Answer:

[tex]\frac{4}{5\\}[/tex]

Step-by-step explanation:

So, when dividing fractions, all you have to do is flip the second fraction and multiply. Like this:

[tex]\frac{2}{3}[/tex] × [tex]\frac{6}{5}[/tex] = [tex]\frac{12}{15}[/tex]

After that, all you have to do is simplify that fraction. Like this:

[tex]\frac{12}{15}[/tex] ÷ [tex]\frac{3}{3} \\[/tex] = [tex]\frac{4}{5\\}[/tex]

If 50 people can fit into 6 rooms. How many people
fit into 42 rooms?

Answers

Answer:

350 people can fit into 42 rooms

Step-by-step explanation:

So we can write it as a relation fraction equation:

[tex]\frac{50}{6}=\frac{x}{42}[/tex]

Where:

x represents the people can fit in 42 rooms

[tex]x=\frac{50*42}{6}[/tex]

[tex]x=350[/tex]

Therefore, 350 people can fit into 42 rooms.

solve 35% of 84 using the mental method

Answers

Answer:

29 approximately

Step-by-step explanation:

You want to estimate 35% of 84.  35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28.    Use a calculator to find 0.35(84):  29.4.     This 28 is a fairly good estimate of 35% of 84 which is 29.4.

What is the equation of the line that passes through the point (3,-2) and has a
slope of -22

Answers

Answer:

y = -2x + 4

Step-by-step explanation:

slope intercept form:

y = mx + b

m = slope = -2

b = y-intercept

x = x = 3

y = y = -2

Plug in the corresponding numbers to the corresponding variables:

-2 = (-2) * (3) + b

Simplify. First, multiply:

-2 = (-6) + b

Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:

-2 (+6) = -6 (+6) + b

b = -2 + 6

b = 4

Plug in 4 for b in the equation:

y = mx + b

y = -2x + 4

Please help with this!!! I’ll give Brainliest!!!

Answers

Answer: y = 70° x = 110°

Steps:
X and the angle 110° correspond to eachother so x must equal 110°

110 + 110 + y(2) = 360
220 + y(2) = 360
y(2) = 360 - 220
y(2) = 140
y = 70

Check:
70 + 70 + 110 + 110 = 360
140 + 220 = 360
360 = 360 ✅

Thanks. The upcoming championship high school football game is a big deal in your little town. The problem is, it is being played in the next biggest town, which is two hours away! To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:6 5 5 5 3 2 3 6 2 25 4 3 3 4 2 5 3 4 5You and your partner will construct a 90% confidence interval and 95% confidence interval for the mean number of students who share a ride to school, then you will compare and interpret the results.Part A: Decide which partner will construct each confidence interval, and then state the parameter and check the conditions. Part B: Construct the confidence interval. Be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process. Part C: Interpret the meaning of the confidence interval, and describe the difference in the width of the interval and the margin of error.
