Answer:
The probability that the average score of the 49 golfers exceeded 62 is 0.3897
Step-by-step explanation:
The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5
We are supposed to find he probability that the average score of the 49 golfers exceeded 62.
Formula : 
Refer the z table for p value
p value = 0.6103
P(x>62)=1-P(x<62)=1-0.6103=0.3897
Hence the probability that the average score of the 49 golfers exceeded 62 is 0.3897
To factor x²-2x-4, you are looking to answer three questions.
1) What pair of numbers multiplies to 4?
2) What pair of numbers multiplies to 1?
3) Do these pairs when multiplied together, add/subtract to the middle term?
To answer (1), our pairs are 2 and 2, 4 and 1. Since there's a negative with 4 at the end (from question one), the signs will be opposite.
To answer (2), only pair multiplies to 1 - 1 and 1. Let's try both pairs from 1.
(x-4)(x+1) The middle term here is -3x. Nope.
(x-1)(x+4). The middle term here is 3x. Nope.
(x-2)(x+2) The middle term is 0x (or no middle term). Nope.
So x²-2x-4 does not factor.
Answer:
The correct answer is option B
Answer:
The answer is 25064.
Step-by-step explanation:
<u>There is a mistake in the question so the correct is below:</u>
What is 6 tenths 20 thousandths 4 ones and 50 hundreds.
Now, to solve it:
So, we arrange it in sequence:
20 thousandths 50 hundreds 6 tenths and 4 ones.
Now,
20 thousandths = 20 <u>000</u>
50 hundreds = 50 <u>00</u>
6 tenths = 6 <u>0</u>
4 ones = 4
Thus, 20 thousandths 50 hundreds 6 tenths and 4 ones is :
20,000 + 5000 + 60 + 4.
= 25064.
Therefore, the answer is 25064.
