The given equation is,

So, from this equation , we have to find the value of x. The left hand side of the equation has x with 1/3 as coefficient, therefore, inorder to make it x, we have to,

as the thress get cancelled. If we do some operation on one side of the equal sign, it is to be applied on the other side also so as to maintain the equivalency.

So here we have to multiply by 3.

But in option, there is no as such given , but it is given that divide by 1/3.

which is equuivalent to multiplying by three.

So the option " Divide by 1/3" is correct.

The probability of matching x successes on n further trials in an experiment with two possible outcomes. There is a 4.88% chance that no one is worried that their employers are listening to their phone calls.

Given that,

The probability of matching x successes on n further trials in an experiment with two possible outcomes is known as the binomial probability (commonly called a binomial experiment).

The following formula gives it:

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

Where is the number of distinct combinations of x items drawn from a set of n elements, as determined by the formula below.

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

And p is the probability that anything will happen.

Being aware that employers are monitoring phone calls is a victory in this issue.

43% of adults fear that their employers are listening to their phone calls,

p=43%=0.43

We must locate Four persons were questioned, and none expressed concern about phone call monitoring by companies.

We count four adults, n=4.

Is there a probability of success of 0? If so, then x = 0.

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

[tex]P=C_{4,0}(0.43)^{0}.(0.57)^{4}[/tex]

P=0.0488

Therefore, There is a 4.88% chance that no one is worried that their employers are listening to their phone calls.

Step-by-step explanation:

if x is the number of months

Rodney's equation: y=40x+75

Morgan: y = 50x + 40

Equate them together:

50x+40 = 40x+75

10x=35

x=3.5

Yes, after 3 and a half months, they will both have 215$ in their account.

Is this a simple random sample: Yes, because each student and sample of 100 has the same chance of being selected.

A simple random sample can be defined as a subset of items that are selected from a larger data set or statistical population, with each member of the subset having an equal or the same probability (chance) of being selected.

This ultimately implies that, each member of the subset are selected by chance and randomly, and as such a simple random sample is an unbiased representation of a larger data set or a statistical population.

In this context, we can reasonably infer and logically deduce that the data set or statistical population described in this scenario is a simple random sample.

The area of a triangle is 1/2 x base x height.

The area of a triangle is 24.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices

The area of a triangle is given by:

Area = 1/2 x base x height

We have,

A triangle ABC.

Angle bisectors are AD, BE, and CF, which intersect at I as shown in the figure below.

DI = 3

DI = AI = 3

Height of the triangle = AD = AI + DI = 3 + 3 = 6

BD = 4 = BC

Base of the triangle = BC = BD + DC = 4 + 4 = 8

The area of a triangle:

= 1/2 x base x height

= 1/2 x 8 x 6

= 1 x 4 x 6

= 24

Thus,

The area of a triangle is 24.

Answer: Melissa sleeps for 8 hours and wakes up at 7 am.

Step-by-step explanation: For this i was able to do just eliminate some answer. "Melissa sleeps for 7 hours and wakes up at 8 am," in this case Melissa would drink coffee because she slept less than 8 hours. "Melissa sleeps for 9 hours and wakes up at 5:30 am," in this case Melissa would drink coffee since she had woke up at 5:30 am. "Melissa sleeps for 7 hours and wakes up at 6 am," in this case Melissa would drink coffee since she had less than 8 hours of sleep. In conclusion, The only time Melissa wouldn't had drank coffee is when she had slept for 8 hours and woke up at 7 am. That is because had slept more than 8 hours and had woke up after 7 am.

The expression of the fraction 10¹/₅ - 2¹/₆ as a mixed fraction is;  8¹/₃₀

We want to subtract two fractions.

Now, fractions could be either proper fraction, improper fraction or mixed fraction.

Now, a proper fraction simply means the numerator is smaller than the denominator, a mixed fraction simply means a whole number and a proper fraction while an improper fraction simply means the numerator is bigger than the denominator

We are given the operation;

10¹/₅ - 2¹/₆

Converting to improper fraction gives;

51/5 - 13/6

Factorizing gives us;

1/30((51 * 6) - (13 * 5))

= 241/30

C(6,0)

step 1

Find out the slope AB

m=(2-0)/(3-2)

m=2/1

m=2

Remember that

If two lines are perpendicular, then, their slopes are negative reciprocal

so

the slope of the altitude that passes through C is -1/2

Find out the equation of the altitude that passes through C

y=mx+b

we have

m=-1/2

point C(6,0)

substitute

0=-(1/2)(6)+b

solve for b

0=-3+b

b=3

equation is y=-(1/2)x+3 -------> equation 1

step 2

Find out the slope BC

m=(0-2)/(6-3)

m=-2/3

so

the slope of the altitude that passes through A is 3/2

Find out the equation of the altitude that passes through A

y=mx+b

we have

m=3/2

point A(2,0)

0=(3/2)(2)+b

solve for b

0=3+b

b=-3

y=(3/2)x-3 ------> equation 2

The interest she pays over 4 weeks is #5000 and the interest she pays per week is #1250.

According to the question,

We have the following information:

A woman borrows #20 000 for 4 weeks.

She agrees to pay #25 000 back at the end of the 4 weeks.

Now, we will subtract the borrowed amount from the amount paid after 4 weeks to find the interest paid after 4 weeks.

(a) Interest paid over 4 weeks = #(25000-20000)

Interest paid over 4 weeks = #5000

(b) Now, we can easily find the interest paid per week by the interest paid over 4 weeks by the total number of weeks.

Interest paid per week = Interest paid in 4 weeks/4

Interest paid per week = 5000/4

Interest paid per week = #1250

Hence, the answers to part a is #5000 and the answer to part b is #1250.
