Answer:

<em>No solutions</em>

Step-by-step explanation:

4(2r + 3) = 15r - 11 + 1 - 7r

Distribute:

8r + 12 = 15r - 11 + 1 - 7r

Combine like terms:

8r + 12 = 8r - 10

Same to both sides:

0r = -22

<em>No solutions</em>

Find the area of the shape shown below. I NEED HELP NOWWWWWW

Varvara68 [4.7K]

Answer:

<h2> 12.5 units ${}^{2}$ </h2>

Step-by-step explanation:

Given figure : Trapezoid

Base sides,

a = 2.5

b = 7.5

Height ( h ) = 2.5

Now, finding the area:

$\frac{1}{2} (a + b) \times h$

Plug the values

$= \frac{1}{2 } \times (2.5 + 7.5) \times 2.5$

Calculate the sum

$= \frac{1}{2} \times 10 \times 2.5$

Reduce the numbers with G.C.F 2

$= 5 \times 2.5$

Calculate the product

$12.5 \: \: {units}^{2}$

Hope this helps...

Best regards!

A simple random sample of 5 months of sales data provided the following information: Month: 1 2 3 4 5 Units Sold: 94 105 85 94 9

11111nata11111 [884]

Answer:

a) x = 94 units/month

b) s = 51.50 units/month

Step-by-step explanation:

The adequate point estimation of the population mean and standard deviation are the sample mean and sample standard deviation.

a) Point estimation of the population (sample mean)

$M=\dfrac{1}{n}\sum_{i=1}^n\,x_i\\\\\\M=\dfrac{1}{5}(94+105+85+94+92)\\\\\\M=\dfrac{470}{5}\\\\\\M=94\\\\\\$

b) Point estimation of the population standard deviation (sample standard deviation)

$s=\dfrac{1}{n-1}\sum_{i=1}^n\,(x_i-M)^2\\\\\\s=\dfrac{1}{4}((94-94)^2+(105-94)^2+(85-94)^2+(94-94)^2+(92-94)^2)\\\\\\s=\dfrac{206}{4}\\\\\\s=51.50\\\\\\$
