Answer:

**Answer:15**

8-(-7)=8+ 7=15 BECAUSE -(-7) = +7

**Step-by-step explanation:**

BECAUSE -(-7) = +7 SO THE PROBLEM CHANGES TO 8+7=15

P=10 HAS NOTHING TO DO WITH THE FORMULA. K-M=?

Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 230 yards on average. A random sample of 177 golfers show that their mean driving distance is 230.7 yards, with a standard deviation of 41.8.1. Set up the null and alternative hypotheses to test for the designers belief.a. H0 : µ ≥ 230 versus Ha : µ < 230b. H0 : µ = 230.7 versus Ha : µ ≠ 230.7c. H0 : µ ≥ 230.7 versus Ha : µ < 230.7d. H0 : µ ≤ 230.7 versus Ha : µ > 230.7e. H0 : µ ≤ 230 versus Ha : µ > 2302. Find the value of the standardized test statistic.a. 0.125b. -0.125c. 0.223d. -0.7e. 0.73. Find the P-value for the above mentioned test.a. 0.8237b. 0.0228c. 0.5871d. 0.4118e. 0.0871

What is the number if 2 is 12.5% of a number?PLS HELP ME!!!

Caroline needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 2.75 hours and charged her $114 for parts. The total was $320.25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

a

11/2

b

13/2

c

5

d

7

Answer:

D. 7

Step-by-step explanation:

(8+4) = 2(x-1) multiply (x-1) by 2

(8+4) = 2x-2 add 8 and 4

12 = 2x-2 add 2 on both sides

14 = 2x divide both sides by 2

7 = x

Answer is D

12 = 2x - 2

14 = 2x

14/2 = x

7 = x

12 = 2x - 2

14 = 2x

14/2 = x

7 = x

Has condition Does not have condition totals

Test positive

Test negative

Totals

What is the probability (as a percentage) that a person has the condition if he or she tests positive? (Round your answer to one decimal place.)

**Solution:**

Population in the city= 10,000

As genetic condition affects 8% of the population.

8 % of 10,000

As, it is also given that, there is an error rate of 1% for condition (i.e., 1% false negatives and 1% false positives).

**So, 1% false negatives means out of 800 tested who are found affected , means there are chances that 1% who was found affected are not affected at all.**

So, 1% of 800

**Also, 1% false positives means out of 10,000 tested,[10,000-800= 9200] who are found not affected , means there are chances that 1% who was found not affected can be affected also.**

So, 1% of 9200

1. Has condition Does not have condition totals = 800

2. Test positive =92

3. Test negative =8

4. Total =800 +92 +8=900

5. Probability (as a percentage) that a person has the condition if he or she tests positive= As 8% are found positive among 10,000 means 9200 are not found affected.But there are chances that out of 9200 , 1% may be affected

**that is Probability equal to 0.01 or 1%.**

**Answer:**

(a) 3178

(b) 14231

(c) 33152

**Step-by-step explanation:**

**Given**

**Solving (a): Year = 1998**

**1998 means t = 8 i.e. 1998 - 1990**

**So:**

** --- approximated**

**Solving (b): Year = 2003**

**2003 means t = 13 i.e. 2003 - 1990**

**So:**

** --- approximated**

**Solving (c): Year = 2006**

**2006 means t = 16 i.e. 2006 - 1990**

**So:**

** --- approximated**

B. (30, 55)

C. (60, -40)

D. (40, 60)

I believe it is C. (60, -40)

28 copies !!!!!!! In 42 second

**Answer:**

It should be 28 copies

**Step-by-step explanation:**

If you divide 42 by 18 it gives you 2.33333333

If you multiply 12 by 2.33333333 it gives you 28

**Answer:**

**b. Must be between 1.3 and 2.2**

**Step-by-step explanation:**

**The formula for calculating median is :**

**When n(number of observations in data) is odd =****When n is even =**

Since in our data n is even so we use the formula for calculating median

=

First arranging data in ascending order we get :

** 1.2, 1.3, 1.9, 2.2, 2.4 and since we know nothing about our sixth value x so we assume that it may take any position in our data.**

Now there may be cases for which position is x on ;

- If x is the first obs in our data then our median = =

= 1.6

- If x is between 1.2 and 1.3 then also median will be 1.6 .

- If x is between 1.3 and 1.9 then median will be somewhere between 1.3 and 1.9 .
- If x is between 1.9 and 2.2 then median will be somewhere between 1.9 and 2.2 .

- And If x is between 2.2 and 2.4 or after 2.4 then median =

= = 2.05 .

**So from all these observations we conclude that without knowing what x median of data must be between 1.3 and 2.2 .**

The **median **of a set of bids can be found by arranging them in numerical order and selecting the middle value.

The median is the middle **value **of a set of data arranged in numerical order. In this case, we have a set of six bids: 2.2, 1.3, 1.9, 1.2, 2.4, and x (blurred number). To find the median, we first need to arrange the bids in **numerical **order:

- 1.2
- 1.3
- 1.9
- 2.2
- 2.4
- x

Since there are six bids, the middle value will be the fourth number in the ordered list. Therefore, the median is 2.2.
