Step-by-step explanation:

-3√12-2√27-2√45

3√12=6√3

2√27=6√3

2√45=6√5

=6√3-6√3-6√5

Step-by-step explanation:

If y was directly proportional to x, the graph of y against x would pass through the origin (O).

Since the graph above does not show this, y is not directly proportional to x.

Step-by-step explanation:

(5a^2b^3)(6a^kb) = 30a^6b^4

a^2 * a*k = a^6

a^(2 + k) = a^6

2 + k = 6

k = 4

Answer: 4

The value of k from the equation is k = 4

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

( 5a²b³ ) ( 6a^k )b = 30a⁶b⁴

On simplifying , we get

From the laws of exponents , we get mᵃ×mᵇ = mᵃ⁺ᵇ

So , ( 30a^( 2 + k ) ) b⁴ = 30a⁶b⁴

Divide by 30b⁴ on both sides , we get

a^( 2 + k ) = a⁶

Now , the bases of the exponents are same ,

So , 2 + k = 6

Subtracting 4 on both sides , we get

k = 4

Therefore , the value of k = 4

Hence , the exponential equation is solved

Answer:

we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Step-by-step explanation:

We are given;

Population proportion; p = 30% = 0.3

Sample proportion; p^ = 37% = 0.37

Sample size; n = 100

Let's define the hypotheses;

Null hypothesis; H0: p ≤ 0.3

Alternative hypothesis; Ha: p > 0.3

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

Thus;

z = (0.37 - 0.3)/√(0.3(1 - 0.3)/100)

z = 0.07/0.04582575695

z = 1.53

From z-distribution table, at z=1.53 we have;

p-value = 1 - 0.9370 = 0.063

This p-value is greater than the significance level of 0.02 and thus we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Answer:

Test statistic (t) = 0.625

Step-by-step explanation:

Step(i):-

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S)  = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

Step(ii):-

Test statistic

                     [tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]

                   [tex]t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625[/tex]

Answer:

A) The amount of cereal inside a cereal box.

Hope this helps

To solve the problem we must know about the volume.

Volume is described as the total amount of space taken by an object. It is a scalar quantity and it is 3 dimensional.

The amount of cereal inside a cereal box has volume.

As we know that the cereal box has space inside to hold something therefore, the cereals or something can be put inside this that will make the space inside the box. Also, the box has length, breadth, and height, therefore, it is 3 dimensional.

Hence, the amount of cereal inside a cereal box has volume.

Answer:

Area of ABC = 16[tex]\sqrt{2}[/tex]

Step-by-step explanation:

if Area of Circle is π·r², which in this case equals 4π, then the radius is 2; this gives us the height of the triangle as 4

since it's a 60-60-60 triangle, the height perpendicular to base creates a 30-60-90 triangle, whose sides are in the ratio of 1 : √2 : 2

therefore the entire base is 4√2 + 4√2 or 8√2

A (ΔABC) = 1/2(4) · 8√2  =  16√2

Confidence interval = m ± Zcritical(s/√n)

n = sample size = 16

Zcritical at 95% = 1.96

Using calculator :

Sample mean, m = 224.0019

Standard deviation, s = 0.0618

Lower bound : 24.0019 - 1.96(0.0618/√16) = 23.971618

Upper bound : 24.0019 + 1.96(0.0618/√16) = 24.032182
