Answer:
14.3
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
14^2 + 3^2 = c^2
196 + 9 = c^2
205 = c^2
Take the square root of each side
sqrt(205) = sqrt(c^2)
14.31782106 = c
Rounding to the nearest tenth
14.3 = c
Answer :
14.3 yd⠀
Explanation :
This is Right Angled Triangle.⠀
Solution :
We'll solve this using the Pythagorean Theorem.where,
XY (3 yd) is the perpendicularYZ (14 yd) is the Base.XZ is the Hypotenuse.We know that,
[tex]{\longrightarrow \pmb{\mathbb {\qquad (XZ) {}^{2} = (XY) {}^{2} +( YZ) {}^{2} }}} \\ \\ [/tex]
Now, we will substitute the given values in the formula :
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = (3) {}^{2} +( 14) {}^{2} }}} \\ \\ [/tex]
We know that, (3)² = 9 and (14)² = 196. So,
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = 9 +196 }}} \\ \\ [/tex]
Now, adding 9 and 196 we get :
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = 205 }}} \\ \\ [/tex]
Now, we'll take the square root of both sides to remove the square from XZ :
[tex]{\longrightarrow \sf{\pmb {\qquad \sqrt{(XZ) {}^{2}} = \sqrt{205 }}}} \\ \\ [/tex]
When we take the square root of (XZ)² , it becomes XZ,
[tex]{\longrightarrow \sf{\pmb {\qquad XZ = \sqrt{205 }}}} \\ \\ [/tex]
We know that, square root of 205 is 14.317 (approx) .
[tex]{\longrightarrow { \mathbb{\pmb {\qquad XZ }}}} \approx \pmb{\mathfrak{14.317 } }\\ \\ [/tex]
So,
The measure of the missing side (XZ) is 14.3 (Rounded to nearest tenth)Related Questions
Car insurance companies want to keep track of the average cost per claim. The current data in use for Auto Insurance R Us is an average of $2,200 for each claim with a standard deviation of $500. With this average, the company can stay competitive with rates but not lose money. However, the statistician for the company believes that the cost of the average claim has increased. He pulled 40 recent claims and found the average to be $2,350. Which most restrictive level of significance would suggest that the company should raise rates
Answers
Answer:
The answer is 5% because its correct lol
Step-by-step explanation:
The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
To determine if the increase in the average cost per claim is statistically significant, we can perform a hypothesis test.
Let's use a one-sample t-test, where:
Null hypothesis (H0): The average cost per claim is still $2,200.
Alternative hypothesis (Ha): The average cost per claim is greater than $2,200.
We can use a t-test because we have a sample mean, sample size, and population standard deviation.
The test statistic is calculated as:
t = (sample mean - hypothesized mean) / (standard deviation/√ (sample size))
Plugging in the values given, we get:
t = (2350 - 2200) / (500 / √(40))
t = 4.38
Using a t-table with degrees of freedom (df) = 39 (sample size - 1), we can find the p-value associated with this test statistic.
At the 0.01 level of significance (most restrictive level), the critical t-value is 2.704.
Since our calculated t-value is greater than the critical t-value, we reject the null hypothesis and conclude that there is evidence to suggest that the average cost per claim has increased.
Therefore,
The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Step-by-step explanation:
Formulae
Circumference of a circle = [tex]2 \pi r[/tex]Area of a circle = [tex]\pi r^2[/tex](where r is the radius of the circle)
The railing of the circular fountain is the circumference of a circle.
The area of the fountain is the area of a circle.

===============================================
Explanation:
The tangent function is being applied to some unknown angle x. To isolate x, we undo whatever tangent is doing. So we apply the inverse function. Specifically the inverse tangent function. This is also known as "arctangent" and your calculator most likely shows it as a button with a "-1" exponent above the "tan"
So apply the arctangent to both sides to get
tan(x) = 0.7773
arctan(tan(x)) = arctan(0.7773)

A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 50 pounds
and each large box of paper weighs 80 pounds. A total of 19 boxes of paper were
shipped weighing 1280 pounds altogether. Determine the number of small boxes
shipped and the number of large boxes shipped.
Answers
Answer:
x = 8
y = 11
Step-by-step explanation:
Total small box weight = 50x [x being the number of small boxes]
Total large box weight = 80y [y being the number of large boxes]
Total boxes = x+y = 19
Total weight = 1280
Determine x and y.
You know 2 equations. One for weight and another for number of boxes each.
1280 = 50x +80yx+y = 19Rewrite second equation:
x+y=19
y=19-x
You have to plug in one into another.
1280 = 50x + 80(19-x)
Solve for x
1280 = 50x + 1520 - 80x
-240 = -30x
x = 8
Solve for y by plugging in x into one of the equations:
8+y = 19
y = 11

How to subtract mixed numbers with unlike denominators?.
Answers
To subtract mixed numbers with different denominators, follow these steps:
1. Rename the fractions using a common denominator.
2. Subtract whole numbers from whole numbers. You might need to regroup first.
3. Subtract fractions from fractions.
4. Simplify, if needed.
Let's try it with [tex]2\frac{3}{5}-1\frac{1}{4}[/tex]
First, rename the fractions using a common denominator. The least common denominator of these fractions is 20. Multiply to make equivalent fractions with 20 as the denominator.
[tex]\frac{3x4}{5x4}=\frac{12}{20}[/tex] [tex]\frac{1x5}{4x5}=\frac{5}{20}[/tex]
Rewrite the problem and subtract the whole numbers.
[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{?}{?}[/tex]
Now, subtract the fractions. Subtract the numerators and keep the denominator the same.
[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{7}{20}[/tex]
