Step-by-step explanation:
The arrow on each of the spinners with be spun one time .which of the following shows all the possible outcome when each spinner is spun once .
Answer:
Option (2)
Step-by-step explanation:
If we spin spinner 1, the possible outcome on this spinner for a single spin will be either RED (R) or GREEN (G).
Similarly, if we spin spinner 2, possible outcomes for a single spine will be 1 or 2 or 3 or 4.
If we spin both the spinners possible outcomes from both the spinners in a single spin will be,
Red with 1 Or Red with 2 Or Red with 3 Or Red with 4,Or
Green with 1 Or Green with 2 Or Green with 3 Or Green with 4
Symbolically,
R1, R2, R3, R4, G1, G2, G3, G4
Therefore, Option (2) will be the answer.
the sum of 2 numbers is 21 the second number is six times the first
Answer:
[tex]\huge\boxed{\text{Numbers: 3, 18}}[/tex]
Step-by-step explanation:
We can create two equations and solve the system of equations to find both the numbers. Let's represent the numbers as a and b.
We can create two equations:
[tex]a+b=21[/tex]
[tex]b=6a[/tex]
We can now substitute the value of b (6a) into the first equation.
[tex]a + (6a) = 21[/tex]
Combine like terms:
[tex]7a=21[/tex]
Divide both sides by 7:
[tex]a=3[/tex]
Now we know the first number is 3. We can plug this value into one of the equations to find b. Let's plug it into [tex]b=6a[/tex].
[tex]b = 6 \cdot 3\\\\b = 18[/tex]
So our numbers are 3 and 18.
Hope this helped!
Step-by-step explanation:
We can create two equations and solve the system of equations to find both the numbers. Let's represent the numbers as a and b.
We can create two equations:
a+b=21a+b=21
b=6ab=6a
We can now substitute the value of b (6a) into the first equation.
a + (6a) = 21a+(6a)=21
Combine like terms:
7a=217a=21
Divide both sides by 7:
a=3a=3
Now we know the first number is 3. We can plug this value into one of the equations to find b. Let's plug it into b=6ab=6a .
b=6⋅3
b=18
So our numbers are 3 and 18.

on a piece of paper graph y≥2x
Answer:
Step-by-step explanation:
I don't have a graph but I'll tell you how to graph. You have to graph this as an mx+b equation. Since this doesn't have a y-intercept, you'll start at 0 on the graph. Go up 2 times and over to the right 1 time. You should be at (1,2) do the same thing and you should be at (2,4) continue till you run out of the provided space. Now, go back to 0 and complete the part below it. To complete that, from 0, go down 2 times and over to the left 1 time. You should reach (-1,-2) and when you do the same thing again, you should reach (-2,-4) and continue until you run out of space. The coordinates o=in which the line touches should be the opposites of the coordinates above 0. Like (1,2) (-1,-2) and (2,4) (-2,4).
How many ways can a store manager arrange a group of 1 team leader and 3 team workersfrom his 25 employees
Answer:
2300 waysStep-by-step explanation:
in this problem, we are expected to use commination to arrive at a solution
Given data
number of employee= 25
number of team=3
The expression for combination is given as
C(n,r)=(nr)=n!/(r!(n−r)!)
C(25,3)=25!/(3!(25−3)!)
C(25,3)=25!/(3!(22!)
C(25,3)=25*24*23*22!/3!(22!)
C(25,3)=25*24*23*/3!
C(25,3)=25*24*23*/3*2*1
C(25,3)=25*24*23*/6
C(25,3)=13800/6
C(25,3)=2300 ways
The number of ways where a store manager arranges a group is 50,600.
Given that,
There is a group of 1 team leader and 3 team workers from his 25 employees.Based on the above information, the calculation is as follows:
[tex]= ^25C_4 \times 4C_1\\\\= \frac{25!}{4!(25-4)!} \times \frac{4!}{1!(4-1)!} \\\\= \frac{25!}{4! \times 21!} \times \frac{4!}{1! \times 3!} \\\\= 12,650 \times 4[/tex]
= 50,600
Therefore we can conclude that the number of ways where a store manager arranges a group is 50,600.

minutes. At this rate, how many cakes can
Francine decorate in one hour?
None of the Above
Answer:
Francine can decorate 9 cakes in 1 hour.
Step-by-step explanation:
Since there are sixty minutes in an hour, knowing that 20 × 3 = 60, all you have to do is multiply 3 by itself to get 9.

Step-by-step explanation:
The measures of two vertical angles are 58° and (3x + 4)". Find the value of x.
Answer:
x = 18°
Step-by-step explanation:
Vertical angles can be defined as a pair of angle formed when two (2) lines intersect. These angles formed during the intersection of the two (2) lines are opposite to each other.
Hence, vertical angles are always equal to one another.
From the question, we have;
58° = (3x + 4)°
Rearranging the equation;
[tex] 3x = 58 - 4[/tex]
[tex] 3x = 54[/tex]
[tex] x = \frac{54}{3}[/tex]
x = 18°
Therefore, the value of x is 18 degrees.

For questions 2 and 3. It is known that the mean diameter of pine trees in a national forest is 9.6 (inches) with a standard deviation 2.4 (inches). Assuming that the tree diameters are distributed normally. If a pine tree is to be selected randomly from this forest, what is the probability that its diameter will fall between 7.2 inches and 14.4 inches?
Answer: 0.8185
Step-by-step explanation:
Let X represents the tree diameters that are distributed normally.
Given: Mean [tex]\mu=9.6\text{ inches}[/tex], Standard deviation [tex]\sigma=2.4\text{ inches}[/tex]
The probability that its diameter will fall between 7.2 inches and 14.4 inches will be:
[tex]P(7.2<X<14.4)=P(\dfrac{7.2-9.6}{2.4}<\dfrac{X-\mu}{\sigma}<\dfrac{14.4-9.6}{2.4})\\\=P(-1<Z<2)\ \ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=P(Z<2)-P(Z<-1)\\\\=P(Z<2)-(1-P(Z<1))\\\\=0.9772-(1-0.8413)=0.8185\ [\text{By p-value table}][/tex]
Hence, required probability = 0.8185

Find equation for a vertical line passing through the point (-12,-4)
Answer:
x = -12
Step-by-step explanation:
This is a vertical line, so the equation will be of the form x = k, where k is any x-value.
The conclusion that x = -12 was found because the x-value in the point was -12.

A population has a mean of 200 and a standard deviation of 50. Suppose a random sample of 100 people is selected from this population. What is the probability that the sample mean will be within /- 5 of the population mean
Complete Question
A population has a mean of 200 and a standard deviation of 50. Suppose a random sample of 100 people is selected from this population. What is the probability that the sample mean will be within [tex]\pm 5[/tex] of the population mean
Answer:
The value is [tex]P(195 < X < 205 ) = 0.6827 [/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 200[/tex]
The population standard deviation is [tex]\sigma = 50[/tex]
The sample size is [tex]n = 100[/tex]
Generally the standard error of sample mean is mathematically represented as
[tex]s = \frac{ \sigma }{\sqrt{n} }[/tex]
=> [tex]s = \frac{50 }{\sqrt{100} }[/tex]
=> [tex]s =5[/tex]
Generally the limits of [tex]\pm 5[/tex] within the population mean is mathematically represented as
[tex]a = \mu - 5[/tex]
=> [tex]a = 200 - 5[/tex]
=> [tex]a = 195[/tex]
and
[tex]b = \mu + 5[/tex]
=>[tex]b = 200 + 5[/tex]
=>[tex]b = 205[/tex]
Generally the probability that the sample mean will be within [tex]\pm 5[/tex] of the population mean is mathematically represented as
[tex]P(a < X < b ) = P(\frac{a - \mu }{s} < \frac{X - \mu }{s} < \frac{b - \mu }{s} )[/tex]
=> [tex]P(195 < X < 205 ) = P(\frac{ 195- 200 }{5} < \frac{X - \mu }{s} < \frac{205 - 200 }{5} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(195 < X < 205 ) = P(-1< Z<1 )[/tex]
=> [tex]P(195 < X < 205 ) = P(Z < 1) - P(Z<-1 )[/tex]
Generally from the z -table the probability of (Z < 1) and (Z<-1 ) is
[tex]P(Z < 1)= 0.84134[/tex]
and
[tex] P(Z<-1 ) = 0.15866 [/tex]
So
[tex]P(195 < X < 205 ) = 0.84134 - 0.15866 [/tex]
[tex]P(195 < X < 205 ) = 0.6827 [/tex]
