Serga [27]3 years ago

Answer:

104 units

Step-by-step explanation:

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.

AB=\\BC=20\\CD=30\\AD=

A'B'=22\\B'C'=\\C'D'=\\A'D'=32

Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:

AB=22\\BC=20\\CD=30\\AD=32

A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32

See? Notice how the values are the same! To find the perimeter (P) of a quadrilateral, we have to add each side length:

P=22+20+30+32

Solve:

P=104

denis23 [38]

Answer:

We accept H₀ , we do not have enought evidence for rejecting H₀

Step-by-step explanation:

Normal Distribution

sample size   n  =   60

standard deviation     σ  =  15

1.Hypothesis Test : Is a one tailed-test on the right

H₀      null hypothesis             μ₀  = 50

Hₐ    alternative hypothesis   μ₀  > 50

2.-We will do the test for  a significance level   α =  0,01 tht means for a 99% interval of confidence

then z(c)  =  2.32

3.- We compute z(s)  

z(s)  =  [ ( μ - μ₀ ) /( σ/√n )       ⇒  z(s)  =  (  2 * √60 ) / 15

z(s)  = 15.49/15                        ⇒   z(s)  = 1.033

4.- We compare values of  z(c)   and z(s)

z(s)  <  z(c)      1.033 < 2.32

z(s) is in the acceptance region so we accept H₀ , we do not have enough evidence for rejecting H₀

Solve for x. 2 1/2x−3/4(2x+5)=3/8
RUDIKE [14]
2 \frac{1}{2}x- \frac{3}{4}(2x+5)= \frac{3}{8}
2 \frac{1}{2}x- \frac{6}{4}x- \frac{15}{4}= \frac{3}{8}
( 2\frac{1}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}
( \frac{5}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}
( \frac{10}{4}- \frac{6}{4})x= \frac{3}{8}+ \frac{30}{8}
\frac{4}{4}x= \frac{33}{8}
x= \frac{33}{8}=4 \frac{1}{8}
