Answer:
About 12 prints in 11×14
Step-by-step explanation:
The area of the 4×8 print is 32 in².
60 × 32= 1960
Divide by the area of an 11×14, 154 in²
1960/154 ≈ 12.47
There is enough for a little more than 12, but not enough for 13 prints.

2. ABCD is a square and P, Q are the midpoints of BC,CD respectively. If AP = a
and AQ = b. find in terms of a and b the directed line segments (i) AB (ii) AD
(iii) BD and (iv) AC.
Answer:
The answer is below
Step-by-step explanation:
A square is a quadrilateral (four sides and angles). All the sides and angles of a square are equal. Each angle of a square is 90° and the diagonals are equal.
In square ABCD:
AB = BC = CD = AC (all the sides of a square are equal)
Given that P is the midpoint of BC and Q is the midpoint of CD. AP = a and AQ = b.
a) Triangle APB is a right angled triangle:
BC = AB (all sides of a triangle are equal)
PB = 1/2 (BC) = 1/2(AB) = 0.5AB
Using Pythagoras theorem:
AB² + PB² = AP²
substituting:
AB² + (0.5AB)² = a²
AB² + 0.25AB² = a²
1.25AB² = a²
AB² = 0.8a²
AB = a√0.8
b) Triangle AQD is a right angled triangle:
AD = DC (all sides of a triangle are equal)
DQ = 1/2 (DC) = 1/2(AD) = 0.5AD
Using Pythagoras theorem:
AD² + DQ² = AQ²
substituting:
AD² + (0.5AD)² = b²
AD² + 0.25AD² = b²
1.25AD² = b²
AD² = 0.8b²
AD = b√0.8
c) In right triangle ADB, Using Pythagoras theorem:
AB² + AD² = BD²
But AB = AD
Substituting:
0.8a² + 0.8b² = BD²
BD = √(0.8a² + 0.8b²)
But AD = AB, hence 0.8a² = 0.8b²
BD = √(1.6a²)
BD = a√1.6
D) AC = AD (diagonals of a square are equal)
AC = √(0.8a² + 0.8b²)
AC = √(1.6b²) = b√1.6

Answer:
(b) 540 boxes
Step-by-step explanation:
The 28 foot depth of the trailer will accommodate 18 boxes (leaving 1 ft unfilled).
The 8 1/2 foot width of the trailer will accommodate 5 boxes (leaving 1 ft unfilled).
The 9 1/6 foot height of the trailer will accommodate 6 boxes (leaving 1/6 ft unfilled).
The collection of boxes filling the trailer is 18 deep, 5 wide, and 6 high, for a total of ...
18 × 5 × 6 = 540 boxes
_____
In each case, the number of boxes that will fit is the dimension divided by the dimension of the box. The result is the integer part of the quotient. For example, ...
(28 ft)/(3/2 ft/box) = 56/3 box = 18 2/3 box . . . 18 boxes will fit

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X
represent the number of 1s that are spun. What are the mean and standard deviation of X?
O Wx = 1, 0x = 1.29
O x = 2,04 = 1.29
OH, = 2,0x = 1.67
O Mx = 10,0x = 2.78
Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
Step(i):-
Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6
Given that the probability of labelled '1'
[tex]p = \frac{1}{6}[/tex] =0.16
q = 1-p = 1- 0.16 = 0.84
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ = [tex]12 (\frac{1}{6} ) = 2[/tex]
The mean of the binomial distribution = 2
Step(ii):-
The standard deviation of X
σ [tex]= \sqrt{npq}[/tex]
σ = [tex]\sqrt{12(0.16)(0.84}[/tex]
σ = [tex]1.269[/tex]
The standard deviation of the binomial distribution
σ = [tex]1.269[/tex]

A helicopter descended 145 m to observe the density of the population during the Centennial celebration
at the Luneta. It leveled off 230 m. what is the original altitude?
Answer:
Original altitude = 375 m
Step-by-step explanation:
Given:
Current height of helicopter = 145 m
New leveled off = 230 m
Find:
Original altitude
Computation:
Original altitude = Current height of helicopter + New leveled off
Original altitude = 145 m + 230 m
Original altitude = 375 m
J.D. power and Associates calculates and publishes various statistics concerning car quality. The dependability score measures problems experienced during the past 12 months by original owners of three-year-old vehicles (those that were introduced for the 2017 model year). For these models of cars, Ford had 1.27 problems per car and Toyota had 1.12 problems per car. (Data extracted from 2013 U.S. Vehicle Dependability Study,J.D. Power and Associates, February 13, 2013, Let X be equal to the number of problems with a three -year -old Ford.
a. What assumptions must be made in order for X to be distributed as a Poisson random variable? Are these assumptions reasonable? Making the assumptions as in (a), if you purchased a Ford in the 2010 model year, what is the probability that in the past 12 months, the car had
b. zero problems?
c. two or fewer problems?
d. Give an operational definition for problem. Why is the operational definition important in interpreting the initial quality score?
Answer:
0.281 ; 0.864
Step-by-step explanation:
1.)
p decreases as n increases (n increases, p--> 0)
λ ≥ 0
P(x = x) = (e^-λ * λ^x) ÷ x!
λ for Ford = 1.27
B) zero problems :
P(x = 0) :
(e^-1.27 * 1.27^0) ÷ 0! = 0.281
P(x = 0) = 0.281
Two or fewer problems :
P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)
P(x ≤ 2) = 0.281 + 0.357 + 0.226
P(x ≤ 2) = 0.864
D.) It allows for early detection and thus adequate curtailment of the problem at an a stage in which it seems easier to curb.

Answer:
h(x) = (x + 4)^2 - 2
Step-by-step explanation:
Start with the red graph: f(x) = x^2
First we move the entire graph 4 units to the left. The resultant function is g(x) = (x + 4)^2.
Next, we move this latest graph 2 units down. The resultant function (and answer to this question) is h(x) = (x + 4)^2 - 2

8. A drug and placebo were tested on 23 people each to study their effect on cholesterol. The mean cholesterol levels with the people on the new drug are 195 and SD of 35. The values for placebo sample are 245 and SD of 31. Using 5% level of significance, does the drug have effect on lowering the cholesterol.
Answer:
The drug have effect on lowering the cholesterol.
Step-by-step explanation:
H₀ : μ₁ - μ₂ = 0
⇒ H₀ : μ₁ = μ₂
H₁ : μ₁ - μ₂ < 0
⇒H₁ : μ₁ < μ₂
Now,
given , n₁ = 23 , n₂ = 23
∴ Degree of freedom = v = n₁ + n₂ - 2
= 23 + 23 - 2 = 44
⇒v = 44
Now,
Given, level of significance = 5% = 0.05
For the given significance level, critical time t = 1.68
As
Decision rule states that'if t < 1.68 , reject H₀
Now,
For Drug:
mean = m₁ = 195
SD = d₁ = 35
People = n₁ = 23
For placebo :
mean = m₂ = 245
SD = d₂ = 31
People = n₂ = 23
Now,
Variance = [tex]\frac{(23-1)35^{2} + (23-1)31^{2} }{23 + 23 - 2}[/tex] = 1093
Standard Deviation, S = 33.06
Point estimate = m₁ - m₂ = 195 - 245 = -50
Standard deviation error = S×([tex]\frac{1}{n_{1} } + \frac{1}{n_{2} }[/tex] ) = 9.75
Now,
Test statistics = [tex]-\frac{50}{\sqrt{9.75} } = -5.13[/tex]
⇒ t < 6.13
⇒Reject H₀
⇒The drug have effect on lowering the cholesterol.
Montrey recently paid off his simple interest loan. If he borrowed $6,500 for 5 years at 7%, what was the total amount he had to pay back?
9514 1404 393
Answer:
$8,775
Step-by-step explanation:
The amount due is given by the formula ...
A = P(1 +rt)
where P is the principal amount, r is the annual rate, and t is the number of years.
A = $6,500(1 +0.07×5) = $6,500(1.35) = $8,775
Montrey had to pay back $8,775.
Two joggers set out at the same time from their homes 24 miles apart. They agree to meet at a point
somewhere in between in an hour and a half. If the rate of one is 6 mph faster than the rate of other,
find the rate of each.
9514 1404 393
Answer:
5 mph, 11 mph
Step-by-step explanation:
Together, they cover 24 miles in 1.5 hours, so their total rate of speed is ...
(24 mi)/(1.5 h) = 16 mi/h
If s is the rate of the slower jogger, then s+6 is the rate of the faster one. Their total speed is ...
s + (s+6) = 16
2s = 10 . . . . . . . subtract 6
s = 5 . . . . . . . . . divide by 2
s+6 = 11
The rates of the joggers are 5 mph and 11 mph.

A survey was conducted to find the frequency with which people go to the movies. A group of 120 people in a mall were asked about how often they go out for a movie and It was found that 36 people go to movies at least once in a month. Which of these is an example of descriptive statistics
Answer:
30% of the people surveyed in the mall go to movies at least once in a month
Step-by-step explanation:
A descriptive statistic would refer to a summary where it explain in quantitative way from the information collected also it it is used to analyze it. The parameter and descriptive statistics would be the percentage for the surveyed people that goes to the mall for watching out the movies at least for one time in a month
Here 30% come from
= 36 ÷ 120
= 30%
For the sequence tn=n^2-2n,find the third term
Answer:
t₃ = 3
Step-by-step explanation:
To find the third term substitute n = 3 into the formula, that is
t₃ = 3² - 2(3) = 9 - 6 = 3
Answer:
tn=n^2-2n
n =3
t3 = 3^2 -2(3)
