What is the probability of rolling an even number on the first roll of a number cube and rolling an odd number on the second roll?
Answers
Answer:
1/4.
Step-by-step explanation:
There are 3 even numbers in the 6 numbers on a cube.
So Probability first roll is even = 3/6 = 1/2.
By the same reason Probability of odd number = 1/2.
So: Probability(First is even and second is odd) = 1/2 * 1/2 = 1/4.

A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc. in degrees?
Answers
Answer:
60°Step-by-step explanation:
Given that:
Circumference (C) = 6 unitsArc length (A) = 1 unitFind the central angle (θ)
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6
θ = 60° ✅Central angle = 60°

Select the correct answer. One factor of the polynomial 2x^3–3 x^2 - 3x + 2 is (x- 2), which expression represents the other factor, or factors, of the polynomial?
Answers
Answer:
D
Step-by-step explanation:
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.
The given expressions are 2x³-3x²-3x+2 and x-2.
What are factors of polynomial?The factors are the polynomials which are multiplied to produce the original polynomial.
Here, the given polynomial can be factored as follows:
x-2 |2x³-3x²-3x+2| 2x²+x-1
2x³-4x²
(-) (+)
___________
x²-3x+2
x²-2x
(-) (+)
___________
-x+2
-x+2
(-) (+)
____________
0
2x²+x-1 can be rewritten as 2x²+2x-x-1
= 2x(x+1)-(x+1)
= (x+1)(2x-1)
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

The numerator of a fraction is 2 less than the denominator. A new fraction can be formed by adding 5 to the denominator and doubling the numerator. The product of the original fraction and the reciprocal of the new fraction is 1/4. What is the original fraction?
Answers
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
let the denominator of the original fraction be x, then
[tex]\frac{x-2}{x}[/tex] ← original fraction
Then
[tex]\frac{2(x-2)}{x+5}[/tex] ← new fraction
The product of original and reciprocal of new is
[tex]\frac{x-2}{x}[/tex] × [tex]\frac{x+5}{2(x-2)}[/tex] ← cancel (x - 2)
= [tex]\frac{x+5}{2x}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )
4(x + 5) = 2x
4x + 20 = 2x ( subtract 2x from both sides )
2x + 20 = 0 ( subtract 20 from both sides )
2x = - 20 ( divide both sides by 2 )
x = - 10
Then original fraction
[tex]\frac{x-2}{x}[/tex] = [tex]\frac{-12}{-10}[/tex] = [tex]\frac{6}{5}[/tex]

A line that includes the point (1, 10) has a slope of 6. What is its equation in slope-intercept
form?
Answers
Answer:
y = 6x + 4Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = 6
(1, 10) ⇒ x₀ = 1, y₀ = 10
Therefore:
y - 10 = 6(x - 1) ← the point-slope form
y - 10 = 6x - 6 {add 10 to both sides}
y = 6x + 4 ← the slope-intercept form

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 105 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?
Answers
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used
You rent an apartment that costs $ 1400 $1400 per month during the first year, but the rent is set to go up $ 190 $190 per year. What would be the monthly rent during the 6th year of living in the apartment?
Answers
Answer:
$2540
Step-by-step explanation:
Given data
Cost per month=$1400
Increase per year=$190
Time = 6 years
Let the total rent per month be y
Hence, the expression for the monthly rent after 6 years is
y= 1400+190(6)
y= 1400+1140
y=$2540
