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.

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)

Answer:

(-3, 5)

Step-by-step explanation:

im assuming the orginal point q is (5, 3)

Based on the given scenario above, the coordinates of point Q  is known to be (-3, 5).

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)

S(2, 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:

Q(5, 3)  = Q'(-3, 5)

Therefore, the coordinates of point Q' is:  Q'(-3, 5)

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.

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.

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.

The addition of 3a^2 + a^2 to a + 6 gives 3a^2 + a^2 + a +6.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

Simplification usually involves making the expression simple and easy to use later.

We have to find when 3a^2 + a^2 added to a + 6.

This cannot be added further because they do not have any like terms.

Since those terms are not like terms, their coefficient won't be add and the expression we've got right now, is its simplest form and cannot be reduced more.

Those terms which have same variables raised with same power are like terms.

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.
