♡ The size of a rhombus is half the longer diagonal.
The height of the ronbus is 3cm
and
the area is 21cm². Find the length of the longer
diagonal
Answer:
Step-by-step explanation:
Area = height × side
21 = 3 * side
side = 7 cm
The side of a rhombus is half the longer diagonal
longer diagonal = 2*side =2*7=14cm

A company produces millions of 1-pound packages of bacon every week. Company specifications allow for no more than 3 percent of the 1-pound packages to be underweight. To investigate compliance with the specifications, the company's quality control manager selected a random sample of 1,000 packages produced in one week and found 40 packages, or 4 percent, to be underweight. Assuming all conditions for inference are met, do the data provide convincing statistical evidence at the significance level of α= 0.05 that more than 3 percent of all the packages produced ir one week are underweight?
a. Yes, because the sample estimate of 0.04 is greater than the company specification of 0.03.
b. Yes, because the p-value of 0.032 is less than the significance level of 0.05.
c. Yes, because the p-value of 0.064 is greater than the significance level of 0.05.
d. No, because the p-value of 0.032 is less than the significance level of 0.05.
e. No, because the p-value of 0.064 is greater than the significance level of 0.05.
Answer:
We accept H₀ we don´t have enough evidence to support that more than 3 % of the packages are undeweight
Step-by-step explanation:
Sample size n = 1000
x ( defective packages found) = 40
p = 40 /1000 p = 0,04 p = 4 % then q = 0,96
np = 0,04 * 1000 and nq / 0.96 * 1000 both greater than 5
Then we can use the approximation of binomial distribution to normal distribution.
α is significance level α = 0,05
From z- table we find z(c) for α = 0,05 z(c) = 1,64
Test Hypothesis
Null Hypothesis H₀ p = 0,03
Alternative Hypothesis Hₐ p > 0,03
We can see from alternative Hypothesis that the test is a one tail test to the right of the bell shape curve of the normal distribution
To calculate z(c) = ( 0,04 - 0,03 ) / √ ( p*q)/n
z(c) = 0,01 * 31,62 / √ 0,04*0,96
z(c) = 0,3162 / 0,1959
z(c) = 1,6140 z(c) ≈ 1,61
Comparing z(s) and z(c)
z(c) > z(s) 1.64 > 1.61
Then z(s) is in the acceptance region for H₀ we accept H₀
I don’t understand how to solve this. Please explain the steps. Thanks.
Answer:
D
Step-by-step explanation:
When you are raising something to a fractional power, you are raising it to the power of the numerator and finding the root denoted by the denominator. The explanation above is kinda confusing, so here is an example:
x^(3/5)
This would be written as:
[tex]\sqrt[5]{x^3}[/tex]
Now for the actual problem. Since the numerator is 4, we start by raising x to the 4th power, x^4.
Because the denominator is 5, we find the 5th root:
[tex]\sqrt[5]{x^4}[/tex]
This matches none of the answers shown, so the answer is none of the above or D.
Answer:
D
Step-by-step explanation:
The answer would be 5 square root x^4

pythagorean theorem round to the nearest tenth
Answer:
15
Step-by-step explanation:
Using pythagoras theorem
R, S, and T represent the lengths of the three sides of a right triangle. Select the equation that represent the relationship between R, S and T. (the two's are exponents)
a. R 2+ S 2= T 2
b. R 2+ T 2 = S 2
c. R 2 + R 2= S 2
d. T 2 + S 2= R 2
e. T 2- S 2= R 2
Answer:
a. R 2+ S 2= T 2
Step-by-step explanation:
Is this multiple choice? If not, then I will explain my answer.
I would say that it is R² + S² = T² because, the original pythagorean theorem equation is a² + b² = c².
They are put in an alphabetical order, a, b, c.
R goes first in the alphabet, then S and T. So, that's why I say it is:
R² + S² = T²

Step-by-step explanation:
Find the product of
(−9−11i) and its conjugate.
Answer:
202
Step-by-step explanation:
First, we can find the conjugate of (-9 -11i)
Given a complex number a + bi, the conjugate would be a - bi.
So, the conjugate of -9 -11i is -9 + 11i.
Now, we multiply!
(-9-11i)(-9+11i)
This resembles the special product (a+b)(a-b) which multiplies out to a^2 - b^2
To apply this we subtract the square of the second number from the first.
(-9)^2 - (11i)^2
81 - 121i^2
i^2 is -1, so we can substitute it in:
81 + 121 = 202

Find the median of each data set.
Median of seventh grade=
Median of ninth grader
Answer:
median of seventh grade = 16.5
median of ninth grade = 16.5
Step-by-step explanation:
median = middle number, there are 18 numbers in total of each set. Since its even the middle number is kinda 16 and 17, but you can only choose one so the middle of 16 and 17 is 16.5

The manager of a restaurant tracks the types of dinners that customers order from the menu correct amount of food is ordered from the supplier each week. Data from customer orders last weekly distribution.
Type of Dinner Beef Chicken Fish Pork Vegetarain
Propotion 0.18 0.41 0.15 0.20 0.06
The manager believes that there might be a change in the distribution from last year to this year. A random sample of200 orders was taken from all customer orders placed last week. The following table shows the results of the sample.
Type of Dinner Beef Chicken Fish Pork Vegetarain

Assume each order is independent. For which type of dinner is the value of its contribution to the appropriate test statistic the greatest?
a. beef
b. chicken
c. fish
d. pork
e. vegetarian
Answer:
The answer is "Option E".
Step-by-step explanation:
In order to find the contribution needed, we must use Chi-Square test statistics here.
Chi-square [tex]= \Sigma [\frac{(O -E)^2}{E}][/tex]
Here frequencies O are observed or frequencies E are expected.
Please find the calculation in the attached table.
Hence the contribution Chi-square is the highest for the vegetarian.
The value of its contribution to the appropriate test statistic the greatest is Vegetarian. The correct option is E.
