alex, bella, cara share £90; work how much each of them have if:
alex has £x
bella has 3 times as much as alex
cara has £10 less than alex

Answers

Step-by-step explanation:

given,

alex = x

bella = 3x

cara = x - 10

and also given,

[tex]x + 3x + (x - 10) = 90 \\ x + 3x + x - 10 = 90 \\ 5x - 10 = 90 \\ 5x = 90 + 10 \\ 5x = 100 \\ x = 100 \div 5 \\ = 20[/tex]

Given x = £20,

Alex = £x = £20

Bella = £3x = £3x20 = £60

Cara = £(x-10) =£(20-10) =£10

A sample of male high school athletes was selected and the resulting value of the chi-square test statistic was 10.65. Which if the following represents the p value

Answers

Answer:

[tex]P(x^{2} \geq 10.65) = 0.03\\[/tex]

Step-by-step explanation:

Since there are 5 categories, there are 5−1=4 degrees of freedom. The probability of obtaining a chi-square test statistic greater than or equal to 10.65 with 4 degrees of freedom is approximately 0.03, as found using technology.

find the area of the polygon to the nearest square inch

Answers

9514 1404 393

Answer:

120 square inches

Step-by-step explanation:

The formula for the area is ...

A = (1/2)Pa

where P is the perimeter and 'a' is the apothem. The perimeter of this octagon is 8 times the side length.

A = (1/2)(8×5 in)(6 in) = 120 in²

The area of the octagon is 120 square inches.

Miles takes a 350-mile round-trip flight to visit his parents. To qualify for Gold status at Awesome
Airlines, one must fly at least 7700 and less than 12600 miles each year. How many times would Miles
need to visit his parents each year to attain Gold status? Express your answer in interval notation.

Answers

Answer:

Miles must travel a minimum of 22 times and a maximum of 36 times to achieve Gold status.

Step-by-step explanation:

Given that Miles takes a 350-mile round-trip flight to visit his parents, and to qualify for Gold status at Awesome Airlines, one must fly at least 7700 and less than 12600 miles each year, to determine how many times would Miles need to visit his parents each year to attain Gold status, the following calculation must be performed:

7700/350 = X

22 = X

12600/350 = X

36 = X

Thus, Miles must travel a minimum of 22 times and a maximum of 36 times to achieve Gold status.

d(x³+4x)/dx find the derivative ?

Answers

Answer:

3x²+4

Step-by-step explanation:

To find the derivative of something with respect to x, for each term multiply the power on the x in that term by the coefficient in the same term, and then lower the x's power by one.

For example, if we had to find the derivative of 2x³, we would first multiply the power on the x (3) by the coefficient (2): 6x³. Then lower the x's power by one: 6x². So the derivative of 2x³ is 6x².

To find the derivative an expression with several terms added together, you just do the same for each terms.

d(x³+4x)/dx

= [tex]\frac{d}{dx}[/tex] x³+4x

= 3x²+4

Option C

Step-by-step explanation:

The two triangles will be similar if the ratio of their corresponding sides are proportional. Let's check this ,

1st side :-

= 8:3

2nd side :-

= 10 : 4 = 5:2

3rd side :-

= 6:5 .

Since the ratio of the sides of triangle are not same therefore that 2 triangles are not similar .

Option C is correct .

If the perimeter of the triangle is 95 inches, what is the length of each side? n, 3n+8, and 4n+7.

Answers

Answer:

10, 38, 47

Step-by-step explanation:

The perimeter is the sum of the side lengths:

95 = n +(3n +8) +(4n +7)

80 = 8n . . . . . . subtract 15

10 = n

3n+8 = 3(10) +8 = 38

4n+7 = 4(10) +7 = 47

The lengths of the sides of the triangle are 10, 38, 47.

Answer:

yes

Step-by-step explanation:

the ratio of 28 : 36 can be simplifeid by dividing both sides of the ratio by 4.

28/4=7

36/4=9

so the ratio of 28 : 36 is equal to 7 : 9

A major credit card company is interested in whether there is a linear relationship between its internal rating of a customer’s credit risk and that of an independent rating agency. Thecompany collected a random sample of 200 customers and used the data to test the claim that there is a linear relationship. The following hypotheses were used to test the claim.
The test yielded a t -value of 3.34 with a corresponding p -value of 0.001. Which of the following is the correct interpretation of the -value?
a. If the alternative hypothesis is true, the probability of observing a test statistic of 3.34 or greater is 0.001.
b. If the null hypothesis is true, the probability of observing a test statistic at least as extreme as 3.34 is 0.001.
c. If the null hypothesis is true, the probability of observing a test statistic of 3.34 or greater is 0.001This answer is incorrect.
d. If the alternative hypothesis is true, the probability of observing a test statistic at least as extreme as 3.34 is 0.001.
e. If the null hypothesis is true, the probability of observing a test statistic of 3.34 is 0.001.

Answers

Answer:

Step-by-step explanation:

The test produced, a t-value of 3.34 and a p-value of 0.001 as a result. The possibility of seeing a test statistic at least as extreme as 3.34 is 0.001; the proper reading of the p-value is different if the alternative hypothesis is true.

Probability calculation:

p-value = 0.001

t = 3.34

Whether the alternative theory is true because there is a 0.001, and the possibility of showing testing statistics as extreme as 3.34.The p-value indicates that since the Null-hypothesis is true, there is a 0.001 chance of seeing a test statistic at least as extreme as 3.34.

Therefore, the final answer is "Option d".

Square root 3 sin theta = -3 cos theta

Answers

Answer:

Step-by-step explanation:

hello : the equation is : √3 sinθ= -3 cosθ means :

sinθ/cosθ = -3/√3

sinθ/cosθ = - √3 because : 3 =√3 ×√3

but : sinθ/cosθ = tan θ

tan θ = - √3 and - √3 = tan( π - π/3) = tan(2 π/3)

you have : tan θ = tan(2 π/3)

note : tanx=tany means : x= y + k π ... k in Z

so : all solutions in R are θ = 2 π/3+k π ... k in Z
