Step-by-step explanation:

Answer:

A.

x = 30

y = 10√3

Step-by-step explanation:

Reference angle = 30°

Opposite = y

Adjacent = x

Hypotenuse = 20√3

✔️To find x, apply CAH:

Cos 30 = Adj/Hyp

Cos 30 = x/20√3

20√3 × Cos 30 = x

20√3 × √3/2 = x (cos 30 = √3/2)

(20√3 × √3)/2 = x

(20 × 3)/2 = x

60/2 = x

30 = x

x = 30

✔️To find y, apply SOH:

Sin 30 = Opp/Hyp

Sin 30 = y/20√3

20√3 × Sin 30 = y

20√3 × ½ = y (sin 30 = ½)

(20√3 × 1)/2 = y

(20√3)/2 = y

10√3 = y

y = 10√3

Answer: Chad Makes $1.50 more

Step-by-step explanation:

You have to divide 30 from 4 to see Horatio’s hourly rate which is 7.5 and then you will see that 9 - 7.5 is 1.5. I hope this helped

[tex]x = \frac{ac + b}{2c - ab} [/tex]

Refer to the attachment for step by step explaination.

Answer:

[tex]x=\frac{b+ax}{2c-ba}[/tex]

Step-by-step explanation:

When given the following expression, one is asked to solve for (x):

[tex]\frac{2x-a}{b}=\frac{ax+1}{c}[/tex]

Use cross products to rid the variable in the denominator,

[tex]c(2x-a)=b(ax+1)[/tex]

Simplify, distribute, multiply every term in the parenthesis by the term outside of it,

[tex]2xc-ac=bax+b[/tex]

Inverse operations, collect all terms with variable (x) on one side of the equation:

[tex]2xc-ac = bax + b\\\\2xc - bax = b + ac[/tex]

Factor, remove a like term that exists in both of these expressions,

[tex]x(2c-ba)=b+ax[/tex]

Inverse operations,

[tex]x=\frac{b+ax}{2c-ba}[/tex]

OPTION A , C,D

are the correct choices because all of them are equal to √5

Answer:

Line DC.

Step-by-step explanation:

Point D and Point C are not connected and, therefore, do not form a line.

Geometry

DC is not a line, due to it not being connected.

Answer:

Solution given:

CD=18m

In ∆ ACD

Tan 35=opposite/adjacent

Tan 35=CD/AC

AC=18/Tan35

AC=25.7m

again

In ∆ BCD

Tan 60=opposite/adjacent

Tan 60=CD/BC

BC=18/tan60

BC=10.4

we have

AC=AB+BC

AB=25.7-10.4

AB=15.3

Distance between A and B point is 15.3 metre

Answer:

Time, t = 5 seconds.

Step-by-step explanation:

Given the following data;

Initial velocity = 16 ft/s

Height = 480 ft

Acceleration due to gravity = 32 ft/s²

To find how much time it will take the ball to reach the ground, we would use the kinematic equation given by the formula;

[tex] d = V_{i}t + \frac {1}{2}at^{2} [/tex]

Where;

Substituting into the equation, we have;

[tex] 480 = 16t + \frac {1}{2}*32t^{2} [/tex]

[tex] 480 = 16t + 16t^{2} [/tex]

Dividing all through by 16, we have;

[tex] 30 = t + t^{2} [/tex]

Re-arranging the quadratic equation, we have;

[tex] t^{2} + t - 30 = 0 [/tex]

We would solve the quadratic equation by factorization;

[tex] t^{2} + 6t - 5t - 30 = 0 [/tex]

[tex] t(t + 6) - 5(t + 6) = 0[/tex]

[tex] (t + 6)(t - 5) = 0 [/tex]

t = -6 or 5

Since we know time can't be negative, we would ignore the value of -6.

Therefore, time = 5 seconds

Step-by-step explanation:

A density curve for all the possible ages between 0 years and 25 years on the shape of a triangle. 0.04

Answer:

here we have:

x = 5*t + 3

y = 2*t - 6

both for -2 ≤ t ≤ 3

First, we can rewrite:

x = a*y + b

let's try to find the values of a and b.

5*t + 3 = a*(2*t - 6) + b

5*t + 3 = a*2*t + (b - 6*a)

Here we have two equations:

5 = a*2

3 = (b - 6*a)

from the first one, we can solve:

5/2 = a

replacing this into the second, we et:

3 = b - 6*(5/2)

3 = b - 15

3 + 15 = b = 18

Then:

x = (5/2)*y + 18

y =  2*t - 6

So, y is a linear equation that depends on the variable t

x is a linear equation that only depends on x (from this we already know that the graph will be a line)

and we know that  −2 ≤ t ≤ 3

Then the minimum value of y is:

y = 2*(-2) - 6 = -10

and the largest value of y is:

y = 2*3 - 6 = 0

So y-varies in the range between -10 and 0

And because x =  (5/2)*y + 18

The minimum value of x is:

x = (5/2)*-10 + 18 = -25 + 18 = -7

and the maximum value of x is:

x = (5/2)*0 + 18 = 18

Then we know that this line starts in the point (-10, -7) and ends in the point (0, 18)

Answer:

12 students

Step-by-step explanation:

So we know that 65% of students prefer math over the 35% of students that prefer science.

To find the answer we have to change the percentages to decimals and multiply by 40, which is the total number of students.

Math: 65%=0.65 , so 0.65 times 40=26 students

Science:35%=0.35, so 0.35 times 40=14 students

To find the difference, subtract 26 and 14, to get 12.

All in all, twelve students prefer math over science.

Hope I helped, have a nice day :)

Answer:

Answer is 12 more students prefer math over science.

Step-by-step explanation:

For this question all you need to to is multiply the decimal or the percent by 40 to get the student ratio. So for the math. 40 * .65 = 26. So 26 students like math.

For the science we do 40*35% or if you want to write it decimal form 40*.35 = 14. Okay now we have both values all you need to do to get the difference is subtact 26-14= 12. 12 more students prefer math over science.

Answer:

The answer is "0.052 and 0.056".

Step-by-step explanation:

For option 1:

Your daughter's opportunity (in sport) (when a person only wins once)

[tex]\to \frac{1}{39}+\frac{1}{38}\\\\ \to \frac{38+39}{1,482} \\\\\to \frac{38+39}{1,482} \\\\\to 0.052[/tex]

For option 2:

Your daughter would win a chance (in sport) [tex]= \frac{1}{18} = 0.056[/tex]

So a little better, the second option. The rationale is that there are fewer girls than boys so if a lottery in a smaller group is awarded you are more likely to win.

I would answer, but I don’t see the graph. If you add the graph I could help (if you want of course, not trying to be rude. Sorry!)

Answer:

44.402

Step-by-step explanation:

Equation

SA = 2L*W + 2L*H + 2*WH

Givens

L = 2.7

W=1.13

H = 5

Solution

LW = 2.7 * 1.13  = 3.051

LH = 2.7 * 5  =    13.5

WH = 1.13 * 5  =  5.65

SA = 2*3.051 + 2*13.5 + 2*5.65

SA = 6.102 + 27 + 11.3

SA = 44.402

Answer:

0.0006 = 0.06% probability of this occurrence

Step-by-step explanation:

For each unit, there are only two possible outcomes. Either it is defective, or it is not. The probability of an unit being defective is independent of any other unit, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

An electronics firm claims that the proportion of defective units of a certain process is 5%.

This means that [tex]p = 0.05[/tex]

A buyer has a standard procedure of inspecting 15 units selected randomly from a large lot.

This means that [tex]n = 15[/tex]

a) What is the probability of this occurrence?

Probability of 5 defective items, whch is P(X = 5). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{15,5}.(0.05)^{5}.(0.95)^{10} = 0.0006[/tex]

0.0006 = 0.06% probability of this occurrence

Answer:

5c + 42 and 9c + 2

Step-by-step explanation:

if a number has a variable next to it then it cannot be combined with a number that is alone.. Therefore there is no exact answer unless the variable has a number that you can replace it with. So basically numbers with the same number can be added together and numbers alone can be added together. If you do the math right then you should get the answer.
