Claim: the standard deviation of pulse rates of adult males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic
Answers
Answer:
182.58842
Step-by-step explanation:
Given that:
Sample size (n) = 171
Population standard deviation σ = 11
Sample standard deviation s = 11.4
males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic
The test statistic :
X² = ((n - 1) / σ²) * s²
X² = ((171 - 1) / 11²) * 11.4²
X² = ((170) / 121) * 129.96
X² = 1.4049586 * 129.96
X² = 182.58842

Which equation below would be perpendicular to the line x=5
a. y = 1/5x
b. y = 3
c. x =2
d. y = -5x
Answers
Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!

At a basketball game, 95% of people attending were supporting the home team, while
5% were supporting the visiting team. If 532 people attending the game supported
the home team, what was the total number of people attending the game?
Help
Answers
Answer:
3800
Step-by-step explanation:
Answer:
560 total people attending the game.
Step-by-step explanation:
95 : 100 = 532 : x
(95%) 95 is to 100 = 532 (the # of people supporting the home team) is to x (the total number of people attending the game)
x = (532*100) /95
x = 560 total people attending the game.
5% of 560 = 28 visitor team Supporters.
Which equation demonstrates the distributive property? A = 7(1+6)=7(6+1) B = (7x1) x 6 = 7(1x6) C = (7x1) x 6 = 7(6x1) D = 7(1+6) = (7x1) + (7x6) HELP END OF SEMSSTER
Answers
Answer:
D. 7(1+6) = (7x1) + (7x6)Step-by-step explanation:
Let A, B and C be any integer or function. According to distributive property;
A(B+C) = AB + AC
From the expression, you can see that A is distributed over B and C during the expansion.
Based on this same concept, the equation that demonstrates the distributive property from the given options is 7(1+6) = (7x1) + (7x6)
From the equation, you can see that 7 is distributed over 1 and 6 to give 7(1) + 7(6).
The remaining options demonstrates the commutative property.

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The y-intercept is of 2, as when x = 0, y = 2.The slope is of 1, as when x changes by 2, y also changes by 2, hence m = 2/2 = 1.Thus the function is given by:
y = x + 2.
Which means that the initial amount is of $2, and increases by $1 for each unit of time, hence the correct option is:
Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

What is the expression for the total cost of the tickets for William’s family and what was the total cost?
Answers
Answer:
43$
Step-by-step explanation: Three tickets total.
2 tickets cost 13$ =26
1 ticket 17 = 43 total
Hope this helped! God Bless!!
The total cost of the tickets for William’s family with 1 adult and 2 children is $43.

Price for a child = $13
What will be the total number of tickets be bought?The total number of tickets to be bought will be 3 i.e. William, His Granddad, and William's younger brother i.e. 1 adult ticket and 2 children tickets.
Total price = price of 1 adult ticket + price for 2 children's ticket
Total price =17+2*13
Total price =17+26
Total price =$43
Therefore, the total cost of the tickets for William’s family is $43.
