Answer:

$350.25 per month

Step-by-step explanation:

We can assume she pays the same amount every month. We know that there are 12 months in a single year, so we can divide to find the unit rate.

4203 / 12 = 350.25

Answer:

642000000000000000000000 kg

Step-by-step explanation:

The approximate mass of Mars is 6.42x10^23 kilograms. It is given in scientic notation.

We need to write the mass in standard notation. It is the normal way of writing any number. To write it in standard form, we move the decimal to the right side.

The standard form will be :

6.42x10^23 kg = 642000000000000000000000 kg

Hence, this is the required solution.

Answer:

The correct option is B.

Step-by-step explanation:

The median (m) is a measure of central tendency. To obtain the m, we assemble the data in arising order. If the data is odd, the m is the mid-value. If the data is even, the m is the arithmetic-mean of the two mid-values.

The mean is the average value of the data set. It is computed by dividing the sum of all the values in data set by the number of values.

So, the mean considers all the values in the data set. But the median considers only one value.

It is provided that the clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest  employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000.

The highest salary will be taken into account while the computation of mean. But it would not be considered while determining the median.

So, the median salary will remain same.  But the mean salary will change.

And since the highest salary is increasing from $150,000 to $1,500,000 the mean will also increase.

Thus, the correct option is B.

Answer:

South =34.18 miles

East=  49.12miles

Step-by-step explanation:

We begin by calculating the distance covered in 7n hours

that is from 12 pm to 7pm which is 7 hours

so time t= 7 hours

speed= 40 miles per hours

we know that speed= distance/time

let the distance be x

40=x/7

x=40*7

x=28miles

(a) many miles south and how many miles east will the boat have traveled at 7 pm

applying SOH CAH TAO we have

For the  south  CAH

cos Ф=hyp/adj

hyp= 28 mile

Ф= 35°

cos 35= 28/adj

0.819=28/adj

adj=28/0.819

adj=34.18 miles

For the  East SOH

sin Ф=hyp/opp

hyp= 28 mile

Ф= 35°

sin 35= 28/opp

0.57=28/opp

opp=28/0.57

opp=49.12miles

Answer:

The value of m (slope) is -3

The value of b (y-intercept) is -6

Step-by-step explanation:

First you need to isolate y:

3x + y = −6

y = -3x - 6

The value of m (slope) is -3

The value of b (y-intercept) is -6

Answer: 20 apples

Step-by-step explanation:

If 15 oranges is represented as 3, this means it was divided by 3.

15 ÷ 3 = 5

Now, get the number 5 and multiply it by 4.

5 × 4 = 20

The answer is 20 apples. Hope this helps!

Answer:

72 cards

Step-by-step explanation:

There are 8 playing cards in each row, with 9 rows in all.

To solve, simply multiply the two numbers together:

8 playing cards per row x 9 rows = 72 playing cards in all.

72 cards is your answer.

Answer:

310

Step-by-step explanation:

9.87 = 10 its 10 because 87 is over 50 so its closer to 10

0.509 = 1 50 is close to 100 which is 1

31 times 10 = 310

310 divide by 1

equals 310

Answer:

Step-by-step explanation:

Given the height of the drone modelled by the equation:

h(t)=-3t^2+12t+96

a) Rewriting this in a factored form.

From the equation, we can see that -3 is the greatest common factor. The equation therefore becomes:

h(t)= -3(t^2-4t-32)

Hence the function can also be written as h(t)= -3(t^2-4t-32)

b) The drone landed on the ground at when h(t) = 0. Substitute h(t) = 0 into the expression  h(t)= -3(t^2-4t-32)

0 = -3(t^2-4t-32)

Divide through by -3

(t^2-4t-32) = 0

Factorize

t²+8t-4t-32 = 0

t(t+8)-4(t+8) = 0

(t-4)(t+8) = 0

t-4 = 0 and t+8 = 0

t = 4 and t = -8

Time can't be negative:

t = 4minutes

Hence it took the drone 4 minutes take off to land on the ground

Answer: 1) h(t)= -3 (t-8) (t+4)

2) 8 mins.

Step-by-step explanation: This is the correct answer. I tried.

Answer:

Without changing the sample size the change of CI may affect the results

Step-by-step explanation:

According to Central Limit theorem the sampling distribution is given by

Z= x`- u/ σ/√n

Z has in the limit a standard normal distribution and

x`= u ± zσ/√n

From the above

x`- z∝(σ/√n) ≤ u ≤ x`+ z∝(σ/√n)

This formula is used for the confidence interval  with normal population and unknown standard deviation.

But if the different values of Z∝ are used the results will be different.

If the CI of 99% or 95% or 90% is used the values of acceptance and rejection regions change and therefore the results will change.

The value of Z∝ for

∝= 0.1 is ± 1.645

∝= 0.05 is ± 1.96

∝= 0.01 is ± 2.58

Suppose we get the calculated Z value equal 2.59 but we decrease the CI from 0.05 to 0.01 the acceptance region would become rejection region  and the level of confidence will change.

Have A Blessed Day!

The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, by what we should divide to the give expression to get 25%, 50% and 10%

Converting the percentage into fractions,

To change the percentage to a fraction, put the percentage number in the numerator and 100 in the denominator.

50% = 50/100 = 1/2, so we will divide it by 2,

25% = 25/100 = 1/4, so we will divide it by 4,

10% = 10/100 = 1/10, so we will divide it by 10.

Hence, The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.

Answer:

x ≈ 24.4

Step-by-step explanation:

Since the 2 legs of the triangle are congruent, both 26, then the triangle is isosceles.

The line segment x is a perpendicular bisector and divides the isosceles triangle into 2 congruent right triangles, with base 18 ÷ 2 = 9

Using Pythagoras' identity in either of the 2 right triangles, then

x² + 9² = 26² , that is

x² + 81 = 676 ( subtract 81 from both sides )

x² = 595 ( take the square root of both sides )

x = [tex]\sqrt{595}[/tex] ≈ 24.4 ( to the nearest tenth )
