Answer:

Lets take the hypothesis

<em>zα/2 </em>

<em>- zα/2 </em>

Step-by-step explanation:

<em>α/2 = 0.10/2 = 0.05 </em>

<em>z(0.05) = 3.92 </em>

<em>-z(0.05) = -3.92 </em>

Julio caught 3 fish weighing a total of 23 1/2 pounds. One fish weighed 9 5/8 pounds and another weighed 6 1/4 pounds. How much
Airida [17]
So we need to know what 23 1/2 + 9 5/8 + 6 1/4 is.
first, we need to make them into equivalent fraction. 
so...
23 1/2 can be 23 4/8
9 5/8 and
6 1/4 can be 6 2/8
let's add the whole numbers.
23 + 9 + 6 = 38
4/8 + 5/8 + 2/8 = 11/8 = 1 3/8
so 38 + 1 3/8 is 39 3/8
the answer is 39 3/8 pounds

How do I find the x and the y
mart [117]

Answer:

x = 22

y = 35

Step-by-step explanation:

Because its an isosceles triangle, you know the base angles are equal so:

3x - 11 = 2x + 11

Solving:

subtract 2x from both sides

x-11=11

add 11 to both sides

x = 22

Next, find the angle measures of the two base angles:

3*22-11\\66-11\\55

To find y, you know that the interior angles of the whole triangle add up to 180, so you have

55 + 55 + 2y = 180

solving,

110 + 2y = 180

subtract 110 from both sides

2y = 70

divide both sides by 2

y = 35

Which numbers are factors of 29? Select all that apply.<br><br> 5<br> 9<br> 1<br> 21
Tamiku [17]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Factors are values that the number can be divided by to produce an integer (whole number)

Simply test them out:

29/5 = 5.8

29/9 = 3.2

29/1 = 29

29/21 = 1.38....

As per the statement above, the only factor of 29 from this line is 1.
