Answer:
the answer 9/64 hope it helps
Answer:
[tex]\frac{9}{64}[/tex]
Step-by-step explanation:
[tex]\frac{3}{4}[/tex] ÷ [tex]5\frac{1}{3}[/tex]
First translate [tex]5\frac{1}{3}[/tex] into an improper fraction.
[tex]5\frac{1}{3}[/tex] = [tex]\frac{16}{3}[/tex]
So that means: [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{16}{3}[/tex].
Now you have to switch [tex]\frac{16}{3}[/tex] to its reciprocal to multiply.
[tex]\frac{3}{4}[/tex] x[tex]\frac{3}{16}[/tex] = [tex]\frac{9}{64}[/tex]
Therefore, the answer is [tex]\frac{9}{64}[/tex].

what is 87,628 divided by 931 is Long divison
Answer:
94 remainder 114
Step-by-step explanation:
87,628 ÷ 931 = ?
87,628 is not divisible by 931. The closest number that is divisible by 931 is 87,514.
931 × 94 = 87,514
87,628 - 87,514 = 114
87,628 ÷ 931 = 94 remainder 114

c. b. Use the model to find the distance traveled after 2.5 days of travel.
Answer:
a. independent = number of days
dependent = number of miles
b. f(x)=340x
x = number of days
f(x) = number of miles
c. f(x)=850
850 miles
Step-by-step explanation:
a. the number of miles depends on number of days because more days equals more miles traveled.
b. Idk u need y or f(x) but just switch to one u need.
c. 340 × 2.5 = 850

An airline makes 200 reservations for a flight who holds 185 passengers. The probability that a passenger arrives for the flight is 0.9 and the passengers are assumed to be independent. Use the normal approximation of Binomial distribution to answer the following questions.
a. Approximate the probability that all the passengers who arrives can be seated.
b. Approximate the probability that there are empty seats.
c. Approximate the number of reservations that the airline should make so that the probability that everyone who arrives can be seated is 0.95.
Answer:
The answer is below
Step-by-step explanation:
given that:
n = sample size = 200, p = probability of a cancelled reservation = 1 - 0.9 = 0.1
The z score is given by:
[tex]z=\frac{x-mean}{standard\ deviation} =\frac{x-np}{\sqrt{np(1-p)} }[/tex]
a) The probability that all the passengers who arrives can be seated can only occur if atleast 15 or more passengers cancelled their reservations.
P(X ≥ 15) = 1 - P(X ≤ 14.5)
[tex]z=\frac{x-np}{\sqrt{np(1-p)} }=\frac{14.5-(200*0.1)}{\sqrt{(200*0.1)(1-0.1)} }=-1.3[/tex]
From the normal distribution table:
P(X ≥ 15) = 1 - P(X ≤ 14.5) = 1 - P(z < -1.3) = 1 - 0.0968 = 0.9
b) The probability that there are empty seat only occur if atleast 16 or more passengers cancelled their reservations.
P(X ≥ 16) = 1 - P(X ≤ 15.5)
[tex]z=\frac{x-np}{\sqrt{np(1-p)} }=\frac{15.5-(200*0.1)}{\sqrt{(200*0.1)(1-0.1)} }=-1.06[/tex]
From the normal distribution table:
P(X ≥ 16) = 1 - P(X ≤ 15.5) = 1 - P(z < -1.06) = 1 - 0.1446 = 0.8554
c)
[tex]0.95=P(X\geq n-185)=1-P(X\leq n-185)\\\\P(X\leq n-185)=1-0.95\\\\P(X\leq n-185)=0.05\\\\0.05=P(Z<\frac{n-185-0.1n}{\sqrt{0.9*0.1*n} } )\\\\0.05 \ correspond\ to \ a\ probability\ of\ -1.64\\\\-1.64=\frac{0.9n-185}{\sqrt{0.9*0.1*n} } \\\\n=198[/tex]

3 schools are participating in a donut fundraiser and shipments have been delivered each pallet has 10 cartons East curtain has 10 boxes each box has 10 donuts the shipment consist of five pallets six cartons for boxes and eight individually wrapped donuts how can the donuts be shared equally among five classes
Answer: Each class get 1121 donuts (3 donuts are still left).
Step-by-step explanation:
Given : 1 pallet has 10 cartons.
1 carton has 10 boxes.
1 box has 10 donuts.
So, 1 pallets has 10 x 10 x 10 =100 donuts
1 carton has 10 x 10 =100 donuts
In shipment,5 pallets, six cartons and eight individually wrapped donuts
= 5x 1000+6x 100+ 8
=5608
Total classes =5
Number of donuts 1 class get = 5608 ÷5 =[tex]1121\dfrac{3}{5}[/tex]
So each class get 1121 donuts (3 donuts are left).
find the quotient, then check your answer using multiplication

Which division problem does the diagram below best illustrate?
A diagram with 5 ovals containing 7 squares.
30 divided by 5 = 6
35 divided by 7 = 5
21 divided by 7 = 3
40 divided by 5 = 8
Answer:
B
The division which correctly illustrates a diagram with 5 ovals containing 7 squares is: 35 divided by 7 = 5
What is division?"It is the process of breaking a number up into equal parts."
What is equation?"It is a statement which consists of equal symbol between two algebraic expressions."
For given example,
A diagram with 5 ovals containing 7 squares,
This means, there is an unknown number X such that:
⇒ X/7 = 5
Now, we can solve the equation for X.
⇒ X/7 = 5
⇒ (X/7) × 7= 5 × 7
⇒ X = 35
Therefore, the division which correctly illustrates a diagram with 5 ovals containing 7 squares is: 35 divided by 7 = 5

PLSS HELP !! ITS DUE SOON , PLSS
Answer:
6.28 meters
Step-by-step explanation:
The formula for circumference is C=2[tex]\pi[/tex]r.
So circumference (C) equals 2 x pi x radius (aka half the diameter)
The diameter is 2 meters, so the radius is 1 meter. (2 meters÷2= 1 meter)
2 x pi (3.14) x 1 = 6.28

Consider a manufacturing process that is producing hypodermic needles that will be used for blood donations. These needles need to have a diameter of 1.65 mm-too big and they would hurt the donor (even more than usual), too small and they would rupture the red blood cells, rendering the donated blood useless. Thus, the manufacturing process would have to be closely monitored to detect any significant departures from the desired diameter. During every shift, quality control personnel take a sample of several needles and measure their diameters. If they discover a problem, they will stop the manufacturing process until it is corrected.
a. Define the parameter of interest in the context of this study and assign an appropriate symbol to it.
b. State the appropriate null and alternative hypotheses using the symbol defined in (a).

The consequence of this is that the wrongfully rejecting a batch of needles because the company do not find strong evidence that its true mean diameter is 1.65 mm whereas it is
d
Gnerally type II error occurs when the null hypothesis is wrongfully accepted
The consequence of this is that the wrongfully accepting a batch of needles because the company do find strong evidence that its true mean diameter is 1.65 mm whereas it is not
Step-by-step explanation:
Generally from the question we are told that
The needle needs to have a diameter of 1.65 mm
Now statistically the parameter of interest in the context of this study is the true mean diameter of the needle and the symbol is [tex]\mu[/tex]
The null hypothesis is [tex]H_o : \mu = 1.65 \ mm[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 1.65[/tex]
Gnerally type I error occurs when the null hypothesis is wrongfully rejected
The consequence of this is that the wrongfully rejecting a batch of needles because the company do not find strong evidence that its true mean is 1.65 mm whereas it is
Gnerally type II error occurs when the null hypothesis is wrongfully accepted
The consequence of this is that the wrongfully accepting a batch of needles because the company do find strong evidence that its true mean is 1.65 mm whereas it is not
