Answer:

12 square units

Step-by-step explanation:

The area of a given figure is the measure of space occupied by the figure on a 2 dimensional plane.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

From the given grid, the following can be observed for triangle STU.

base SU = 6 units

height = 4 units

Thus,

area of triangle STU =  [tex]\frac{1}{2}[/tex] x base x height

                                  =  [tex]\frac{1}{2}[/tex] x 6 x 4

                                  = 3 x 4

area of triangle STU = 12 square units

The required area of triangle STU is 12 square units.

Answer:

160°

Step-by-step explanation:

Quadrilateral's angles add up to 360 degrees.

So:

x = fourth angle measure (unknown currently)

50° + 72° + 78° + x = 360°

200° + x = 360°

x = 160°

Answer:

72

Step-by-step explanation:

Since 203% is 2.03 in decimal form we can write an equation that looks like:

2.03x=146.16 (divide both sides by 2.03)

x=72

Answer:

72

Step-by-step explanation:

Call the unknown number (x), set up a proportion to model the situation;

[tex]\frac{value}{unknown}=\frac{percent}{100}[/tex]

Substitute

[tex]\frac{146.16}{x}=\frac{203}{100}[/tex]

Cross products,

[tex](146.16)(100)=(203)(x)\\\\14616=203x\\[/tex]

Inverse operations,

[tex]14616=203x\\/203\\\\72 = x[/tex]

Answer:

672 m^3

Step-by-step explanation:

The formula to find the volume of a prism is V = l x w x h, where l is length, w is width, and h is height. You are given the length, width, and height in the problem so you just plug it into the formula.

V = 8 x 6 x 14

After multiplying all three numbers together, you should get the answer 672 m^3.

Answer:

Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages

Step-by-step explanation:

Let x represent the number of messages that Keiko sent.

Since Dale sent 7 less than Keiko, his number can be represented by x - 7

Since Tony sent 4 times as many as Keiko, his number can be represented by 4x

Using these variables, create an equation:

(x) + (x - 7) + (4x) = 95

Add like terms and solve for x:

6x - 7 = 95

6x = 102

x = 17

So, Keiko sent 17 messages.

Subtract 7 from this to find how many Dale sent:

17 - 7

= 10

Multiply it by 4 to find how many Tony sent:

17(4)

= 68

So, Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages

[tex]x\\[/tex] ± [tex]\frac{s}{\sqrt{n}}[/tex] = [tex]9.78[/tex] ± [tex]\frac{10.45}{\sqrt{60}}[/tex]

Step-by-step explanation:

x is the value of our population/sample mean. Given that it's 98.75, we substitute x for 98.75.

We follow this pattern for s and n, which are the standard deviation and sample size respectively, to fill out the rest of our equation. This means that s is 10.45 and n is 60

Since we know the formula is [tex]x\\[/tex] ± [tex]\frac{s}{\sqrt{n}}[/tex], we can input our new values.

This gives us our answer of [tex]9.78[/tex] ± [tex]\frac{10.45}{\sqrt{60}}[/tex]

TL;DR

I took the test and the answer was right

The interval in which the population mean $98.75 with standard deviation of $10.45 with a sample size of 60 is given by its lower and upper limit as given by: 98.75 ± 10.45/(√(60))

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) \approx 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) \approx 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) \approx 99.7\%[/tex]

where we had  where mean of distribution of X is [tex]\mu[/tex]  and standard deviation from mean of distribution of X is [tex]\sigma[/tex] (assuming X is normally distributed).

Suppose X has has a distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], then, the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with mean equal to the mean of X, and standard deviation equal to [tex]\sigma/\sqrt{n}[/tex]

Symbolically, we write it as:

[tex]X \sim N(\mu, \sigma) \implies \overline{X} \sim N(\mu,\sigma/\sqrt{n} )[/tex]

(for large enough samples, n > 30)

For this case, we're specified that:

Then, the distribution of the sample mean is approximately normal distribution with mean $98.75 and standard deviation approximately [tex]10.45/\sqrt{60}[/tex]

Symbolically, we get:

[tex]X \sim N(98.75, 10.45/\sqrt{60})[/tex]

Then, using empirical rule, we find the limits for sample mean for which we're 68% sure that the sample mean will lie in that interval as one standard deviation (of the sample mean) away from its mean.

[tex]P\left( 98.75 - 10.45/\sqrt{60} < \overline{X} < 98.75 + 10.45/\sqrt{60}\right) \approx 68\%[/tex]

So, limits are:

[tex]98.75 \pm \dfrac{10.45}{\sqrt{60}}[/tex]

Thus, the interval in which the population mean $98.75 with standard deviation of $10.45 with a sample size of 60 is given by its lower and upper limit as given by: 98.75 ± 10.45/(√(60))

==============================================================

Work Shown:

I'm assuming you meant to write [tex]f(x) = 2^{x+4}[/tex] where all of the "x+4" is the exponent.

If we shift f(x) 5 units to the right to end up with g(x), then,

[tex]g(x) = f(x-5)\\\\g(x) = 2^{x-5+4}\\\\g(x) = 2^{x-1}\\\\[/tex]

In the second step, I replaced every copy of x with x-5 so that I could apply the translation of 5 units to the right.

The exponent for g(x) is x-1, which matches up with x-k. We see that k = 1.

Answer: 24

Step-by-step explanation: so you calculate everything in the parenthesis fist so you do (5-1+3) to (4+3)  then you do (4+3=7)

so this is how your equation is going to look 10+4÷2×7 then your going to do 4 divied by 2=2 then your going to do 2*7=14 and 14+10=24

STEP ONE- 10+4÷2(4+3)

STEP TWO- 10+4÷2×7

STEP THREE-10+2×7

STEP FOUR-10+14

Answer:

D. 18

Step-by-step explanation:

The polygon given is a 5-sided polygon (pentagon). Sum of all interior angles of a 5-sided polygon = (n - 2) * 180°

= (5 - 2) * 180 = 540°

Therefore:

95° + (7x - 4)° + (3x + 23)° + (9x - 6)° + 90° = 540°

Solve for x

95 + 7x - 4 + 3x + 23 + 9x - 6 + 90 = 540

Add like terms

198 + 19x = 540

19x = 540 - 198

19x = 342

x = 342/19

x = 18

Answer:

lewis has $179 more than mary

Lewis has the greater total amount of money than Mary by $879

Given the following data:

To determine who has the greater total amount of money and by how much greater is it:

Mathematically, simple interest is given by the formula:

[tex]S.I = PRT[/tex]

Where:

[tex]S.I = 3700 \times 0.032 \times 15[/tex]

S.I = $1,776

[tex]S.I = 3000 \times 0.059 \times 15[/tex]

S.I = $2,655

Therefore, Lewis has the greater total amount of money.

Next, we would find the difference in their simple interest:

[tex]Difference = 2655-1776[/tex]

Difference = $879

Answer: See explanation

Step-by-step explanation:

The sampling methods include:

1. Simple random sampling: Here, the individuals in the population have an equal chance of being selected as the selection is done randomly and anyone can be picked from the population

2. Systematic sampling: This is when the selection of the individuals is done at regular intervals. For example from the population, every 10th person might be picked.

3. Stratified sampling: Here, the total population is first divided into a smaller group called the strata before the sampling is done.

4. Clustered sampling: Here, the sampling unit is the subgroups of the population and not the individuals.
