4 The side lengths of a square are each 5p. By adding 1 to the length and subtracting 1 from the width, a rectangle is made. What is the area of the rectangle?
4p2-2
0 25p2 + 1
25p2 - 10p - 1
25p - 1
its 25p^2-1
Step-by-step explanation:
the two sides are (5p+1) and (5p-1) so just multiply them

9514 1404 393
Answer:
x = 19
Step-by-step explanation:
Corresponding sides are proportional.
full length/right segment = 36/20 = (x+5+30)/30
Multiplying by 30 gives ...
54 = x +35
19 = x . . . . . . . subtract 35

Answer:
That would be A my good Sir (or ma'am).
Step-by-step explanation:
A triangle has a total of 180 degrees in it , however we already know one side is 45, so we can add that to the solution, we also know that 2 sides are the exact same, so therefore, we will be multiplying our unknown value ( x = 67.5 btw, not so unknown) by 2, and you will always get 180 degrees, thats how you check your answer, also if you sbutract 45 from 180 and divide the product by 2 you will get the value of x ( which is 67.5).
Thats It Helps It Helps!
find value of x also the answer choices are
a. 62.5
b. 9.65
c. 71.35
d. 103.25
Answer:
D.103.25
Step-by-step explanation:
To find the value of x, you need to know that the height of the donkey and the cactus are proportional and that the shadow of the donkey and cactus are also proportional to each other. Thus, you need to create a proportional and cross multiply to find the value of x.
x/59 = 7/4
After you cross multiply, the equation should look like this:
4x=413
Finally, you divide both sides or numbers by 4 to get 103.25 as your answer! Hope this helps!
Which of the following points below represents (- 2, - (5pi)/4) the polar grid?
Answer:
Well, when we have a point in rectangular coordinates (x, y) and we want to write it in polar coordinates (r, θ) the rule we use is:
r = √(x^2 + y^2)
θ = Atg(Iy/xI) + 90°*(n - 1)
where n is number of the quadrant where our point is.
For example, if we are on the second quadrant, we use n = 2.
Now, if instead, we have the point (r, θ) and we want to rewrite it in rectangular coordinates, then the transformation is:
x = r*cos(θ)
y = r*sin(θ)
Now we have the point (- 2, -(5pi)/4) because the first part is negative, this number can not be in polar coordinates (r can not be negative) then we have:
x = -2
y = -(5*pi)/4
Using the first relation, we can find that:
r = √( (-2)^2 + (-5*3.14/4)^2) = 4.4
(rememer that the point (- 2, -(5pi)/4) is on the third quadrant, then we will use n = 3.)
θ = Atg(-(5*pi)/4/-2) + 90°*(3 - 1)= Atg((5*pi)/2) + 180° = 82.7° + 180° = 262.7°
Then the point that represents (- 2, - (5pi)/4) in polar coordinates is the point:
(4.4, 262.7°)
If instead of degrees, the angle part is written in radians, we have:
180° = 3.14 radians.
262.7° = x radians.
then:
x/3.14 = (262.7)/180
x = 3.14*(262.7)/180 = 4.58 radians.
then the point will be:
(4.4, 4.58 radians)
What number does 4 and 8 share in adding mixed numbers unlike denominators
Answer:commen factoers is what you need 2 4 8 16 and so on
Step-by-step explanation:
To add mixed numbers, we first add the whole numbers together, and then the fractions. ...
If the denominators of the fractions are different, then first find equivalent fractions with a common denominator before adding. ...
Subtracting mixed numbers is very similar to adding them.

At a party, the punch bowl is hemispherical, with 2 foot radius and open at the top. The fruit punch weighs 66 pounds per cubic foot. At the beginning of the party the bowl is full to the brim. The rules for serving punch require each person to fill the ladle, raise it exactly 1 foot above the top of the owl (without spilling!), and then pour the punch into a cup at that level. After 10 minutes, 30 people have filled 30 cups, and the punch remaining in the bowl is 4 inches deep. Draw a picture of the situation, and then set up the integral for the work W involved in raising the punch until the punch remaining in the bowl has a depth of only 4 inches. Include all pertinent information in the integral, but do not evaluate the integral.
Answer:
W = ∫ [−2/3 to 0] 66π (2−y)(1−y²) dy = 2332π/27
Step-by-step explanation:
Vertical cross-section of bowl is a semi-circle of radius 1, centered at (0,0)
x² + y² = 1 (for y ≤ 0)
Bottom of bowl is at y = −1
Top of bowl is at y = 0
When punch is 4 inches deep, this 1/3 ft above bottom of bowl:
y = −1+1/3 = −2/3
So we integrate from y = −2/3 to y = 0
Radius of cross section at height of y is = x = √(1−y²)
Area of cross section at height y is πr²= πx² = π(1−y²)
Since each person is to lift ladle 2 feet above the top of the bowl, then distance = 2−y
W = Σ (density of punch * distance * volume of punch)
W = ∫ [−2/3 to 0] 66 * (2−y) * πr² dy
W = ∫ [−2/3 to 0] 66π (2−y)(1−y²) dy = 2332π/27
la tercera parte de la suma entre un numero y 5 es 4
Me ayudan?
Respuesta:
si lo que estás buscando es "el número", la respuesta es es "7"
Explicación paso a paso:
si nos dice que la tercera parte de una cifra es "4" debemos hacer lo siguiente:
4*3=12 (para sacar el resultado de la suma)
verificamos diviendo 12 entre su tercera parte: 12 entre 3=4
a 12 le restamos 5 para sacar el número que necesita la suma 12-5=7
entonces la tercera parte de la suma entre 7+5 ó bien 12, es 4
7+5=12 12 entre 3=4

She replaced the balls and repeated this process for a total of 505050 trials. Her results are summarized in the dotplot below, where each dot represents the sample IQR from a sample of 555 balls. 00551010151520202525Sample IQR Based on these results, does sample IQR appear to be a biased or unbiased estimator of population IQR
Answer: Sample IQR appears to be a biased estimator since it consistently underestimated the population IQR.
Step-by-step explanation: Checked by Khan Academy
Sample IQR appear to be a biased estimator of population IQR.
What is a biased estimator?
An estimate that deviates from the genuine population value is said to be biased. If the kind and extent of the bias are known, a biased sample may still be informative. When a sample's value matches the actual value of a population parameter, that is an unbiased estimator.
Matilda was curious if sample interquartile range (IQR) was an unbiased estimator of population IQR.
She placed ping pong balls numbered from 0 to 32 in a drum and mixed them well.
The IQR of the population is 16.
She then took a random sample of 5 balls and calculated the IQR of the sample.
She replaced the balls and repeated this process for a total of 50 trials. Her results are summarized in the dot plot below, where each dot represents the sample IQR from a sample of 5 balls.
Sample range appears to be a biased estimator since it consistently underestimated the population range.
The sample ranges appear to be centered below 32.
Therefore, the sample IQR is a biased estimator.

Step-by-step explanation:
The state of Georgia has several statewide lottery options. One of the simpler ones is a "Pick 3" game in which you pick one of the 1000 three-digit numbers between 000 and 999. The lottery selects a three-digit number at random. With a bet of $1, you win $390 if your number is selected and nothing ($0) otherwise.
(a) With a single $1 bet, what is the probability that you win $390?
(b) Let x denote your winnings for a $1 bet, so x = $0 or x = $390. Construct the probability distribution for X. Use 3 decimal places.
(c) The mean of the distribution equals ___________ X cents for the dollar paid to play.
(d) Would this be considered a gain for you?
No. For every $1 I pay, I will lose $0.39 on average.
No. For every $1 I pay, I will lose $ 0.61 on average.
Yes. For every $1 I pay, I will win $0.39 on average.
(e) If you play "PICK 3" 100 times, how much should you expect to lose?
Answer:
1/ 1000 ;
X : _____ 0 ___________ 390
P(x) : ___ 999/1000 ___ 1/ 1000 ;
0.39 ;
D ;
-$61
Step-by-step explanation:
1.)
Probability of winning with a single bet:
Winning numbers in lottery = 1
Lottery size = 1000
P(winning per bet) = 1/ 1000
2.)
X : _____ 0 ___________ 390
P(x) : ___ 999/1000 ___ 1/ 1000
3.)
Σx*p(x)
(0 * 999/1000) + (390 * 1/1000)
0 + 390 / 1000
= 0.39
4)
Expected winning :
Loss = - 1 * 999/1000 ; win = 390 * 1/1000
- 0.999 + 0.39 = - 0.609 = - $0.61
Hence, on average, for every $1 bet, I lose $0.61 on average
E.)
Expected winning for playing 100 times ;
Loss per play:
Expected winning * 100
-$0.61 * 100 = -$61
Loss of - $61 on average

Answer:
×=1/3
Step-by-step explanation:
8x –3(5x–2)=7–10x
Distribute
8x - 15x +6 = 7-10x
Combine like terms
-7x + 6 = 7- 10x
Add 10x to each side
-7x +10x+ 6 = 7- 10x+10x
3x+6 = 7
Subtract 6 from each side
3x+6-6 =7-6
3x = 1
Divide each side by 3
3x/3 = 1/3
x = 1/3
