Can someone help me with the top 1-3. Using similar figures subject

Mathematics
1 answer:
katen-ka-za [31]3 years ago
7 0
Answer: <M corresponds to <J
               <L corresponds to <O
               JL corresponds to MO 

To find the corresponding angles:
1. Look at the figures. 
<M is to <J, <N is to <K, and <O is to <L.

2. Look at the similarity statement. 
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.

Apply these two methods to find the corresponding sides.

If you want to construct a 90% confidence interval, what critical value (z*) should you use? Group of answer choices 2.576 1.960
Rom4ik [11]

Answer:

For this case we know that the confidence level is 90% so then the significance level is \alpha=1-0.9 =0.1 and \alpha/2 =0.05. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:

z_{\alpha/2}= \pm 1.645

And the best option would be:

1.645

Step-by-step explanation:

We assume that the parameter of interest is \theta and we can assume that the distribution for this parameter is normally distributed so then the confidence interval assuming a two sided interval is given by:

\hat \theta \pm z_{\alpha/2} SE

Where \hat \theta represent the estimator for the parameter, SE the standard error and z_{\alpha/2} the critical value.

For this case we know that the confidence level is 90% so then the significance level is \alpha=1-0.9 =0.1 and \alpha/2 =0.05. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:

z_{\alpha/2}= \pm 1.645

And the best option would be:

1.645

I NEED HELP PLEASE, THANKSSS! :)
HACTEHA [7]

Answer: A) max at (14, 6) = 64,   min at (0,0) = 0

<u>Step-by-step explanation:</u>

Graph the lines at look for the points of intersection.

Input those points into the Constraint function (2x + 6y) and look for the maximum value and minimum value.

Points of Intersection: (0, 0), (17, 0), (0, 10), (14, 6)

Point     Constraint 2x + 6y

(0, 0):                    2(0) + 6(0) = 0              Minimum

(17, 0):                    2(17) + 6(0) = 34

(0, 10):                    2(0) + 6(10) = 60

(14, 6):                    2(14) + 6(6) = 64           Maximum

The sale tax in a certain state is 5 1/2%. What would be the tax on an item that costs $535.00
nexus9112 [7]

Answer:

$29.43

Step-by-step explanation:

5 1/2 % or 5.5% is 0.055 as a decimal.  Multiply 535 by 0.055 to find what 5.5% of 535 is...

0.055(535) = 29.425

Since we're working with dollars, round to the nearest hundredth, which is

$29.43
