Answer:

small box costs $11, large box costs $13

Step-by-step explanation:

2S + 3L = 61

3S + 3L = 72

Eliminate the L terms: subtract first equation from second equation

2S + 3L = 61

-3S - 3L = -72

-------------------

-S = -11

S = 11

2S + 3L = 61

2(11)+3L  = 61

3L = 39

L = 13

small box costs $11, large box costs $13

Answer:

4.875?

convert it into an improper fraction

4 7/8 in decimal form is equal to 4.875.

To convert the mixed number 4 7/8 into decimal form, we need to add the whole number part to the fraction part.

The whole number part is 4.

To convert the fraction 7/8 into decimal form, divide the numerator (7) by the denominator (8):

= 7 ÷ 8

= 0.875

Now, add the decimal result to the whole number:

= 4 + 0.875

= 4.875

Therefore, 4 7/8 in decimal form is equal to 4.875.

Answer:

d. t-test for means

Step-by-step explanation:

Options are "a. z-test for proportions, b. z-test for means, c. none of the other three answers, d. t-test for means"

Sample size = n = 120

Sample mean = x = 0.8

Sample standard deviation = s = 2

Claim: A particular diet helps loss weight.

Hypothesis test

The null and alternative hypothesis is

H0 : μ = 0

Ha : μ < 0

Now, when population standard deviation is unknown we use t-test otherwise use z-test. So, the kind of hypothesis testing that we use is t-test for means.

Answer:

At least 75% of these commuting times are between 30 and 110 minutes

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

In this question:

Mean of 70 minutes, standard deviation of 20 minutes.

Since nothing is known about the distribution, we use Chebyshev's Theorem.

What percentage of these commuting times are between 30 and 110 minutes

30 = 70 - 2*20

110 = 70 + 2*20

THis means that 30 and 110 minutes is within 2 standard deviations of the mean, which means that at least 75% of these commuting times are between 30 and 110 minutes

Answer:

: c2 = a2 + b2 - 2ab cos C

c²=20²+15²-2×15×20×cos50

c²=400+225-600×0.64

c²=241

c=√241=15.5ft

The value of c for the given triangle can be obtained as 239.3 ft.

The cosine law for a triangle is derived from the parallelogram law of addition for two vectors.

It is given as for a triangle having sides a, b and c, the cos of the angle between sides a and b is given by,

cos(x) = (a^(2) + b^(2) - c^(2)) / (2 × a × b).

For the given diagram of a triangle, law of cosines can be applied as,

c² = a² + b² - 2abCos C

Substitute a = 15, b = 20 and ∠C = 50° to obtain,

c² = 15² + 20² - 2 × 15 × 20Cos C

c² = 625 - 600Cos(50°)

⇒ c = 239.3

Hence, the length of the other side of the triangle can be obtained as  239.3 ft.

Step-by-step explanation:

5 1/2 = 5.5 Days in a week

7 3/4 = 7.75 hr. Per Day

Total hours in a week = 5.5 × 7.75 = 42.625 hr in a week

In 10 weeks = 42.625 × 10 = 426.25 hr.

Answer:

3.5?

Step-by-step explanation:

The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.

It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,

Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]

The graph shows the voltage in a circuit changing as temperature increases from 100° to 600°.

We know that v = 1750 at t = 600° and v = 0 at t = 100°. Then the Average rate of change is given as,

Average rate = (1750 - 0) / (600 - 100)

Average rate = 1750 / 500

Average rate = 3.5

The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.

Answer:

80 degrees

Step-by-step explanation:

The total angle measure of a triangle, no matter the type, is always 180 degrees.

Using this, we can calculate the missing angle:

[tex]180=65+35+x[/tex]

[tex]x=180-(65+35)[/tex]

[tex]x=180-100[/tex]

[tex]x=80[/tex]

The measure of angle x in the triangle is 80 degrees.

The figure in the image is a triangle.

From the diagram:

Angle 1 = x

Angle 2 = 65 degrees

Angle 3 = 35 degrees

To solve for the measure of angle x, we use the fact the the sum of the interior angle of a triangle equals 180 degrees.

Hence:

Angle 1 + Angle 2 + Angle 3 = 180

Plug in the values:

x + 65 + 35 = 180

Collect and add like terms:

x + 100 = 180

Subtract 100 from both sides:

x + 100 - 100 = 180 - 100

x = 180 - 100

x = 80°

Therefore, angle x has a measure of 80 degrees.

Answer:

The area after 6 years is [tex]1519.49km^2[/tex]

Step-by-step explanation:

Given

[tex]a = 2100[/tex] --- Initial Value

[tex]r = 5.25\%[/tex] --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

[tex]y = a*(1 - r)^t[/tex]

Here

[tex]t = 6[/tex]

So, we have:

[tex]y = 2100*(1 - 5.25\%)^6[/tex]

Convert percentage to decimal

[tex]y = 2100*(1 - 0.0525)^6[/tex]

[tex]y = 2100*(0.9475)^6[/tex]

[tex]y = 1519.47866516[/tex]

[tex]y = 1519.49[/tex] -- approximated

The area after 6 years is [tex]1519.49km^2[/tex]

Given

Area = 212in²

Substitute

212 = πr²

r² = 212/3.14

r² = 67.52

r = √67.52

r = 8.22in
