True or false 0.20 is equivalent to 2/100
Answer:
0.02 is equivalent to 2/100
therefore it is false
if i can have brainliest that would be great
Final answer:
The statement that 0.20 is equivalent to 2/100 is false. The correct equivalent fraction of 0.20 is 20/100, which simplifies to 1/5.
Explanation:
The question asks whether 0.20 is equivalent to 2/100. This is false. The decimal 0.20 is equivalent to 20/100, which simplifies to 1/5 when you divide the numerator and the denominator by the greatest common divisor, which is 20 in this case. To convert a decimal to a fraction, place the decimal number over its place value. Since there are two digits to the right of the decimal point in 0.20, you would put 20 over 100, which reduces to 1/5. On the other hand, 2/100 cannot be simplified further and remains as is. Thus, 0.20 is not equivalent to 2/100; it is actually ten times larger.

(SAT Prep) In the figure, what is the length of BC?
A. 25
B. 15
C. 18
D. 22
Answer:
I got 18 as my answer
Step-by-step explanation:
I made a triangle with the right side by dropping a vertical. Lets call the point straight down from C, E
Then I found the angle of D
sin θ = 5/13
θ = sin-¹(5/13)
θ≅22.619°
Then I found length of DE by
cosθ (remember we know what theta is) = X/13
12cosθ = X
X = 12
The length of DE is 12.
Since AD is 30, and the left side has two right angles we can do
AD - DE to find BC.
30-12 is 18
The length of BC is C. 18.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given is a trapezoid.
First draw a perpendicular line from C to the segment AD.
Mark the intersecting point of line and AD by P.
We know that,
CP = BA = 5
Using Pythagoras theorem,
PD = √(13² - 5²) = √(169 - 25) = √144 = 12
Now, AP + PD = AD
AP = AD - PD
= 30 - 12
= 18
Now, BC = AP = 18.
Hence the length of BC is 18.

PQ⊥PS , m∠QPR=7x−9, m∠RPS=4x+22
Find : m∠QPR
Given:
It is given that,
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the value of ∠QPR.
Formula
As per the given problem PR lies between PQ and PS,
So,
∠QPR+∠RPS = 90°
Now,
Putting the values of ∠RPS and ∠QPR we get,
[tex]7x-9+4x+22 = 90[/tex]
or, [tex]11x = 90-22+9[/tex]
or, [tex]11x = 77[/tex]
or, [tex]x = \frac{77}{11}[/tex]
or, [tex]x = 7[/tex]
Substituting the value of [tex]x = 7[/tex] in ∠QPR we get,
∠QPR = [tex]7(7)-9[/tex]
or, ∠QPR = [tex]40^\circ[/tex]
Hence,
The value of ∠QPR is 40°.
Tim purchased a random sample of clementines at a local grocery store. The 95% confidence interval for the mean weight of all clementines at the store is 76.6 grams to 90.1 grams. Interpret this confidence interval.
Answer:
Step-by-step explanation:
Confidence interval is constructed to provide an estimated for an unknown population parameter such as the mean and sometimes, the standard deviation. It is expressed as
Sample mean ± margin of error
From the confidence interval given, the lower boundary is 76.6 grams while the upper boundary is 90.1 grams. Therefore,
It means that we are 95% confident that the mean weight of all clementines at the store lies between 76.6 grams to 90.1 grams. Also, 95% of the confidence intervals constructed in this way would contain the true value for the population mean weight of all clementines at the store.
Final answer:
A 95% confidence interval for the mean weight of clementines at a local grocery store ranging from 76.6 to 90.1 grams means we are 95% confident the true average weight of all clementines falls within this range. This range is based on a random sample and provides an estimate of the population mean. The width of the interval reflects the estimate's precision.
Explanation:
A 95% confidence interval for the mean weight of clementines, which ranges from 76.6 grams to 90.1 grams, means that we are 95% confident that the average weight of all clementines available in the store falls within this range. This interval was determined based on a random sample of clementines purchased, which serves as a representative subset of the entire clementine population in the store.
The concept of a confidence interval allows researchers and statisticians to estimate the true mean of a population based on sample data. In this case, unless the true average weight of the clementines lies outside this range, which has only a 5% probability (100% - 95%), we can assume that our interval includes the true mean weight of all clementines in the store. This interpretation is common in statistics and is crucial for making informed decisions or predictions based on sample data.
The width of the confidence interval, from 76.6 to 90.1 grams, reflects the precision of our estimate. A narrower interval would indicate a more precise estimate of the true mean weight, but increasing precision usually requires a larger sample size or a more homogeneous population. The principles behind confidence intervals are fundamental in various fields, including scientific research, engineering, and business analytics, to make reliable inferences about population parameters based on sample statistics.

A. Describe the error in the expression Cait used for her calculation.
B. Show or explain how you would calculate the total cost of Cait's purchase.
Type your answers in the space provided.
Answer:
A. Cait treated the discount as an increase
B. (20) (1.06) (0.85)
Step-by-step explanation:
Hi, Cait treated the discount as an increase.
Cait multiplied the price (20) by the tax percentage (increase) 1.06
Since the sale tax increase is 6% and it is added to the price we have to express it in decimal form (6/100=0.06) and add it to 1.
20 (1 +0.06) = 20 (1.06)
The coupon discount is subtracted to the price. So, the correct form is:
15/100= 0.15
20 (1-0.15) = 20 (0.85)
Instead of this, Cait expressed the percent discount as a percent increase .
20 (1+0.15) = 20 (1.15)
The correct form is (20) (1.06) (0.85)
2/7 converted to percentage

by a dog with a neck circumference of
12.5 inches? Explain.
Answer:
No. The collar should not be worn by this dog.
Step-by-step explanation:
Please kindly go through the attached files for more explanation.
Final answer:
the collar is too small for the dog.
Explanation:
To answer whether the dog collar should be worn by a dog with a neck circumference of 12.5 inches, we must consider the information given: the dog's collar adjusts between a circumference of 10 and 14 inches and it should be at least 0.5 inch larger than the dog's neck circumference.
First, we calculate the radius of the dog's neck using the formula for circumference: C = 2πr. For a neck circumference of 12.5 inches, the radius (r) would be:
C = 2πr
12.5 = 2πr
r = 12.5 / (2π)
r ≈ 1.9875 inches
Now, to ensure comfort, the collar's radius should be at least 0.5 inch greater than the dog's neck radius. Adding 0.5 inch to the dog's neck radius gives us:
1.9875 inches + 0.5 inch = 2.4875 inches
Which means the collar's circumference should be at least:
C = 2πr
C ≈ 2π(2.4875)
C ≈ 15.63 inches
Given that the collar adjusts to a maximum of 14 inches, this would be too small for a dog with a neck radius as calculated. Therefore, the collar should not be worn by a dog with a neck circumference of 12.5 inches, as it would not accommodate the extra 0.5 inch needed for comfort.

Based on the given scenario above, the coordinates of point Q is known to be (-3, 5).
What is the points about?Note that if a point P(x, y) is rotated 90° counterclockwise around the origin, one has to flip x and y and reverse the sign of y.
So, The rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin is said to be:
P(x, y) = P'(-y, x)
In this question, rectangle PQRS is rotated 90° counterclockwise about the origin.
The rectangle is said to have the coordinates:
P(2, 3)
Q(5, 3)
R(5, 1)

Therefore we look for the coordinates of the point Q’.
By using the rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin, then:
P(x, y) = P'(-y, x)
Therefore, coordinates of the point Q’ will be:

One zip Weighs as much as three zaps two zaps weight as much as five zowies three zowies weigh as much as two swooshes if one weighs sixty pounds how much does a zip weigh
Answer:1 zip weighs 30 lb
Step-by-step explanation:
3 zowies = 12 lb. so, 1 zowie = 4 lb.
2 zap = 20 lb. so, 1 zap = 10 lb.
1 zip = 30 lb.
One zip weighs 360 pounds.
1. One zip weighs as much as three zaps.
2. Two zaps weigh as much as five zowies.
3. Three zowies weigh as much as two swooshes.
4. One swoosh weighs 60 pounds.
We need to find the weight of one zip.
Step 1: Find the weight of one swoosh.
Since one swoosh weighs 60 pounds, we have:
1 swoosh = 60 pounds
Step 2: Find the weight of three zowies.
Since three zowies weigh as much as two swooshes, and one swoosh weighs 60 pounds, we have:
3 zowies = 2 swooshes = 2 * 60 = 120 pounds
Step 3: Find the weight of two zaps.
Since two zaps weigh as much as five zowies, and three zowies weigh 120 pounds, we have:
2 zaps = 5 zowies = 120 pounds
Step 4: Find the weight of one zip.
Since one zip weighs as much as three zaps, and two zaps weigh 120 pounds, we have:
1 zip = 3 zaps = 3 * 120 = 360 pounds
