Answer:
P=0.954 or 95.4%
Step-by-step explanation:
Using the formula for the standardized normal distribution to find Z:

Where μ is the mean (μ=20) and σ is the standard deviation (σ=2.6).


In the table of the normal distribution, we can look for positive values z, and these values are going to represent the area under the curve between z=0 and the values searched. the negatives values are found by symmetry (with the corresponding positive value but remember this area is under the left side of the curve). To find a value in the table, find the units in the first column and the follow over the same row till you find the decimals required.


represents the probability of length being between 14.8 and 20 (the mean) and
represents the probability of length being between 20 and 25.2, The requested probability is the sum of these two.

Step-by-step explanation:
It isn't clear what is supposed to go in the various blanks. We have elected to identify the corresponding congruent parts, and name the congruent triangles. The postulate supporting the conclusion is also shown.
In most cases, corresponding parts are marked congruent. The exception is the vertical angles in figure 22.

namely how many times does ¼ go into 2, well that'd be 2 ÷ ¼,

<u>Value of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>3</u><u>0</u><u>°</u>
Answer:
Solution given:
x°+(5x)°=180°[being straight line which sum of angle is 180°]
adding like terms
(6x)°=180°
dividing both side by 6
(6x)°/6=180°/6
x=30°
