Answer: x = 8,-2
Step-by-step explanation:
x^2-6x-16=0
x =[ -(-6)+-sqrt(-6)^2 - 4x1x(-16)/2x1
x = [6+-sqrt 36+64]/2
x = 6+-sqrt 100/2
x = 6 +-10/2
x = 6+10/2, 6-10,2
x = 8, -2
Answer:
Step-by-step explanation:
This is the quadratic equation formula for the roots.
x^2 - 6x - 16 = 0
x = [- (-6) +/- √( (-6)^2 - 4*1*-16) / 2*1
x = (6 +/- √(36 + 64) / 2
x = (6 +/- √(100) / 2
x = (6 +/- 10) / 2
x = 16/2 = 8
x = -4/2 = -2

Members of a softball team raised $1513.50 to go to a tournament. They rented a bus for $961.50 and budgeted $46 per player for meals. Write and solve an equation which can be used to determine xx, the number of players the team can bring to the tournament.
Answers
Answer: 1513.50=961.50+46x
The number of players the team can bring to the tournament = 12.
Step-by-step explanation:
Let x= the number of players the team can bring to the tournament.
Total money raised = Rent of bus + (Cost per player) (Number of players)
\(1513.50=961.50+46x\\\\\Rightarrow\ 46x=1513.50-961.50\\\\\Rightarrow\ 46x = 552\\\\\Rightarrow x=\dfrac{552}{46}\\\\\Rightarrow x=12\)
Hence, the number of players the team can bring to the tournament = 12.

The period of the sine wave is 20 s
What is the period of a sine wave?The period of a sine wave is the time it takes the wave to complete one cycle of oscillation
To determine the period of the wave, we prceed as follows.
The period of the wave, T is the time interval between two consecutive maximum points of the wave.
So, from the graph, the first maximum point is at t = 1 s.
Also, the next maximum point is at t' = 21 s
So, the period , T = t' - t
= 21 s - 1 s
= 20 s
So, the period is 20 s

Answers
To arrange the districts in a way that is most advantageous to Gray, we want to create districts where Gray has a majority of the votes. Since there are 90 census tracts, we can divide them into 10 districts with 9 seats each.
To maximize Gray's chances of winning, we can allocate the census tracts in the following way:
District 1: Assign 9 gray-voting census tracts.
District 2: Assign 9 gray-voting census tracts.
District 3: Assign 9 gray-voting census tracts.
District 4: Assign 9 gray-voting census tracts.
District 5: Assign 9 gray-voting census tracts.
District 6: Assign 9 gray-voting census tracts.
District 7: Assign 5 gray-voting census tracts and 4 white-voting census tracts.
District 8: Assign 5 gray-voting census tracts and 4 white-voting census tracts.
District 9: Assign 5 gray-voting census tracts and 4 white-voting census tracts.
District 10: Assign 4 gray-voting census tracts and 5 white-voting census tracts.
By allocating the census tracts in this manner, Gray will have a majority in the first six districts, ensuring a higher likelihood of winning those districts.
Districts 7, 8, and 9 have a slight advantage towards Gray with a 5-4 split, and District 10 has a slight advantage towards White with a 5-4 split.

between 1849 and 1852, the population of __________ more than doubled.
Answers
Answer:
Step-by-step explanation:
Between 1849 and 1852, the population of California more than doubled due to the California Gold Rush.
Between 1849 and 1852, the population of California more than doubled. California saw a population boom in the mid-1800s due to the California Gold Rush, which began in 1848. Thousands of people flocked to California in search of gold, which led to a population boom in the state.What was the California Gold Rush?The California Gold Rush was a period of mass migration to California between 1848 and 1855 in search of gold. The gold discovery at Sutter's Mill in January 1848 sparked a gold rush that drew thousands of people from all over the world to California. People from all walks of life, including farmers, merchants, and even criminals, traveled to California in hopes of striking it rich. The Gold Rush led to the growth of California's economy and population, and it played a significant role in shaping the state's history.

1. An article in Nature describes an experiment to investigate the effect of consuming chocolate on cardiovascular health (Plasma Antioxidants from Chocolate, Nature, Vol. 424, 2003, pp. 1013). The experiment consisted of using three different types of chocolates: 100 g of dark chocolate, 100 g of dark chocolate with 200 mL of full-fat milk, and 200 g of milk chocolate. Twelve subjects were used, 7 women and 5 men, with an average age range of 32.2 +1 years, an average weight of 65.8 + 3.1 kg, and body-mass index of 21.9 + 0.4 kg/m2. On different days a subject consumed one of the chocolate- factor levels and one hour later the total antioxidant capacity of their blood plasma was measured in an assay. Data similar to that summarized in the article are shown in the following table. Perform an analysis of variance to see if the chocolate types have differing effects on the mean antiox- idant capacity. Show all four steps. (12 points, 3 points for showing each step. If done in jamovi, you do not need to show calculations, just report relevant information from the table.)For all hypothesis tests, you must show the four steps: 1. Hypotheses 2. Test statistic 3. p-value or p-value approximation 4. Conclusion sentence (Do no just say "Reject the null hypothesis" or "Fail to reject the null hypothesis") If doing the hypothesis test in jamovi, you must include the jamovi output but show the four steps separately as well.
Answers
The results of the Analysis of Variance (ANOVA) test indicate that the mean antioxidant capacity for the three types of chocolate is different, thus the null hypothesis is rejected and the alternative hypothesis is accepted.
The Analysis of Variance (ANOVA) test has four phases, which are as follows:
1) The three forms of chocolate's mean antioxidant capacity are either the same (null hypothesis) or different (alternative hypothesis);
2) An ANOVA is used as the test statistic;
3) The p-value is 0.000, below the threshold of 0.05, and
4) As a result, the null hypothesis is disproved and the alternative hypothesis is accepted, indicating that the three forms of chocolate have distinct average antioxidant capacities. As a result, the analysis's findings show that consuming various chocolate varieties changes the blood plasma's mean antioxidant capacity.

Answers
The two statements that are true about the company's Market share going from 50 to 65 percent of the total market . The initial market share and multiply by 100, which gives 30 percent. Option B is correct answer.
The two statements that are true about the company's market share going from 50 to 65 percent of the total market are:
The company's market share increased by 30 percent: The difference between the initial market share of 50 percent and the final market share of 65 percent is 15 percentage points. To calculate the percentage increase, we can divide the difference by the initial market share and multiply by 100, which gives (15/50) x 100 = 30 percent.
The company's relative market position improved: With a market share of 65 percent, the company now holds a greater proportion of the total market than before. This means that its relative market position has improved compared to its competitors, who have a smaller share of the market. This could translate into increased bargaining power, profitability, and other benefits for the company.
