I believe the answer is D) 12\/-2  (I don't know how to write it with a normal keyboard. lol) Because sides A and B are both 6\/-2.  A^2 + B^2 = C^2

\sin(\theta) = \dfrac{\text{opp}}{\text{hyp}}

\sin(45) =  \dfrac{6 \sqrt{2} }{x}

x=  \dfrac{6 \sqrt{2} }{\sin(45)}

x= 12

Find the area of the shape shown below.
miskamm [114]

Answer:

28 units^2

Step-by-step explanation:

1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).

2. Next, we should know the area formulas of the square and trapezoid.

  • Square: s^2, where s = side
  • \frac{a+b}{2}h, where a and b = top and bottom and h = height

3. Solving Area of Square and Trapezoid

  • 4^2 = 4 * 4 = 16. Area of square is 16
  • \frac{4+2}{2}*4 = \frac{6}{2} * 4 = 3 * 4 = 12. Area of trapezoid is 12.
  • 16 + 12 = 28

Therefore, the area of the figure is 28 units^2.

A sequence is formed by adding 1 to each square number.
MrRa [10]

Answer:

32 nd term

Step-by-step explanation:

The formula for the sequence is

n² + 1 ( that is 1 added to each square number )

Equate to 1025 and solve for n

n² + 1 = 1025 ( subtract 1 from each side )

n² = 1024 ( take the square root of both sides )

n = \sqrt{1024} = 32

Batteries produced by a manufacturing company have had a life expectancy of 135 hours. Because of an improved production process
Nikolay [14]

Answer:  c. z = 1.35; Reject the null hypothesis

Step-by-step explanation:

Let \mu be the average life expectancy of its batteries.

As per given , we have

Null hypothesis : H_0 : \mu =135

Alternative hypothesis : H_a : \mu >135

Since H_a is right-tailed and population standard deviation is also known, so we perform right-tailed z-test.

Test statistic : \dfrac{\overlien{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

where, n= sample size

\overlien{x}= sample mean

\mu= Population mean

\sigma=population standard deviation

For n=42,\ \overline{x}=140\ \&\ \sigma=24, we have

z=\dfrac{140-135}{\dfrac{24}{\sqrt{42}}}=1.35015431217\approx1.35

Critical one-tailed test value for 0.10 significance level :

z_{0.1}=1.28

 Decision : Since critical z value (1.28) < test statistic (1.35), so we reject the null hypothesis .

[When critical value is less than the test statistic value , we reject the null hypothesis .]
