and 5 spread in the right exterior to the upper quartile. So in comparison to restaurant a that restaurant b has a greater spread in the interquartile range = 15 where restaurant a =10.
For the outer quartile the comparison to restaurant a is twice as small meaning restaurant a is greater by over double and shown as 53 <a < 60 which when showing both outer quartiles we can use the amounts being 7 and 70<a<72 = 2
and show closed dots on equality line number line separately showing a<-7 and a>2 for each outer exterior quartile. For restaurant b this shows opposite similar equalities 65<b< 68 = b>-3 and 82<b<89 = b>7
So the differences are smaller for b for left side by 4 and larger for b by 5 up on the right side.
We compare both to restaurant c and find c = 60<c<61 = c>-1 and 70<c<71 = c>1 so the differences are that the outer quartile for c through the other quartiles = -2> c < -6 . This shows how smaller c is compared to a and b outer quartiles). We can also prove that while the outer quartiles are much more smaller for c than a and b we cna prove that c actually has an inner quartile more similar to c and closer distribution of b as the median is more closer for a and c where b has a greater output for median as restaurant b has the higher fat content and greater distribution within the inner quartiles over all.
Summary findings Restaurant c outer quartile is moderately skewed as they show -1 -0.5 on the left side and 1-0.5 on the right side. Restaurant a has a closer median inner quartile to c and closer distribution of inner distribution of c. It's output outer quartile distribiution is a distribution that is higher than b but a smaller inner quartile compared to b, when this happens then the distribution spread shows less range and fewer products to account for.
So i think restaurant b has the higher fat content to its menu.
Where restaurant a must be the healthiest as it holds the lowest range and larger gap is such range for healthier food.ie) when compared to the others.
Meanings of what we are asked.
In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range. the median is marked by a vertical line inside the box. the whiskers are the two lines outside the box that extend to the highest and lowest observations.
Skewness refers to distortion or asymmetry in a symmetrical bell curve, or normal distribution, in a set of data. If the curve is shifted to the left or to the right, it is said to be skewed. Skewness can be quantified as a representation of the extent to which a given distribution varies from a normal distribution.
As a general rule of thumb:
If skewness is less than -1 or greater than 1, the distribution is highly skewed.
If skewness is between -1 and -0.5 or between 0.5 and 1, the distribution is moderately skewed.
If skewness is between -0.5 and 0.5, the distribution is approximately symmetric.

[tex]a^{3y} + 1 = (a^{y}+1 )^{3} - 3a^y(a^{y}+1)\\\\[/tex]
Step-by-step explanation:
We are to factorize the expression [tex]a^{3y} + 1[/tex] completely. To do this, we will apply the expression below;
The expression can be rewritten as [tex]a^{3y} + 1^{3}[/tex]
To factorize the expression, we need to first factorize [tex](a^{y}+1 )^{3}[/tex] first
[tex](a^{y}+1 )^{3} =(a^{y}+1 )(a^{y}+1 )^{2}\\= (a^{y}+1 )((a^y)^{2} } + 2a^{y} +1)\\= (a^y)^{3} +2(a^y)^{2}+a^y+( a^y)^{2}+2a^y+1\\(a^{y}+1 )^{3} = ((a^y)^{3} + 1) +2(a^y)^{2}+a^y+( a^y)^{2}+2a^y\\(a^{y}+1 )^{3} = ((a^y)^{3} + 1) +3(a^y)^{2}+3a^y\\[/tex]
The we will make [tex]a^{3y} + 1^{3}[/tex] the subject of the formula as shown;
[tex](a^y)^{3} + 1 = (a^{y}+1 )^{3} - (3(a^y)^{2}+3a^y)\\(a^y)^{3} + 1^{3} = (a^{y}+1 )^{3} - (3(a^y)^{2}+3a^y)\\\\[/tex]
[tex](a^y)^{3} + 1 = (a^{y}+1 )^{3} - (3(a^y)^{2}+3a^y)\\\\[/tex]
[tex]a^{3y} + 1 = (a^{y}+1 )^{3} - (3(a^y)^{2}+3a^y)\\\\[/tex]
[tex]a^{3y} + 1 = (a^{y}+1 )^{3} - 3a^y(a^{y}+1)\\\\[/tex]

Answers
Answer:

Step-by-step explanation:
-2(8x - 4) < 2x + 5
Distribute
-16x +8 < 2x+5
Add 16x to each side
-16x+16x +8 < 2x+16x+5
8 < 18x +5
Subtract 5 from each side
8-5 <18x
3 <18x
Divide by 18
3/18 <x
1/6 <x
-2(8x - 4) < 2x + 5
Expand the brackets.
-16x +8 < 2x + 5
Add -2x and -8 on both sides.
-16x -2x<5-8
-18x<-3
Multiply both sides with -1 (reverse the inequalty).
18x>3
Divide 18 into both sides.

Sarah will earn $ 21.60 following the percentage increase
What Does Percent Mean?A ratio or figure stated as a fraction of 100 is called a percentage. The percent marker is frequently used to indicate it,%
The approximation error in a data value is the distinction between a precise value and one that is close to it. This error may be referred to as either an absolute error or a relative error.
The difference between the measured value and the true value, expressed as a percentage of the true value, is known as a percentage change.
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Let the amount Sarah will get following the percentage increase be A given the available facts.
Right now, Sarah's starting salary is $ 18.00.
20% is the proportion that hourly work will rise.
Hence, the amount of increased hourly work equals 20% of Sarah's starting salary.
Simplifying results in
The increase in hourly pay is (20/100) times 18 ($3.60)
Now, the amount Sarah will get following the % increase is A = the starting sum Sarah earns + the increase in hourly pay.
And Sarah will earn A = $ 18.00 + $ 3.60 = $ 21.60 after the percentage increase.
Hence, an increase of $ 21.60 is required for hourly employment.

What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2

We can use the standard normal distribution to solve this problem by standardizing the values of 55 and 63:
z1 = (55 - 62) / 4 = -1.75
z2 = (63 - 62) / 4 = 0.25
Using a standard normal distribution table (or a calculator), we can find the area under the curve between z1 and z2:
P(-1.75 < z < 0.25) = 0.5466
Rounding to the nearest tenth of a percent, we get:
0.5466 ≈ 54.7%

Weight of the parcel in pounds = 1 pound
Step-by-step explanation:
Given:
y = 4x + 1 ---------------------Eq1
y = 3x + 2 ----------------------Eq2
Where,
x = weight of the parcel in pounds
y = total cost of the parcel
Find:
From Eq1 and Eq2, by using Substitution method.
y = 4x + 1 ---------------------Eq1
y = 3x + 2 ----------------------Eq2
So,
3x + 2 = 4x + 1
4x - 3x = 2 - 1
x = 1
Weight of the parcel in pounds = 1 pound in both services is equal
