Answer:

No

Step-by-step explanation:

There are no numbers that can multiply by itself to get 50

Example of some perfect square:

4, 9, 16, 25, 36, 49, 64, 81, etc.

The expression (-9x)^4 can be represented as -6561x^3 without using exponents.

To express the expression (-9x)^4 without using exponents, we can expand it by multiplying the base (-9x) four times using the multiplication property.

(-9x)^4 = (-9x) * (-9x) * (-9x) * (-9x)

To simplify this expression, we can multiply the terms together, taking care to apply the rules of multiplication:

(-9x) * (-9x) = (-9 * -9) * (x * x) = 81 * x^2 = 81x^2

So, by substituting this result back into the original expression, we get:

(-9x)^4 = 81x^2 * (-9x) = -6561 x^3

Therefore, the expression (-9x)^4 can be represented as -6561x^3 without using exponents.

The z-score of 235.90, if a normal distribution of scores has a standard deviation of 182.56 and a mean of 265.95, is -0.165.

The mean of the set of data is equal to the sum of all the quantities in the data, and divide by the no of quantities.

Given:

The standard deviation, d = 182.56,

The mean, m = 265.95,

The observation value, X = 235.90

Calculate the z score by the following formula given below,

Z = (X - m) / d,

Here, Z is the Z score,

Z = 235.90 -  265.95 / 182.56

Z =  -0.165

Therefore, the z-score of 235.90, if a normal distribution of scores has a standard deviation of 182.56 and a mean of 265.95, is -0.165.

Step-by-step explanation:

I did the asignment and got it right

Answer:

See below.

Step-by-step explanation:

Hello!

The topic we should review for this problem is Order of Operations.

Order of Operations is a rule that identifies which part of an equation should be simplified first.

You might've heard of PEMDAS, where;

P for Parentheses, always first unless there's an exponent inside.

E for Exponent, simplified after the Parentheses.

M or D - Multiplication or Division after the Exponent(s).

A or S - Addition or Subtraction after Multiplication or Division.

\((5+3^2)+18\)

First we know that there's an Exponent inside the Parentheses, so we must evaluate that number first.

\((5+9)+18\)

Next, evaluate what's in the Parentheses.

\(14+18\\32\)

Our correct answer is 32.

We are asked what mistake did Raquel make, and what's the correct simplified version of the expression.

1a.) Raquel's mistake is combining unlike terms. It's impossible to combine together a natural number (5) and an exponential number. (3²)

Answer:

To find 29% of 150, we can first express 29% as a decimal by dividing 29 by 100. 29% is the same as 0.29.

Then, we multiply 0.29 by 150 to find the answer:

0.29 * 150 = 43.5

So, 29% of 150 is equal to 43.5.

Here's the work:

29% * 150 = 0.29 * 150 = 43.5

\(\huge\text{Hey there!}\)

\(\mathsf{29\%\ of \ 150}\)

\(\mathsf{= \dfrac{29}{100} \times \dfrac{150}{1}}\)

\(\mathsf{= \dfrac{29(150)}{100(1)}}\)

\(\mathsf{= \dfrac{4,350 \div 50}{100 \div 50}}\)

Step-by-step explanation:

Step-by-step explanation:

consider the cylinder standing upright.

we have to assume that 20.4 cm is the diameter of the circle.

it is not clear what dimension of the result is needed : cm³ or m³, cm² or m². it is important that we do our calculations always with the same dimension of all operands (don't mix apples and oranges in the same calculation).

the volume of such a cylinder (or any regular 3D object) is

base area × height

for a cylinder the base area is a circle :

pi × r²

r being the radius (half of the diameter).

so, we have

r = 20.4/2 = 10.2 cm

height = 22 m = 2,200 cm (1 m = 100 cm)

volume = pi × (10.2)² × 2200 =

= 719,072.8593... cm³ =

= 0.7190728593... m³

≈ 719,072.86 cm³

≈ 0.72 m³

for the surface of a cylinder we need to imagine to cut the cylinder open with straight cut from the top to the bottom and then put the result flat on the table.

this result is a rectangle.

length = height of the original cylinder.

width = circumference of the original cylinder (and its circular base) = 2 × pi × r

the surface area of the cylinder is then

2 × base circle area (top and bottom) = 2 × pi × r²

plus

the area of that rectangle

length × width = height × 2 × pi × r

that is

height×2×pi×r + 2×pi×r² = 2×pi×r×(height + r)

in our case now

surface area = 2×pi×10.2×(2200 + 10.2) =

= pi×20.4×2210.2 =

= 141,648.3809... cm² =

= 14.16483809... m²

≈ 141,648.38 cm²

≈ 14.16 m²

remember, because

1 m = 100 cm

then

1 m² = 1 m × 1 m = 100 cm × 100 cm = 10,000 cm²

1 m³ = 1 m × 1 m × 1 m = 100 cm × 100 cm × 100 cm =

= 1,000,000 cm³

The false statement from the stem-and-leaf plot is given as follows:

b. The data for Paul’s group has two modes.

The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:

The mode of a data-set is the data-set that appears the most times in a data-set.

Hence, for Paul's group, the mode is given as follows:

As it is the only observation that appears the times, hence the data has one mode, and option b gives the false statement.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.
