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

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:

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.

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: b=10

Step-by-step explanation:   ((0 -  8 • (b + 11)) -  4) -  (18 - 19b)  = 0

Pull out like factors :

  11b - 110  =   11 • (b - 10) 11 • (b - 10)  = 0

b-10 = 0  

Add  10  to both sides of the equation :  

                     b = 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 )

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.

Answer: The probability that: None will be defective = 0.8836

Step-by-step explanation:

Let x be the number of defectives watch.

As per given: p= 6%= 0.06 (probability of defective)

Sample size : n= 2

Binomial probability distribution formula : [tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]

P(No defective)=P(X=0)

[tex]^{2}C_0(0.06)^0(1-0.06)^{2} =(1)(0.94)^2=0.8836[/tex]

Hence, The probability that: None will be defective = 0.8836

Step-by-step explanation:

ayana is wrong

The statement given by Lean that "Ill isolate (x - 5)^2 by subtracting 4 from both sides of the equation. Then I'll solve by taking the square root." is correct way of solving an equation.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given equation can be solved as shown below,

(x- 5)² + 4 = 16

Subtract 4 from both the sides of the equation,

(x- 5)² + 4 -4 = 16 - 4

(x- 5)² = 12

Taking square root of both the sides of the equation,

√(x- 5)² = √12

x - 5 = √12

Add 5 on both the sides of the equation,

x - 5 + 5 = √12 + 5

x = √12 + 5

Now, if both Ayana and Leah process of solving is compared with the solution above, it can be concluded that Leah is using the correct method to solve the equation.

Hence, the statement given by Lean that "Ill isolate (x - 5)^2 by subtracting 4 from both sides of the equation. Then I'll solve by taking the square root." is correct way of solving an equation.
