Explanation:
[tex] \frac{-24}{7} [/tex] = -3 [tex] \frac{3}{7} [/tex] 
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.

Number 18 pls help me

Answers

Lila did it correctly. The answer is 324

Following PEMDAS, we first focus on the parenthesis. So we simplify 9-3 to get 6

So we go from 
18*4^2+(9-3)^2 
to 
18*4^2+6^2 

The next step is applying exponents. In this case, squaring the terms, so we go from
18*4^2+6^2 
to
18*16+36

Next is multiplying
18*16+36
turns into
288+36

Finally, add up 288 and 36 to get 288+36 = 324

That confirms that Lila is correct

----------------------

The error that Rob made is that he computed 18*4^2+9^2-3^2 but it is NOT correct. Saying (x-y)^2 = x^2-y^2 isn't a true equation for all x and y. Again you have to simplify what is in the parenthesis first, and then you can square it. Or you must use the FOIL rule to expand out (9-3)^2

A recipe for 6 dozen cookies calls for 3/4 cup of sugar. How much sugar is needed to make 4 dozen cookies? pls show all work and answer

Answers

So if 6 dozen cookies needs 3/4 cup of sugar, and we need to know how much sugar is needed to make 4 dozen, then find how much of 6 dozen 4 dozen is.

To do this, put it as a fraction:

4 dozen / 6 dozen, or 4/6, which is 2/3.

Since conveniently it calls for 3/4 cup of sugar, we can multiply that by 2/3, and we'll get 6/12, or 1/2.

So 1/2 cup of sugar is needed for 4 dozen cookies.

Holly missed 8 of 182 school days this year. Approximately what percent of school days was Holly in attendance?

Answers

Answer:

Wrong it is

Step-by-step explanation:

First, determine how many school days Holly attended.

182 - 7 = 175

Next, find the percentage of school days she attended.

175 ÷ 182 = 0.9615384615  96%

Holly attended approximately 96% of school days.

To calculate the percentage of school days Holly was in attendance, subtract the days missed from the total days and divide by the total days, then multiply by 100.

Holly missed 8 out of 182 school days this year. To find the percentage of days she was present, subtract the days missed from total days and divide by total days, then multiply by 100.

Days attended = 182 - 8 = 174Percentage attended = (174/182) * 100 ≈ 95.60%

Which number line represents all of the values of x for the equation x2 = 64?

Answers

x^2 = 64
x = + - 8

hope it helps

Answer:

We are asked to find all the values of x on the number line that satisfies the given quadratic equation:

[tex]x^2=64[/tex]

We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.

on taking the square root on both the side of the equation we obtain:

[tex]x=\pm 8[/tex]

Hence we get two points on the number line.

x=8   and x= -8.

These are the discrete values we did not get any interval of the solution.

How do I find the value of z?

Answers

Hello!

The answer is z = 16..

Solve it like this..

#1) Regroup terms

-3 = -7+z/4 ---> -3 = z/4 - 7

#2) Add 7 to both sides.

-3 = z/4 - 7 ---> -3 + 7 = z/4

#3) Do the addition.

-3 + 7 = z/4 ---> 4 = z/4

#4) Multiply both sides by 4.

4 = z/4 ---> 4 * 4 = z.

#5) Do the multiplication.

4 * 4 = z ---> 16 = z

An angle measures 102° less than the measure of a supplementary angle. what is the measure of each angle?

Answers

The measure of two angles are 141° and 39°.

What are supplementary angles?

When the sum of two angles equals to 180°, then those angles are said to be supplements of each other and hence called supplementary angles.

Given that, An angle measures 102° less than the measure of a supplementary angle.

Let the angles be x and y, then according to question,

x+y =  180°

x-y = 102°

Solving the equation by elimination method, we get,

2x = 282°

x = 141°

Put x = 141°

141°-y = 141°

y = 39°

Hence, the asked angles are 141° and 39°

#SPJ2

To find the measures of the angles, set up an equation using the property that supplementary angles add to 180 degrees. Solving the equation yields one angle measuring 39 degrees and the supplementary angle measuring 141 degrees.

When dealing with angles and their measurements, it's important to remember fundamental properties, such as the fact that the sum of supplementary angles is 180 degrees. Given that an angle is 102° less than its supplementary angle, we can set up an equation to find the measure of each angle. Let's call the first angle x; therefore, the supplementary angle will be x + 102°.

Using the property that the sum of supplementary angles is 180°, we can write the equation:
x + (x + 102°) = 180°
2x + 102° = 180°
2x = 180° - 102°
2x = 78°
x = 39°
Thus, the measure of the first angle is 39° and that of the supplementary angle is 39° + 102° = 141°.

A classic counting problem is to determine the number of different ways that the letters of "generally""generally" can be arranged. Find that number.

Answers

Final answer:

To determine the number of arrangements for the word 'generally', one calculates 9 factorial divided by the factorial of the counts of each repeated letter. With 'E' and 'L' repeating twice each, the calculation is 9! / (2! × 2!) resulting in 90720 unique arrangements.

Explanation:

Calculating Arrangements of the Word 'GENERALLY'

To calculate the number of different ways the letters in the word 'generally' can be arranged, we have to take into account the repeated letters. The word 'generally' has 9 letters with the following repetitions: G-1, E-2, N-1, R-1, A-1, L-2, and Y-1. The formula to calculate the permutations of a set of objects where there are duplicates is the factorial of the number of objects divided by the product of the factorials of the number of duplicates for each object.

Thus, to find the number of arrangements, we would calculate 9! (9 factorial) and then divide it by the product of the factorials of the repeated letters, which are E and L. This gives us 9! / (2! × 2!), or 362880 / (2 × 2), which simplifies to 90720 unique arrangements for the letters in 'generally'.

This combinatorial approach is a useful exercise in understanding how to count arrangements and can be applied more broadly to comprehend more intricate probability and statistics problems

The life expectancy of a typical lightbulb is normally distributed with a mean of 2,000 hours and a standard deviation of 27 hours. What is the probability that a lightbulb will last between 1,975 and 2,050 hours?

A. 0.17619
B. 0.32381
C. 0.79165
D. 0.96784

Answers

0.7916, so it would be c
The first standard deviation covers about 68% of the distribution in a normal curve. (34% higher, 34% lower than the mean). the second standard deviation covers 28% (14% between 1st and 2nd SD above the mean, 14% between 1st and 2nd SD below the mean).  In our case
1 Standard deviation = 27 hours (we will approximate to 25 hours)
Mean = 2,000 

This means that 34% of the distribution is between 1975 and 2000 hours       (within 1 standard deviation below the mean)

2,000- 2,050 covers the range within 50 hours above the mean.
50 hours is roughly 2 standard deviations. The second standard deviation (standard deviation between 1 and 2) covers around 14% on each side of the distribution.
50 hours is roughly 2 standard deviations, which means we add 34% + 14% = 48%. 
The range of 1,975 - 2,050 hours covers 34% of the distribution below the mean and 48% of the distribution above the mean. 
This means that the probability that the light bulb will last somewhere within this range is 34% + 48% = 82%

The closest answer is 79%. The difference can be explained by the fact that, for simplicity, we approximated the standard deviation to be ~25 hours instead of the real standard deviation of 27 hours.
