Answers

Answer:  see below

Step-by-step explanation:

Write each equation in y = mx + b format where m is the slope and b is the y-intercept.

Left side: -4 ≤ x < -1

If you continue the line through the y-axis it will pass through (0, 4) --> b = 4

The rise over run is -1 over 1 --> m = -1

y = (-1)x + (4)   -->    y = -x + 4

Right side: -1 < x < 4

The line passes through (0,0) --> b = 0.

The rise over run is -1 over 1 --> m = -1

y = (-1)x + (0)    -->    y = -x

Answer:

Measured and Counted.

Step-by-step explanation:

Continuous data are usually “Measured”, but discrete data are usually “Counted”.

The continuous data are the data that can be measured, for example, Height of children, time in the race, length of leaf, etc. In this case, the data is taken within the range. While the discrete data is the data that can be counted. For example, the number of employees in the office, the number of students in the school, the result of rolling dice, etc. In this case, the data is a fixed number. Accordingly, the continuous data is measurable and discrete data is countable.

At a concert 60% of the audience are adults . 25% of those remaining are boys and the rest of the audience members are girls .There are 30 girls altogether. How many a people are the at the concert?

Answers

Answer:

1800 people were at the concert.

Hello there! :D

Its math time!!

Alright, let's write out all the percentages.

60%= adults

25%= boys

There are thirty girls.

We can find out what percentage of the people there are girls by adding the percentages of the adults and boys and subtracting that from 100.

60+25= 85

100-85=15

So, 15% of the audience are girls. That is equal to 30 people.

I also know that 60 is divisible by 15 and 4. So, if we multiply 30 by 4 we can find out how many adults are at the concert.

30*4= 120 adults

We can also take 15 and divide it by 3 (as well as 30)  so we can find out how many people there are for 5% of the concert. That will make it easier to find out how many boys there are.

15/3= 5%

30/3=10

Now we just need to know how many fives go into 25, which is 5.

5*10= 50

Add that to the number of adults and girls:

50+120+30= 200 people

There are 200 people at the concert!

If you go on a road trip of 270 miles in the mountains and 7/ 10 of the trip is downhill, how many miles of the trip are not downhill? Reduce to the lowest terms.

Answers

Answer:

81 miles

Step-by-step explanation:

From the question 7/10 of the trip has been said to be downhill. It therefore means that 3/10 is not downhill.

Miles = 270

Downhill = 7/10

Not downhill = 3/10

Now we have To calculate Miles that are not downhill (uphill)

But first I calculated for the number of downhill miles

270x7/10

Downhill = 189 miles

To get the number of not downhill miles

I subtracted 189 from the total number of miles on the question.

270 - 189

= 81 Miles.

Therefore 81 Miles of the trip are not downhill.

If you have anymore questions or need clarity please let me know on the comment section. Thank you and Good luck!

270 miles
7/10 downhill

270 x 3/10
810/10
81 miles
Or
270 x 7/10
1890/10
189 miles downhill

270 - 189 = 81 miles

Answer:

[tex]u<-1\text{ or } u>2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]-3|2-4u|+5<-13[/tex]

First, subtract -5 from both sides:

[tex]-3|2-4u|<-18[/tex]

Divide both sides by -3. Since we are dividing by a negative, we will flip the sign:

[tex]|2-4u|>6[/tex]

Definition of absolute value:

[tex]2-4u>6\text{ or } 2-4u<-6[/tex]

Note that we flip the sign on the right because we multiplied 6 by a negative.

On both the left and right, subtract 2:

[tex]-4u>4\text{ or } -4u<-8[/tex]

Divide both equations by -4. Since we're dividing by a negative, flip the signs:

[tex]u<-1\text{ or } u>2[/tex]

So, our final solution is:

how much dose the least expensive 50 present of trail mix cost? what is the least of 4 pounde of trail mix can cost

Answers

does* what is this question it’s 15$

The box-whisker plot is missing. Check the attachment for the data.

The least expensive 50% of trail mix costs between $1.25 and $2.75 per pound, as these, depict the minimum point and the median (50% of data), of the given box-whisker plot.

The least 4 pounds of trail mix can cost $6.00, at the minimum rate shown in the box-whisker plot by its starting point of $1.25 per pound.

What is a box-whisker plot?

A box-whisker plot is a diagrammatic representation of data. The whiskers start from the minimum data and go up to the maximum. In between the whiskers is a box that starts from the first quartile of the data (below which 25% of the data lies) and goes up to the third quartile (below which 75% of the data lies). In between the box is a line, that indicates the median of the data. The median is the value of the middlemost data.

How to solve the given question?

In the question, we are given a box-whisker plot, showing the different costs of trail mix at different prices per pound.

1. We are asked how much the least expensive 50% of trail mix costs.

We know that 50% of data is depicted at the median which is the line in between the box in a box-whisker plot. So the least expensive 50% is shown before the line.

The minimum point in the data is $1.25 and the median is $2.75.

Hence, the least expensive 50% of trail mix costs between $1.25 and $2.75 per pound, as these depict the minimum point and the median (50% of data), of the given box-whisker plot.

2. We are asked to find the least cost of 4 pounds of the trail mix.

We know that the starting point of the whisker shows the minimum point in the data. Hence, the least cost of the trail mix is $1.25 per pound.

So, the cost of 4 pounds is $1.25 * 4 = $6.00.

Hence, the least 4 pounds of trail mix can cost $6.00, at the minimum rate shown in the box-whisker plot by its starting point of $1.25 per pound.

So, it is like:

You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the number of dimes. Is your friend correct? Let d represent the number of dimes

An equation that models this situation is _____=2.80
(I’m so stupid help)

Answers

Answer:

Step-by-step explanation:

d = number of dimes

2.80 = 0.1d + 0.25 (d + 8 )

2.80 = 0.1d + 0.25d + 2            Combine like terms

2.80 = 0.35d + 2                       Subtract 2 from both sides

0.80 = 0.35d                             Divide both sides by 0.35

d ≈ 2.29

No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
