Here are 10 test scores: 30, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 74.

creativ13 [48]

We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).

79-74 = 5. So the mean has increased by 5 points. (C)

I need help. What are the two numbers on the middle

Rina8888 [55]

Answer:

Miles: 35; Gallons: 1

Step-by-step explanation:

The number of gallons can be any number of your choosing that is less than 12, which is the capacity of the tank. For the purpose here, 1 is a convenient number. To find the corresponding number of miles (m), you need to solve the proportion ...

420/12 = m/1

35 = m

(miles, gallons) = (35, 1) . . . a suitable choice for the table values

<em>Additional comment</em>

If your sense of symmetry is offended by choosing 1 for Gallons, you can choose 10, a number halfway between 12 and 8. In that case, your proportion is ...

420/12 = m/10 ⇒ m = 350

Then, your entry would be ...

(miles, gallons) = (350, 10)

Emma tossed a six-sided die two times and recorded the sum of the two numbers. How many different sums are possible for her to r

guajiro [1.7K]

Answer:

Step-by-step explanation:

6 times 6 is 36

Think about this you row a 1 first the possible result of the next row is 1,2,3,4,5,or 6 and that is 6 possible sums.

Which is 2, 3, 4, 5, 6, and 7

Next she rows 2 with again 6 possible results

Which is 3, 4, 5, 6, 7,and 8

Then she rows a 3, 4, 5,and 6

with the possible results

4, 5, 6, 7, 8, 9

5, 6, 7, 8, 9, 10

6, 7, 8, 9, 10, 11

7, 8, 9, 10, 11, 12

They asked for different sums so out of the results the different sums is

2, 3, 4, 5, 6, 7, 8, 9, 10, 11,and 12

Please help.. 10 points

Answer:

z = 55.15432893

x = 59.61543424

y = 22.5166605

Step-by-step explanation:

To find length "z" you will have to use SOHCAHTOA.

Labelling the triangle will show us that the side marked "z" is the hyp and the side marked 39 is the opp.

sin 45 = $\frac{39}{z}$

z sin 45 = 39

z = $\frac{39}{sin45}$

z = 55.15432893

Using Pythagoras' theorem, you can find that the adj = 39

In the other triangles POV, the adj is actually the opp.

Therefore, use tangent to find y.

tan 60 = $\frac{39}{adj}$

y tan 60 = 39

y = $\frac{39}{tan60}$

y = 22.5166605

Use Pythagoras's Theorem to find x.

$23^{2} + 55^{2} = x^{2}\\\sqrt{23^{2} + 55^{2}} = x\\59.61543424=x$
