A sample of 23 women athletes, aged 20 was taken. The systolic blood pressure of these women had an average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
Answer:
Step-by-step explanation:
average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
From the above question
Number of samples = 23 , less than 30,
Hence, we find confidence interval using t score
Confidence Interval using t score =
Mean + t score × standard deviation/√n
Step 1
We find the degree of freedom
= N - 1
= 23 - 1
= 22
Elena donates some money to charity whenever she earns money as a babysitter. What percent of her income does She donate?
Answer:
10%
Step-by-step explanation:
The question is incomplete due to missing data

The spinner above is used in a game. What is the theoretical probability of the given event with one spin? P (5)
Answer:
1 /8
Step-by-step explanation:
Given that :
Number of sections on spinner = (1,2,3,4,5,6,7,8) = 8
Number of 5's = 1
Recall :
Probability of event A = number required outcome / Total possible outcomes
P(5) = 1/8

What is the slope of the line that passes through the points (26, 7) and (-39, 12)?
Answer:
Step-by-step explanation:
point P1 = (26,7) in the form (x1,y1)
point P2 = (-39,12) in the form (x2,y2)
slope , m , of a line is:
m = (y2 - y1) / (x2 - x1)
m = (12-7) / ( -39-26)
m = 5 / -65
m = - 1 / 13
m = - [tex]\frac{1}{13}[/tex]
Consider the plane T. and three collinear (but not coplanar) points P, Q, and W.
Can either P, Q, or Wbe a point on the plane T?
A Yes, because if points are collinear, they must all fall on the same plane and be coplanar.
B Yes, because even if points are collinear, one of the points may fall on a plane while the others do not.
C No, because if points are collinear, they must all fall on the same plane and be coplanar.
D No, because even if points are collinear, one of the points may fall on a plane while the others do not.
Answer:
B Yes, because even if points are collinear, one of the points may fall on a plane while the others do not.

Which of the following statements have the same result? Explain each step in solving each one.
I. f(2) when f(x) = 3x + 4
II. f−1(4) when f(x) = 3x - 4 over 5
III. 3y − 6 = y + 10
Answer:
1). 10 2). 8/5 3). 8
Step-by-step explanation:
I. f(2) = 3(2) + 4
= 6 + 4
= 10
II. f(4) = 3(4) - 4/5
= 12 - 4/5
= 8/5
III). 3y - 6 = y + 10
2y - 6 = 10
2y = 16
y = 8

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they arrive?
Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
1 hr 55 minutes
90 minutes
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
1 hr 55 minutes
10hrs 30 minutes
Therefore, They arrived at 10:30

Sophia's retirement party costs $2 ,plus an additional $3 for each guest she invites.What is the maximum number of guests there can be if Sophia can afford to spend a total of $35 on her retirement party?
Answer:
11
Step-by-step explanation:
Sophia can only have 11 guest max at the retirement party if she can only afford to spend $35.
Given: $2 cost of party
Needed: How many guests
$3 per guests multiplied by 11 guests is $33
add that to the original (given) cost of party the total is
$35
3 times 11=33
33+2=35

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.
The investment worth after 5 years to the nearest dollar will be $3601.
What is compound interest?We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.
The worth of investment after 5 years is calculated as,
A = $3,069 x (1 + 0.0325)⁵
A = $3,069 x 1.0325⁵
A = $3,069 x 1.1734
A = $3601
The investment worth after 5 years to the nearest dollar will be $3601.

5. Given AADL AAKM with AD = 14, DK = 21, and
AL= 15. What is the measure of LM?
Answer:
22.5
Step-by-step explanation:
first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.
as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.
that means they have the same angles.
and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.
that means, if one side changes by a factor f, then both other sides must change by the same factor.
so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.
the original AD = 14.
AK = AD + DK = 14 + 21 = 35
the change factor f is then AK/AD = 35/14 = 5/2
in other words AD grew by a factor of 5/2.
AM is then created by applying the same factor to AL.
=> AM = 15 * 5 / 2 = 75 / 2 = 37.5
=> LM = AM - AL = 37.5 - 15 = 22.5

The class must raise at least 100$ to go on the field trip. They have collected 20$. Write an inequality to represent the amount of money (m) the class still needs to raise.
Answer: 20x < 100
subtract 20 from both sides
20 - 20 = 0
100 - 20 = 80
x < 80
