Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.

Answer:

I think x is 60 and y is 50.

Step-by-step explanation:

70 + 50 = 120

180 - 120 = 60

x = 60

50 + 50 = 100

70 + 60 = 130

130 + 100 = 230

230 - 180 = 50

y = 50

Astrid travels 130 km in 2 hours and then at 85 km/h for another 3 hours to reach her

Pie

Answer:

$\huge\boxed{\sf Speed = 77\ km/hr}$

Step-by-step explanation:

<h3><u>Formula to be used in the question:</u></h3>

Speed = Distance / Time

<h3><u>Distance for the first 2 hours:</u></h3>

= 130 km

<h3><u>Distance for the next 3 hours:</u></h3>

Speed = 85 km/h

Time = 3 hours

So,

Distance = Speed × Time

Distance = 85 × 3

Distance = 255 km

So,

<h3><u>Total distance from home to destination:</u></h3>

= 130 + 255

= 385 km

<h3><u>Speed on the return journey:</u></h3>

Total distance = 385 km

Time = 5 hours

Speed = Distance / Time

Speed = 385 / 5

Speed = 77 km/hr

Evaluate the expression

nadezda [96]

Answer:

Step-by-step explanation:

We are given the expression:

$\frac{-8(13-37)}{6}$

and asked to evaluate the expression.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve inside the parentheses first. Subtract 37 from 13.

⇒ 13-37= -24

$\frac{-8(-24 )}{6}$

Next, multiply -8 and -24.

⇒ -8*-24= 192

$\frac{192}{6}$

Finally. divide 192 by 6.

⇒ 192/6 = 32

$32$

When evaluated, the expression -8(13-37)/6 is equal to 32.
