Answer:

0.7692077

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of aces in a standard deck = 4

Number of clubs in a standard deck = 13

Probability = required outcome / Total possible outcomes

P(ace) = 4 / 52 = 0.0769

P(club) = 13 / 52 = 1/4 = 0.25

P(not club) = 1 - p(club) = 1 - 0.25 = 0.75

P(ace and not club) = 3/52 = 0.0576923

P(ace or not club) = p(ace) + p(not club) - p(ace and not club

= 0.0769 + 0.75 - 0.0576923

= 0.7692077

Answer:

do u want it in decimal or fraction? or exact?

Answer:

A. You commute to school by walking 0.5 mile to the bus stop in 10 minutes, then waiting 4 minutes for the bus, then riding the bus for 2 miles in 4 minutes.

B. The slope of the first part (walking) is 0.05

The slope of the second part (waiting) is 0.

The slope of the third part (riding the bus) is 0.5

Step-by-step explanation:

From the graph, you can see that a distance of 0.5 mile was covered in the first 10 minutes of commuting. This means that you walked 0.5 mile for 10 minutes to where you want to wait to board a bus.

Then you spent another 4 minutes in waiting for the bus (14 - 10 = 10), while remaining on the same location. No distance was covered during this time spent, as we can see, the slope is horizontal.

You later got a bus, which travelled, 2 miles (2.5 - 0.5 = 2 miles), from where you boarded the bus to your final destination for a period of 4 minutes (18 - 14 = 4 mins).

In simple terms you can describe your commute as follows:

You commute to school by walking 0.5 mile to the bus stop in 10 minutes, then waiting 4 minutes for the bus, then riding the bus for 2 miles in 4 minutes.

B. Slope = rise/run

Therefore:

The slope of the first part (walking) is [tex] \frac{0.5}{10} = 0.05 [/tex].

The slope of the second part (waiting) is 0. (slope of horizontal line is always 0)

The slope of the third part (riding the bus) is [tex] \frac{2}{4} = 0.5 [/tex].

Answer:

x=−10, 10, 3, −1

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x axis. To find the roots (zeros), replace y with 0 and solve for x.

The zeroes of the polynomial is (x+1) (x-3)(x+ 10) (x- 10).

The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero (0). The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.

By looking at the places on the graph where the graph line intersects the x-axis, one can determine a polynomial's zeros. The zeros of the polynomial are the x-coordinates of the sites where the graph crosses the x-axis.

Given:

[tex]x^4-2x^3-103x^2+200x+300[/tex]

Now, use root rational theorem

=(x+1) [tex]x^4-2x^3-103x^2+200x+300[/tex]/ (x+1)

Now, dividing

= [tex]x^4-2x^3-103x^2+200x+300[/tex]/ (x+1)

=  [tex]x^3-3x^2-100x+300[/tex]

Again,

= (x+1)( [tex]x^3-3x^2-100x+300[/tex])

= (x+1) (x-3)(x+ 10) (x- 10)

Hence, the zeroes of the polynomial is (x+1) (x-3)(x+ 10) (x- 10).

Step-by-step explanation:

Angle ST is equal to 7m, because it is the same length as the bottom of the other triangle.

Angle SU is equal to 8m, as we see on the left side of the first triangle.

m < R is equal to 46, because of the total.

m < Q is equal to 75 because of the measure inside the second triangle.

m < 5 is equal to 59 because of the measure inside the first triangle.

Answer:

It will take him 15 days before all of the math problems finish.

Step-by-step explanation:

8 ÷ 3 = 0.266666667

8 math problem ÷ 30 minutes = math problems per minutes

0.266666667  X 45 = 12

math problems per minute X 45 Minutes = math problems per day

175 ÷ 12 = 14.5833333

math problems per day ÷ math problem = days

Note: It should be s instead of x in profit of factory B.

Given:

Consider the profits of two different clothing factories can be modeled as shown, where  s  is the number of shirts produced at each factory.

Factory A : [tex]-0.06s^2+43s-1600[/tex]

Factory B : [tex]-0.04s^2+32s-1500[/tex]

To find:

The polynomial that represents the difference in the profits at the two plants.

Solution:

Let,

Factory A : [tex]P_1=-0.06s^2+43s-1600[/tex]

Factory B : [tex]P_2=-0.04s^2+32s-1500[/tex]

Difference in the profits at the two plants is

[tex]Difference= P_1-P_2[/tex]

[tex]Difference= -0.06s^2+43s-1600-(-0.04s^2+32s-1500)[/tex]

[tex]Difference= -0.06s^2+43s-1600+0.04s^2-32s+1500[/tex]

[tex]Difference= (-0.06s^2+0.04s^2)+(43s-32s)+(-1600+1500)[/tex]

[tex]Difference= -0.02s^2+11s-100[/tex]

Therefore, the required expression is [tex]-0.02s^2+11s-100[/tex].

Answer:

We know that at  CI of 90% the new study provide evidence to claim that the porcentage of multigenerational households has not change

Step-by-step explanation:

To use Normal Distribution as an approximation of the binomial distribution

and develop a test of proportion we look at the products:

n*p      and  n*q     in the sample

p = 28/580    p = 0,04827    then  q = 0,95173

and     n*p = 580*0,04827 = 27,99 > 5

           n*q = 580*0,95173 =  552 > 5

Hypothesis Test:

p₀ = 4 %   p₀ = 0,04

sample size n = 580

p sample proportion mean   p = 0,04

Chossing a confidence Interval  CI = 90 %   then  α = 10%  α  = 0,1

α/2 = 0,05   and  z(score) = 1,64     z (c) = 1,64

The test is a doble tail test since the question is about difference between the study and the past census

Null Hypothesis                     H₀             p =  p₀

Alternative Hypothesis         Hₐ             p ≠ p₀

To calculate z(statistics) z(s)

z(s) = ( p - p₀ ) / √ p*q/n

z(s) = ( 0,04827 - 0,04 ) * √580 / √0,04827*0,95173

z(s) = 0,00827*24,08/ √0,04594

z(s) = 0,1991/ 0,2143

z(s) = 0,929

Comparing z(s) and z(c)

z(s) < z(c)      ;    0,929  < 1,64

Therefore at CI 90% we accept H₀  since z(s) is in the acceptance region

Answer:

A. Lana saves at a greater rate because her unit rate of $50 per week is greater than Eliana's unit rate of $48 per week.

Step-by-step explanation:

Eliana​'s savings per week = the rate of change of the graph

The rate of change of the graph given = [tex] \frac{y_2 - y_1}{x_2 -x_1} [/tex]

Using the points (0, 0) and (2, 96),

Rate of change = [tex] \frac{96 - 0}{2 - 0} = \frac{96}{2} = 48 [/tex]

This rate of change means, Eliana puts $48 dollars per week into her account.

Since Lana's saving rate per week is $50, therefore:

Lana saves at a greater rate because her unit rate of ​$50 per week is greater than Eliana​'s unit rate of ​$48 per week.

The number vertices does the polyhedron have is 20.

A polyhedron is a three-dimensional structure in geometry that has flat, polygonal faces, edges that are straight, and sharp vertices. A convex polyhedron is made up of finitely many points that are not all on the same plane and has a convex hull. Convex polyhedra include shapes like cubes and pyramids.

Using Euler formula

F + V = E + 2

As, From the figure the faces = 7 and edges = 30

12 + V = 30 + 2

12 + V = 32

V = 32- 12

V= 20

Answer:

0.063 is the probability of at least 31 students.

Step-by-step explanation:

Solution:

Given:

The age distribution of students  is given below:

Age (years) Number of students

Under  21                    414

21 - 25                         413

26 - 30                        212

31 - 35                        50

0ver 35                     20

total                         1109

A student from community college is selected at random.

The ratio  of favorable outcomes numbers of that event is the probability of  to the total number of possible outcomes in experiment.

Probability of at least 31 students:

Probability of At least 31 students = 31 or more than 31 students

P( 31 – 35) = n (31 – 35) + n (over 35) / n(T)

= 50 + 20 / 1109

= 70 / 1109

= 0.063

0.063 is the probability of at least 31 students.
