The score of golfers for a particular course follows a normal distribution that has a mean of 73 and a standard deviation of 3.

Artemon [7]

Answer:

P(X $\geq$ 74) = 0.3707

Step-by-step explanation:

We are given that the score of golfers for a particular course follows a normal distribution that has a mean of 73 and a standard deviation of 3.

Let X = Score of golfers

So, X ~ N( $\mu=73,\sigma^{2}=3^{2}$ )

The z score probability distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = population mean = 73

$\sigma$ = standard deviation = 3

So, the probability that the score of golfer is at least 74 is given by = P(X $\geq$ 74)

P(X $\geq$ 74) = P( $\frac{X-\mu}{\sigma}$ $\geq$ $\frac{74-73}{3}$ ) = P(Z $\geq$ 0.33) = 1 - P(Z < 0.33)

= 1 - 0.62930 = 0.3707

Therefore, the probability that the score of golfer is at least 74 is 0.3707 .

George wrote an integer. The opposite of George’s integer is -53. Which of these statements about George’s integer must be true?

vlabodo [156]

The George's integer must be true for option D)I and IV.

What is integer?

A full number (not a fraction) that can be positive, negative, or zero is called an integer . -5, 1, 5, 8, 97, and 3, 043 are some examples of integers. 1.43, 1 3/4, 3.14, and other numbers are examples of non-integer numbers. Integer, which means full or whole in Latin, is the root of the English term integer. A particular category of numbers called integers includes zero, positive numbers, and negative numbers. All whole numbers, both negative and positive, and 0 are considered integers.

Here the opposite of George integer is -53.

We know that opposite value of x is -x.

Then George integer is 53.

George integer must be true for The given options I. the integer is 53 and IV.The integer has absolute value of 53.

Therefore the correct option is D) I and IV.

To write the polynomial −x^3 + x^4 + x − x^2 in standard form, which term should go first?

Goshia [24]

Answer: OPTION D

Step-by-step explanation:

To express a polynomial in Standard form, you need to see the exponent of each term of the polynomial and then order the polynomial from highest exponent to lowest exponent.

Therefore, for the polynomial $-x^3 + x^4 + x - x^2$ , you can see that the term that thas the highest exponent is x⁴ (The quartic term).

Then, this polynomial written in Standard form is:

$x^4 - x^3 - x^2+x$

Therefore, the term that should go first is: the quartic term.

Determine whether the value given below is from a discrete or continuous data set. The volume of cola in a can is 11.5 oz. Nothi

AnnyKZ [126]

Volume will represent a continuous data set.

Why? <em>because you can have any measurement (1 oz, 0.1 oz, 0.001 oz, etc)</em>

A discrete data set is when you cannot have a "part" of the whole. An example would be if the data set is the number of people ... you can't have 1/2 of a person. Another example would be a product (tv, laptop, etc) ... you can't have a part of the product. you either have 1 or 2 or 3, etc.

Answer: Continuous
