Slove the system
Answers
Y = 10
3x + 2y = 26
Y = 5x
3x + 2(5x) = 26
3x + 10x = 26
13x = 26
X = 2
Y = 5 (2)
Y = 10
Answer = 2
Step-by-step explanation:
3x + 2(5x) = 26
3x + 10x = 26
13x = 26
26 ÷ 13 = 2

A large company states in its promotional literature that 74% of its employees have college degrees. Assume this claim is true. If 3 employees are selected at random from this company, what is the probability that at least 1 of the selected employees will not have a college degree?
A. 0.0176
B. 0.4052
C. 0.5948
D. 0.9284
Answers
Answer:it is 0.5948
Step-by-step explanation:c
The probability that at least 1 of the selected employees will not have a college degree is 0.594776.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]
Where,
x is the number of successes needed,n is the number of trials or sample size,p is the probability of a single success, andq is the probability of a single failure.Given that 74% of the employees have degrees, therefore, 26% of the employees have no degree.
Now, since we want at least any one of the three people selected to have a degree. Therefore, the probability of everyone having a degree can be written as,
Probability that at least any one of the three people selected to have a degree = 1 - Probability of everyone having a degree
Now, using the binomial distribution we can write,
[tex]\text{Probability} = 1 - [^3C_0\cdot(0.26)^0 \cdot (0.74)^{(3-0)}]\\\\\text{Probability} = 1 - 0.405224 = 0.594776[/tex]
Hence, the probability that at least 1 of the selected employees will not have a college degree is 0.594776.

An angle measures 160° less than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10

Peter is renting two kinds of rafts for a vacation company. One type seats 3
people and the other seats 5 people. If 53 people are using the vacation
company and he rents 13 rafts, how many of each type of raft does he rent?
Answers
Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].
It's always a good idea to put these equations under each other:
[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]
We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]
Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

for each sequence find the first 4 terms and the tenth term
a) n squared +3
b) 2n squared
Answers
Answer:
Step-by-step explanation:
Given that:
a) n³
The first 4 terms are;
let assume n = 1
1³ = 1
if n = 2
2³ = 8
if n= 3
3³ = 27
if n = 4
4³ = 64
So, the sequence is 1, 8, 27, 64
The tenth term of this sequence is: 10³ = 1000
b)
2n²
if the first term is 1
then 2(1)² = 2
if n = 2
2(2)² = 8
if n = 3
2(3)² = 18
if n = 4
2(4)² = 32
So, the sequence is 1, 8, 18, 32
The tenth term will be 2(10)² = 200
