Answer: The diagonal length of the suitcase is 30 inches. Assuming that the length and height of the suitcase form a right angle (90 degree angle), you can use the Pythagorean Theorem ( a2+b2 = c2) to solve this problem. The diagonal length is equal to the square root of the sum of the length squared and the height squared.
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
if you think about a rectangle cut by its diagonal then yoou can see that its just 2 right triangles and youre looking for the long end
Using pythagorean theorem you put in the numbers
[tex]24^{2} + 18^2 = c^2[/tex]
solving gives you
[tex]900 = c^2[/tex]
[tex]\sqrt{900} = c[/tex]
30 = c

The Kamp family has twins, Rob and Rachel. Both Rob and Rachel graduated from college 2 years ago, and each is now earning $50,000 per year. Rob is an engineer. The mean salary for engineers with less than 5 years’ experience is $60,000 with a standard deviation of $5,000. Rachel works in the retail industry, where the mean salary for executives with less than 5 years’ experience is $35,000 with a standard deviation of $8,000.
Answers
Answer:
$38,000 is correct
Step-by-step explanation:
just took it
The z value is 1.875.
To compare Rob's salary as an engineer to the mean salary for engineers with less than 5 years of experience, we need to find the z-score of Rob's salary.
The z-score formula is
z = (x - μ) / σ,
where x is the given value,
μ is the mean, and
σ is the standard deviation.
Plugging in the values, we get z = (50,000 - 60,000) / 5,000 = -2.
For Rachel's salary as an executive in the retail industry, we use the same process.
The z-score formula is z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation.
Plugging in the values, we get z = (50,000 - 35,000) / 8,000 = 1.875.

Use the given qualitative data to construct the relative frequency distribution. The 2545 people aboard a ship that sank include 406 male survivors, 1651 males who died, 362 female survivors, and 126 females who died.Complete the relative frequency distribution below. Relative Frequency Category Male survivors % Males who died % Female survivors % Females who died % (Round to one decimal place as needed.)
Answers
Answer:
The data that we have is:
total people: 2545
male survivors: 406
male who died: 1651
total males: 406 + 1651 = 2057
female survivors: 362
female who died: 126
total females: 362 + 126 = 488.
We want to know:
for the percentages, we must calculate the quotient between the total numbers of the set, and the number in the particular category we are looking for.
% male survivors = (number of male survivors/total number of males)*100%.
= (406/2057)*100% = 19.73%
% male who died = (1651/2057)*100% = 80.2%
% female survivors = (362/488)*100% = 74.18%
% female who died = (126/488)*100% = 25.82%

The converse of the parallelogram side theorem states, If the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
To prove this statement, we will assume that the opposite sides of a quadrilateral are congruent and demonstrate that it must be a parallelogram.
If both the opposite sides are parallel then we can easily prove that a parallelogram
Given: Quadrilateral PQRS, where PQ is congruent to RS and PR is congruent to QS.
To prove: PQRS is a parallelogram.
Proof:
Since PQ is congruent to RS (given), the segment PQ is parallel to the segment RS by the converse of the corresponding sides of congruent triangles are congruent (CPCTC). Since PR is congruent to QS (given), the segment PR is parallel to the segment QS by CPCTC.
Now we have both pairs of opposite sides of PQRS parallel, which satisfies the definition of a parallelogram.
Therefore, by proving that both pairs of opposite sides are PQRS parallel, we have shown that if the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
This completes the proof of the converse of the parallelogram side theorem.

The price of a watch was increased by 10% to £660. What was the price before the increase?
Answers
Answer:
£600
Step-by-step explanation:
First take if 110% equals to £660 what about 100%
100×660 =66000 ÷ 110 =£600
The original price of the watch, before the 10% increase, was £600.
Explanation:The price of a watch was increased by 10% to £660, and we are asked to find the price before the increase. We can solve this problem by considering that the increased price is 110% of the original price. To calculate the original price, let's set up the equation:
660 = 1.10 * Original Price
To solve for the Original Price, we divide 660 by 1.10:
Original Price = £660 / 1.10
This gives us the original price of the watch which is £600.

The inverse of the function y = 6ˣ is y = log₆(x), which means option A is correct.
To find the inverse of the function y = 6ˣ, we need to swap the roles of x and y and then solve for y. The steps to find the inverse are as follows:
Start with the original function: y = 6ˣ
Swap x and y:
[tex]x = 6^{y}[/tex]
To solve for y, take the logarithm of both sides using the same base (in this case, base 6):
log₆x = log₆([tex]6^{y}[/tex])
Since [tex]log_{b} (b^{y} )[/tex] = y, we get: y = log₆x
Therefore, the inverse function is y = log₆x.

There are two peice pf gold and silver alloy. The ratio between the gold and silver in the first piece is 2:3, in the second peice 3:7. If we want to have 8 gram of gold and silver alloy with gold-silver ratio 5:11 how much of each peice of alloy is needed.
Answers
Answer:
1 grams of one of the alloy; and 7 grams of the other corresponding alloy.Step-by-step explanation:
The ratio between the gold and silver in the first piece = 2:3
The ratio between the gold and silver in the second piece =3:7
The ratio in the mixture = 5:11
We want to have 8 gram of the new mixture.
Let the gram of alloy taken from the first piece=x
Therefore: gram of alloy would be taken from the second piece=(8-x)
This gives:
[tex]\dfrac{2}{5}x+ \dfrac{3}{10}(8-x)=\dfrac{5}{16}*8[/tex]
We simplify the equation above for the value of x.
[tex]\dfrac{2x}{5}+ \dfrac{3(8-x)}{10}=\dfrac{5}{2} \\\dfrac{4x+24-3x}{10}=\dfrac{5}{2}\\\dfrac{x+24}{10}=\dfrac{5}{2}\\2x+48=50\\2x=50-48\\2x=2\\x=1[/tex]
Therefore to create 8 gram of gold and silver alloy with gold-silver ratio 5:11, we take 1 grams of one of the alloy and 7 grams of the other alloy.

In 2002, a reproductive clinic reported 41 live births to 152 women under the age of 38, but only 4 live births for 86 clients aged 38 and older. Is there evidence of a difference in the effectiveness of the clinic's methods for older women? Complete parts a through c. Use alphaequals0.05.
Answers
Answer:
Difference is (0.181671, 0.263529)
We are more than 95% confident that the true percentage of life births for women under 38 years of age is between 18.17% and 26.35% higher than the true population of live births of women aged 38 or older.
Step-by-step explanation:
We are given;
x1 = 41
n1 = 152
x2 = 4
n2 = 86
Thus,
Sample proportion 1; p'1 = 41/152 = 0.2697
Sample proportion 2; p'2 = 4/85 = 0.0471
For confidence level, 1 - α = 1 - 0.05 = 0.95, using the z-table i attached under the column of z_α/2,we have
z_α/2 = 0.96
The end points of the confidence intervals for p1 - p2 are;
(p'1 - p'2) - z_α/2√[(p'1(1 - p'1)/n1) + (p'2(1 - p'2)/n2)
And
(p'1 - p'2) + z_α/2√[(p'1(1 - p'1)/n1) + (p'2(1 - p'2)/n2)
The first one is calculated as;
(0.2697 - 0.0471) - 0.96√[(0.2697(1 - 0.2697)/152) + (0.0471(1 - 0.0471)/86)
.= 0.2226 - 0.040929 = 0.181671
The second one is calculated as;
(0.2697 - 0.0471) + 0.96√[(0.2697(1 - 0.2697)/152) + (0.0471(1 - 0.0471)/86)
.= 0.2226 + 0.040929 = 0.263529
Thus, we are more than 95% confident that the true percentage of life births for women under 38 years of age is between 18.17% and 26.35% higher than the true population of live births of women aged 38 or older.

Basically, interquartile range represents the width or "dispersion" of the set. [1] The interquartile range is determined by the difference between the top quartile (25% highest) and lower quartile (25% lowest) point of the data set.
From the picture, we can find that:
The interquartile range of the bus drivers is: 20 -10 = 10 The interquartile range of the teachers is: 30 -15 = 15So the interquartile range of the distances for the bus drivers is 5 miles less than the interquartile range of the distances for the teachers.

What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
It is given that, Sophia factored 81y⁶ as (9y³)(9y²) and Ahmed factored 81y⁶ as (3y⁶)(27y).
We have to find the correct factored form,
