Answer:
0.61596
Step-by-step explanation:
Given that:
λ = 5 (5 errors per page)
Poisson distribution formula :
P(x = x) = (λ^x * e^-λ) / x!
Probability that page does not need to be retyped means that error on page is less than or equal to 5
P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)
The individual probabilities can be obtained using the formula above or the use of a calculator
P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674
P(x ≤ 5) = 0.61596
simplfy the expression and combine like terms 4 (x - 2) + 2 (x + 1)
Answer:
6x-6
Step-by-step explanation:
First you use the order of operations and multiply 4(x)+4(-2)=4x-8 and then 2(x)+2(1)=2x+2. Then you add it all together, 4x+2x+2-8=6x-6.

The PTA plans a spring carnival on a Saturday in April. If it's a sunny day, they estimate
that they will make $3,000, but if it rains, they will lose $600 because nobody will come.
There's a 30% chance of rain on Saturday. Create a probability model.
Answer:
The probability model is
= P(A or B)
Step-by-step explanation:
a) Data and Calculations:
Estimated revenue if the day is sunny = $3,000
Estimated loss if the day is rainy = $600
The probability of rain = 30%
Therefore, the probability of sunshine = 70% (100 - 30)
The probability model is based on the probability of rain or sunshine
= P(A or B)
= A*70% - B*30%
The outcome from either rain or sunshine
= ($3,000 * 70%) -($600 * 30%)
= $2,100 - $180
= $1,920

y=-2x+3
× -2, -1, 0, 1
Answer:
If x = -2, -1, 0, 1, then (In this order) y = 7, 5, 3, 1
Step-by-step explanation:
If you put in each value of "x" into the equation, you'll get the appropriate "y".
y= -2(-2)+3
y= 4+3
y= 7
y= -2(-1)+3
y= 2+3
y= 5
y= -2(0)+3
y= 0+3
y= 3
y= -2(1)+3
y= -2+3
y= 1
What is the estimated probability that at least two of the puppies will be
female?
O A. 5/10 = 50%
O B . 8/10 = 80%
O C. 3/10 = 30%
O'D. 7/10 = 70%
Given:
The results of the simulation.
Number of puppies = 4
To find:
The estimated probability that at least two of the puppies will be female.
Solution:
Let heads (H) = Female puppy.
Let tails (T) = Male puppy.
The results of the simulation are HHHH, TTTH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH, THTT.
Total outcomes = 10
The results having 2 or more H are HHHH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH.
Favorable outcomes = 8
Now,
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{8}{10}[/tex]
Probability in % is
[tex]\text{Probability}\%=\dfrac{8}{10}\times 100[/tex]
[tex]\text{Probability}\%=80\%[/tex]
The estimated probability that at least two of the puppies will be female is [tex]\dfrac{8}{10}=80\%.[/tex]
Therefore, the correct option is B.

Answer:
8
Step-by-step explanation:
40 + 5 (at the door)=45
(president's goal) 400 divided by 45= approximately 8

A) side angle side triangle congruence
B) angle side angle triangle congruence
C) side side side triangle congruence
D) side side angle triangle congruences
Answer:
B) angle side angle triangle congruence
Step-by-step explanation:
In the diagram given, the two angles, <A and <E, and the included side, AE, are congruent to the corresponding two angles, <C and <E, and corresponding included side, CE.
Therefore, based on the ASA Congruence Theorem, we can conclude that both triangles are congruent to each other.

Rajeev deposits $800 in a savings account earning interest at a rate of 4% compounded annually. How much is in his account after five years?
Answer:
960
Step-by-step explanation:
We know that 4 percent of 800 dollar is 32 dollar. So 32 time 5 (because it ask us how much after 5 year) is 160. Now we add it to 800 because it ask the total in his account so it 960.
After five years, Rajeev have $960 in his account.
What is mean by Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
Rajeev deposits $800 in a savings account earning interest at a rate of 4% compounded annually.
Here, Principal amount = $800
Rate = 4%
Time = 5 years
Hence,
Interest = PRT/100
= 800 x 4 x 5 / 100
= 160
Thus, Total amount after 5 years is,
⇒ 800 + 160
⇒ $960
Therefore, After five years, Rajeev have $960 in his account.

Given the following roots identify additional roots 10 and √3
Given:
Two roots of a function are 10 and [tex]\sqrt{3}[/tex].
To find:
The additional roots.
Solution:
According to irrational root theorem, if [tex]\sqrt{b}[/tex] is a root of a function, then [tex]-\sqrt{b}[/tex] is also a root of than function.
Two roots of a function are 10 and [tex]\sqrt{3}[/tex].
Using irrational root theorem, we can say that [tex]-\sqrt{3}[/tex] is also a root of that function.
Therefore, the additional root is [tex]-\sqrt{3}[/tex].
