Answer:
[tex]Percent = \frac{100a}{b}\%[/tex]
Step-by-step explanation:
Given
[tex]\frac{a}{b}[/tex]
Required
Convert to fraction
To do this, we simply multiply the fraction by 100%
This gives:
[tex]Percent = \frac{a}{b} * 100\%[/tex]
[tex]Percent = \frac{a * 100}{b}\%[/tex]
[tex]Percent = \frac{100a}{b}\%[/tex]
The expression cannot be further simplified.
Take for instance the fraction is: [tex]\frac{2}{5}[/tex]
Using the same analysis, the percentage would be:
[tex]Percent = \frac{2}{5} * 100\%[/tex]
[tex]Percent = \frac{2 * 100}{5}\%[/tex]
[tex]Percent = \frac{200}{5}\%[/tex]
[tex]Percent = 40\%[/tex]
Answer:
100(a divided by b)

Answer:
The first one: if 2/3 is 12 then 1/3 is 6. 3/3 is 18. SO Jane had 18 stuffed animals before the donation.
The second one: 25 students then 13 are men so 25-13 is 12. 12/25 as a percentage is 48%
Hope this helps!
Answer:
[tex]Section \: A. \\before \: the \: donation \ : jane \: had \: \boxed{18 \: (stuffed \: animals)} \\
Section B.\\
\boxed{the\: percentage\: of\: female\: student\: is\: \boxed{48 \%}}
[/tex]
Step-by-step explanation:
[tex]Section A.\\let \: the \: total \: animals \: be \to \: t_{a} \\ let \: the \: donated\: animals \: be \to \: d_{a} \\ then \to \\ if \: d_{a} = \frac{2}{3} (t_{a} ) : we \: can \: find \: t_{a} \: by \to \\ 12 = \frac{2}{3} (t_{a} ) \\ 2(t_{a} )= 12 \times 3 \\ t_{a} = \frac{36}{2} \\ \boxed{ t_{a} = 18.}
\\ \\
Section B.\\
let \: the \: total \: number\: of \: students\: be \: be \to \: t_{s} \\ let \: the \: number\: of \: male\: student\: be \: be \to \: m_{s} \\ then \to \\ if \: t_{s} = m_{s} +1 3 \: then \\
m_{s} = t_{s} -13\\
m_{s} = 25-13 \\
m_{s} =12 \\
hence \: percentage \: of \: girls \: is = \frac{12}{25} \times 100 \\
the \: percentage\: is \to \boxed{m_{s} = 48\%}

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of 0°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0°C (denoted by negative numbers) and some give readings above 0°C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. Find the temperature reading corresponding to the given information.
If 6.3% of the thermometers are rejected because they have readings that are too high and another 6.3% are rejected because they have readings that are too low, find the two readings that are cutoff values separating the rejected thermometers from the others.
–1.46° , 1.46°
–1.39° , 1.39°
–1.53° , 1.53°
–1.45° , 1.45°
Answer:
-1.53 , 1.53
Step-by-step explanation:
It is basically asking you to find the percentiles. so for the bottom 6.3% you would type into your calculator 2nd, VARS, invNorm, area: .063, mean: 0, and Standard Deviation: 1 which gives you -1.53.
for the upper 6.3% you have to take 1-.063=.937 to get the upper percentile. now type into your calculator 2nd, VARS, invNorm, area: .937, mean: 0, and Standard Deviation: 1 which gives you 1.53.
Using the normal distribution, it is found that the third quartile of Q3 is 0.67, hence option B –1.39°, 1.39° is correct.
What does "normal" describe in statistics?Normal usually refers to the word "normal" in a normal distribution.
The word normal is used when something occurs that has occurred frequently. The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from the mean, its chances decrease.
In a normal distribution with mean μ and standard deviation σ, the z-score of a measure X will be;
Z = (X - μ)/ σ
After finding the z-score, we have to find the p-value associated with this z-score, which is the percentile of X.
The mean is 0ºC, μ= 0
The standard deviation is 1ºC, σ = 1.
Therefore when Z has a p-value of 0.75, hence X when Z = 0.67.
Z = (X - μ)/ σ
0.67 = (X - 0)/ 1
X = 0.67
Thus, the two readings that are cutoff values separating the rejected thermometers from the others are B –1.39°, and 1.39°.

what are the possible degrees for the polynomial function
Answer:
Degree of the polynomial function = 5
Step-by-step explanation:
Since, the given graph of a polynomial has the x-intercepts at x = -2, -0.5, 0.5, 1.5, 3
Therefore, the equation of the polynomials with zero roots will be,
y = (x + 2)(x + 0.5)(x - 0.5)(x - 1.5)(x - 3)
When we solve this expression highest degree of the variable x will be 5.
Therefore, the possible degree of the polynomial function = 5
Answer:
i was going to screenshot the answer bc i got it right but its
"odd 5 degrees or greater" :)

what is an equation of the line that is parallel to y=-5x+6 and passes through the point (-4,-1)
Answer:
y= -5x - 21
Step-by-step explanation:
parallel lines have the same slope, so you know the slope.
you need to use the point slope formula y-y1=m(x-x1)
with this equation, this looks like y - -1 =- 5(x - -4)
double negatives are positives, so to keep this easier on the eyes, let's make it y + 1= -5(x + 4)
distribute the -5. you should get y + 1 = -5x - 20
subtract 1 to move it from the left side to the right and you get your answer!
y = -5x - 21

Given:
Seed below the ground = [tex]3\dfrac{1}{4}\text{ in.}[/tex]
Total length of plant = [tex]11\dfrac{1}{2}\text{ in.}[/tex]
To find:
The length of plane above the ground.
Solution:
We have,
Plant below the ground = [tex]3\dfrac{1}{4}\text{ in.}[/tex]
Total length of plant = [tex]11\dfrac{1}{2}\text{ in.}[/tex]
Plant above the ground = Total length of plant - Plant below the ground
[tex]=11\dfrac{1}{2}-3\dfrac{1}{4}[/tex]
[tex]=\dfrac{11\times 2+1}{2}-\dfrac{3\times 4+1}{4}[/tex]
[tex]=\dfrac{22+1}{2}-\dfrac{12+1}{4}[/tex]
[tex]=\dfrac{23}{2}-\dfrac{13}{4}[/tex]
Taking LCM, we get

[tex]=\dfrac{33}{4}[/tex]
[tex]=8\dfrac{1}{4}[/tex]
Therefore, the length of plant above the ground is [tex]8\dfrac{1}{4}\text{ in.}[/tex]
