Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
We know that sum of interior angles of a triangle is 180°, so;
(60) + (60) + (8x - 60) = 180
120 + 8x - 60 = 180
60 + 8x = 180
8x = 120
x = 15

Use elimination to solve the system below:
4x – 3y = 22
2x – y = 10
Answers
Answer:
Y = -2, X = 4
Step-by-step explanation:
When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.
4x-3y = 22
(2x-y = 10)-2 = -4x + 2y = -20
When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation
2x - (-2) = 10
2x +2 = 10
2x = 8
Divide both sides by 2 to get x = 4.
Steve and Bill had a very successful day fishing for speckled trout. Together they caught 46 trout in one morning. Steve was proud that he caught 14 more fish than Bill.
How many speckled trout did each person catch?
Answers
Answer:
Number of trout caught by Bill = 16 trout
Number of trout caught by Steve = 30 trout
Step-by-step explanation:
Given:
Total number of trout caught = 46
Number of trout caught by Steve = Number of trout caught by Bill + 14
Find:
Number of trout caught by Steve
Number of trout caught by Bill
Computation:
Assume;
Number of trout caught by Bill = a
Number of trout caught by Steve = a + 14
So,
Number of trout caught by Steve + Number of trout caught by Bill = Total number of trout caught
a + a + 14 = 46
2a = 46 - 14
2a = 32
a = 16
Number of trout caught by Bill = 16 trout
Number of trout caught by Steve = a + 14
Number of trout caught by Steve = 16 + 14
Number of trout caught by Steve = 30 trout

Answers
Answer:
12
Step-by-step explanation:
We can try and get both sides to have a common denominator. If we multiply the left side by 4, we get 12/16=x/16. Here, it is clear that x=12.
Answer:
x is equal to 12/16
Step-by-step explanation:
If you divide 12/16 by 4 you will realize that it is equal to 3/4. Therefore x is equal to 12. That is a really explanation, but hope it helps!

13. Randomly selected nonfatal occupational injuries and illnesses are categorized according to the day of week that they first occurred, and the results are listed below. Use a .05 significance level and that such injuries and illnesses occur with equal frequency on the weekend. State the null and alternative hypotheses, the pvalue, and conclusion. Day Fri Sat Sun Number 21 19 10
Answers
Answer:
Part A
The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend
The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend
Part B
P-value from;
Tables, 0.1 < P([tex]\chi^2[/tex] < 4.12) < 0.9
Chi-square calculator, P([tex]\chi^2[/tex] < 4.12) = 0.87
Step-by-step explanation:
The given data is presented as follows;
[tex]\begin{array}{ccc}Day&&Number\\Fri&&21\\Sat&&19\\Sun&&10\end{array}[/tex]
The significance level, α = 0.05
Part A
The hypothesis is to test that the given injuries and illnesses occur with equal frequency of the weekend
The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend
The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend
Let the expected frequency, each day of the weekend = (21 + 19 + 10)/3 = 50/3 = 16.[tex]\overline 6[/tex]
We get;
[tex]\begin{array}{ccc}Day & Observed \ Number& Expected \ Number \\Fri&21& 16.\overline 6\\Sat&19&16.\overline 6\\Sun&10&16.\overline 6\end{array}[/tex]
The chi-square test statistics
[tex]\chi^2[/tex] = (21 - 50/3)²/(50/3) + (19 - 50/3)²/(50/3) + (10 - 50/3)²/(50/3) = 4.12
The [tex]\chi^2_u[/tex] with (3 - 1) = 2 degrees of freedom = 5.991
The decision rule, [tex]\chi^2[/tex] > 5.991, we reject the null hypothesis
Given that we have [tex]\chi^2[/tex] = 4.12 < 5.991, we fail to reject H₀, therefore, there is not enough statistical evidence to suggest that the meal plan are related at α = 0.05
Part B
From the chi-square table, we have the p-value at 2 degrees of freedom for the test statistic of 4.12 is between 0.9 and 0.1
Using the chi-square calculator, we have;
P([tex]\chi^2[/tex] < 4.12) = 0.87.

A letter is randomly chosen from the word EXCELLENT. Write each probability as a fraction, decimal, and a percent.
Answers
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. A complete question is in the form:
A letter is chosen at random from the letters of the word EXCELLENT. Find the probability that letter chosen is i) a vowel ii) a consonant.
Solution:
The total number of letters found in the word EXCELLENT = 9
i) The number of vowel letters found in the word EXCELLENT = {E, E, E} = 3
Hence, probability that letter chosen is a vowel = number of vowels / total number of letters = 3 / 9 = 1 / 3
probability that letter chosen is a vowel = 1/3 = 0.333 = 33.3%
ii) The number of consonant letters found in the word EXCELLENT = {X, C, L, L, N, T} = 6
Hence, probability that letter chosen is a consonant = number of consonant / total number of letters = 6 / 9 = 2 / 3
probability that letter chosen is a consonant = 2/3 = 0.667 = 66.7%

Suppose vanilla beans cost $600 per kilogram. Julie bought 9 grams of vanilla beans. Jacques bought 70 grams of vanilla beans.
How much more did Jacques pay for his vanilla beans?
Answers
Answer:
The Correct option is 36.60
Step-by-step explanation:
The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg
Julie pays=$600*0.009=$5.4
Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-$5.4) than Julie paid
Option is wrong because that was what Julie paid
Option D is wrong because that was what Jacques paid
Option B is obviously wrong
