Answer 1

Answer:

The solution for the system of equations is (2, 4). This means that for February, both the number of imports and the number of exports was 4.

Step-by-step explanation:

Again, remember that the solutions for a system, in this case two charts, are where the outputs (exports) are the same.

We can see that the exports for both f(x) and g(x) are the same for the month of February (second month).

This means that the solution to our system of equations is (2, 4).

So, the solution means that for the second month February, the number of imports was equivalent to the number of exports: both are 4.

(And lastly, out of the four months given, only February had the same number of imports and exports.)

For Field Day, the 72 students in fourth grade will be divided into tears with the same number of students on each team. The 60 students in third grade will be divided into teams that each have the same number of students as the fourth grade teams. What is the largest number of students that a team could have? Help meeee

Answers

Here, we have to see what the greatest common factor between 60 and 72 could be.
We do this because the factors are the numbers determining the number of people and the number of teams, for example if they used the factors 6 and 10 for 60, they would make 6 teams of 10 people. And since factors are whole numbers, it makes sense for people and doesn’t cut ppl in half.
So the greatest factor that 72 and 60 gave have in common is 12, bc 5 x 12 is 60 and 6 x 12 is 72, and they don’t have other factors in common that are higher than 12.
This means that 12 is the answer, bc it’s the largest number of students that a team could have, in both the fourth and third grades.

A bakery produces 280 loaves of bread and 95 cakes daily.
explain how you would compute the percent of the baked foods that are cakes.

Answers

The percent of the baked foods that are cakes will be 25.33%

How to calculate the percentage?

It should be noted that a percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100.

The percentage then refers to a component per hundred. The word percentage simply means per 100 and it is represented by %. In this situation, the bakery produces 280 loaves of bread and 95 cakes daily.

The percent of the baked foods that are cakes will be:

= Number of cakes / Number produced daily × 100

= 95 / (280 + 95) × 100

= 95 / 375 × 100

= 25.33%

report error suppose the ratio of lev's age to mina's age is $1 : 2$ and the ratio of mina's age to naomi's age is $3 : 4$. if the sum of all three ages is between $30$ and $50$, then how old is mina? note: all ages are calculated to the nearest whole year.

Answers

As per the given ratio Mina's age is 12 years old.

Ratio in math is defined as shows how many times one number contains another.

Here we have given ratio information as written as

=> Lev's age : Mina's age = 1 : 2

And the ratio between is written as

=> Mina's age : Naomi's age = 3 : 4

Here we have given the condition that the sum of all three ages is written as,

=> Lev + Mina + Naomi = 30 to 50

Here let us consider Lev's age as L, Mina's age as M and Naomi's age as N

Then the ratio is calculated as,

=> L = 1/2M

=> N = 4/3M

And the sum of all value is written as

=> L + M + N = 30 to 50

When we apply the values on it, then we get,

1/2M + M + 4/3M = 30 to 50

When we simplify it by multiply all by 6, then we get

=> 3M + 6M + 8M = 180 to 300

=> 17M = 180 to 300

Therefore, here we have to find a number between 180 and 300 that divisible by 17 and 6.

So let us consider that that number is 204.

Then the value of M is calculated as,

=> 17M = 204

=> M = 12

Complete question:

A right triangle A right triangle has a hypotenuse of 24 cm and a height of 16 cm. What is the approximate perimeter of the triangle?

Answers

The approximate perimeter of the right triangle is 57.89 cm.

To find the perimeter of the right triangle, we need to know the lengths of the other two sides.

Let's use the Pythagorean theorem, which asserts that the hypotenuse (the longest side) of a right triangle has a square whose sum is equal to the squares of the other two sides.

In this case, we know the length of the hypotenuse is 24 cm and the height (one of the other sides) is 16 cm. Let's call the third side x.

So we have:

$24^2 = 16^2 + x^2$

Simplifying, we get:

$576 = 256 + x^2$

Subtracting 256 from both sides, we get:

$320 = x^2$

Taking the square root of both sides, we get:

x ≈ 17.89

So the approximate perimeter of the triangle is:

P = 24 + 16 + 17.89 ≈ 57.89 cm

A password with 6 characters is randomly selected from the 26 letters of the alphabet.

What is the probability that the password does not have repeated letters, expressed to the nearest tenth of a percent?

Answers

We can see here that the probability that the password does not have repeated letters, expressed to the nearest tenth of a percent is = 9.8%.

What is probability?

Probability is a measure of how likely an event is to happen. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.

The probability of an event can be calculated using the following formula:

Probability = Favorable Outcomes / Total Outcomes

The number of possible passwords is:

26 × 26 × 26 × 26 × 26 × 26 = 308,915,776.

The number of passwords with no repeated letters is

26P6 = 30,260,000.

The probability of a password having no repeated letters is

= 30,260,000 / 308,915,776 = 0.09779 = 9.78%.

Null hypothesis: The mean number of points scored by the taller team is not significantly different from the population mean of 72.

How did we determine the test statistic?

Alternative hypothesis: The mean number of points scored by the taller team is significantly greater than the population mean of 72.

Since the population variance is unknown, we will use a t-test. The degrees of freedom for this test will be 9 (n-1), where n is the sample size of the taller team (10).

Using an alpha level of 0.05 and 9 degrees of freedom, the critical t-value is 1.833.

To calculate the test statistic, we first need to find the sample mean and standard deviation of the taller team's scores. The sample mean is 82, and the sample standard deviation is 9.89. Using these values, we can calculate the t-value:

t = (82-72) / (9.89 / sqrt(10)) = 3.19

Since the calculated t-value (3.19) is greater than the critical t-value (1.833), we reject the null hypothesis and conclude that there is a significant difference between the mean number of points scored by the taller team and the population mean of 72. The coach can therefore conclude that having a taller team does result in a greater number of points scored.

Option B is a correct representation of the given number line, -3.8 < 1.5, and is located to the left of 1.5.

What is a number line?

A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is thought to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers.

Given a number line and two points marked on it,

-3.8 and 1.5

we find from the number line that -3.8 lie left to 1.5,

and the negative numbers are always less than the positive numbers,

so -3.8 is less than 1.5,

-3.8 < 1.5, and lie left to 1.5.
