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!

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 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
Determine the equation of the line described. Put answer in the slope-intercept form, if possible.

5x^4-7(-x)
Would the simplified version of this be 5x^4+7x?
Answer:
5x⁴ + 7x or x(5x³ + 7 )
Step-by-step explanation:
Given expression:
5x⁴ - 7(-x )
To simplify this expression, we have to follow the order of operation PEMDAS;
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
5x⁴ - 7(-x ) = 5x⁴ + 7x
Since x is common to both terms;
= x(5x³ + 7 )
So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )
A taxi charges $1.25 per mile and a flat fee of $2.75. How much would Maria pay for a 5 mile ride?
Answer:
9
Step-by-step explanation:
so you write the expression 2.75+1.25x= ?
If we subsitute the X for 5(miles) the we'll have the expression 2.75+1.25(5)= ?
and if you simplify that you will get 9.
Choose the correct rule to describe the transition of ▵ to ▵’’’
Answer:
The rule that describes the translation of ΔABC to ΔA'B'C' is
(x, y) → (x + 4, y + 3) ⇒ b
Step-by-step explanation:
Let us revise the rule of translation of a point
The image of the point (x, y) after translation h units to the right and k units up is (x + h, y + k)The image of the point (x, y) after translation h units to the right and k units down is (x + h, y - k) The image of the point (x, y) after translation h units to the left and k units up is (x - h, y + k)The image of the point (x, y) after translation h units to the left and k units down is (x - h, y - k)Let us solve the question
∵ Point A = (-3, 0)
∵ Point A' = (1, 3)
→ Subtract the x-coordinate of A from the x-coordinate of A' to find h
∵ h = 1 - - 3 = 1 + 3 = 4
→ h is a positive value, then the translation is to the right
∴ Point A translated 4 units to the right
→ Subtract the y-coordinate of A from the y-coordinate of A' to find k
∵ k = 3 - 0 = 3
→ K is a positive value, then the translation is up
∴ Point A translated 3 units up
∴ The rule of translation is (x, y) → (x + 4, y + 3)
Let us find B' and C' using the rule of translation
∵ B = (-3, -2)
∵ The rule of translation is (x, y) → (x + 4, y + 3)
∴ B' = (-3 + 4, -2 + 3)
∴ B' = (1, 1) ⇒ same as the figure
∵ C = (-1, -2)
∵ The rule of translation is (x, y) → (x + 4, y + 3)
∴ B' = (-1 + 4, -2 + 3)
∴ B' = (3, 1) ⇒ same as the figure
The rule that describes the translation of ΔABC to ΔA'B'C' is
(x, y) → (x + 4, y + 3)
In his garden tim plants the seed 3 1/4 in. Below the ground. After one month the tomato plant has grown a total of 11 1/2 in. How many inches is the plant above the ground?
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{46-13}{4}[/tex]
[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]
