Answer:
11.8 ;
0.1036360
Step-by-step explanation:
Mean births per day, μ = number of births per year / number of days in a year ;
4310 / 365 = 11. 8 births per day
From poisson distribution :
P(x) = (μ^x * e^-μ) ÷ x!
P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!
P(x = 13) = 6.453438E8 / 13!
P(x = 13) = 0.1036360
If the mean of 6 10 12 x 16 18 is 15 find the value of x
Answer:
x=28
Step-by-step explanation:
I am assuming the mean is arithmetic mean. So we first add up the numbers:
6+10+12+18+16+x
=22+10+30+x
=22+40+x
=62+x
Then since there's 6 numbers in total, we have an equation:
[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]
The answer is 28!
Have a nice day! :)
i need answer for this
Answer:
y=5.4
Step-by-step explanation:
So first we cross multiple.
2*112=35*(y+1)
224=35y+35
-35 on both sides
189=35y
÷35 on both sides
5.4=y

State true or false. If 9 is the solution of variable x in the equation fraction numerator 5 straight x space minus space 7 space over denominator 2 end fraction space equals space straight y, then the value of y is 28
Answer:
False
Step-by-step explanation:
Based on what is stated in the question :
Expressing the worded equation Mathematically,
(5x - 7) / 2 = y
If y = 28
(5x - 7) / 2 = 28
Cross multiply
5x - 7 = 28 * 2
5x - 7 = 56
5x = 56 + 7
5x = 63
x = 63 / 5
x = 12.6
Hence, x ≠ 9
2) Solve the system of equations using substitution.
2x -- 9y = 14
x = -6y +7
Answer:
x= 7, y=0 (7,0)

Answer:
Step-by-step explanation:
a=1
r=-6/1=-6
[tex]S_{7}=a\frac{1-r^n}{1-r} =1\frac{1-(-6)^7}{1-(-6)} \\=\frac{1+6^7}{1+6} \\=\frac{1+279936}{7} \\=\frac{279937}{7} \\=39991[/tex]

Select all values that would make the following inequality true: x ≥ -10
-10
-14
-2
0
Answer: -10; -2; 0
Step-by-step explanation:
≥ means greater or equal than.
-10 is equal -10, true.
-14 is less than -10, so false.
-2 is greater than -10, true
0 is greater than -10, true
so the answer is -10, -2 and 0 can make this inequality true.

f(x)1/x please help me
Answer:
You are going to take the shape and flip if across the x Axis, reversing it essentially. then you will move it up 4, so of it is a square with one corner at (2,3) it will go to (5, 7) and all the other point will move together if I remember right. I last did this 3 years ago, I hope I help, next time show the whole graph with the number and I would have put a visual to show you the answer. Good luck
which relation represents a function?
Answer:
the last one is the answer I thin
Answer:
D
Step-by-step explanation:
Hey There!
Remember in order for the relation to be a function none of the x values can repeat
For the first one the x value 0 repeats therefore it is not a function
for the second one the x value -7 repeats thus meaning that its not a function
for the third one the x value 6 repeats hence, it is not a function
for the last one each input has a different output therefore it is a function

Answer:
1) 4 hours 2) 144 miles 3) 12 miles
Step-by-step explanation:
60/5=12
72/6=12
120/10=12
180/15= 12
1) 48 miles / 12 miles = 4 hours
2) 12 hours x 12 miles = 144 miles
3) 1 hour x 12 miles = 12 miles
What is the standard form of the following equation?
y= 2(x - 1)^2 + 4
A) y = 2x2 + 4
B) y = 2x² - 4x + 8
C) y = 2x2 – 2x + 4
D) y= 2x2 - 4x + 6
y = 2(x - 1)² + 4
y = 2(x² - 2x + 1) + 4
y = 2x² - 4x + 2 + 4
y = 2x² - 4x + 6
Ken had 80 rubber bands, he sold 10 and 10
got damaged. How many good rubber bands
were left with Ken? What percentage of
rubber bands were left?
Answer:
60 were left with Ken, and that is 75%
Step-by-step explanation:
80-10 = 70
70-10 = 60
60/80 = x/100, simplify & cross multiply
6/8 = x/100
600 = 8x
x = 75

If a coordinate was dilated from (-3, 2) to (-6, 4), what was the scale factor used?
Given:
A coordinate pair was dilated from (-3, 2) to (-6, 4).
To find:
The scale factor.
Solution:
We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.
The value of scale factor is:
[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]
[tex]k=\dfrac{-6}{-3}[/tex]
[tex]k=2[/tex]
Therefore, the scale factor is 2.
Help Me, Now! C. At what value of x will each function equal 90? Both functions will equal 90 when x =
Answer:
When x=2
Step-by-step explanation:
Well in the first one it tells you that 2x is 90.
In the second it's y=40x+10
So you plug 2 in as the x.
y=40(2)+10
y=80+10
y=90
