(a) and (b) looks correct

(c) Here's how my table looks like:

15    -18      324
27    -6       36
28    -5       25
34     1         1
42     9        81
52     19      361
           SUM 828

(d) Take the sum of 828 and divide it by 6 to get 138.  Now take the square root of 138 to get the standard deviation:

sqrt(138) ≈ 11.75

Simplify and determine the coefficient of (-2/5x)(5y)(-2x).
Juli2301 [7.4K]
Solution/Answer : 4

Solution: the first you do is multiply the last two parentheses to get -10xy


Now we are left with ( -2/5x)(-10xy)
Then we multiply that out into
(-2*-10)/5*x^2y = 20/5x^2y =
4x^2y

The coefficient in this case would be four. (In case you were confused about what a coefficient actually is, it’s the number you multiply a variable by)

Hopes this helps :)

Can someone please help me
Ainat [17]

Answer:

20

Step-by-step explanation:

If the two triangles are similar, then corresponding sides must share a constant ratio. This means that:

\dfrac{10}{6}=\dfrac{25}{15}=\dfrac{x}{12}

Let's use the second ratio:

\dfrac{25}{15}=\dfrac{x}{12}

Multiply both sides by 12:

\dfrac{25\cdot 12}{15}=x \\\\x=20

Hope this helps!

Find the area and perimeter of parallelogram.
Aleonysh [2.5K]

Answer:

Area: 40 cm Perimeter: 30 cm

Step-by-step explanation:

When finding the area of a parallelogram, you use the inside length (in this case, 5cm) and the base (8cm). With perimeter, you use the base and the length (6cm).

8*5=40

8+8+6+6=30
