Write the related series for the finite sequence –7, –10, –13, . . ., –22. then find the sum.–7 + (–10) + (–13) + (–16) + (–19) + (–22) = –87
–7 + (–10) + (–13) + (–15) + (–18) + (–22) = –85
–7 + (–10) + (–13) + (–14) + (–18) + (–22) = –84

Step-by-step explanation:
Given finite sequence : -7, -10, -13, . . ., -22.
Difference between first and second term=[tex]-10-(-7)=-10+7=-3[/tex]
Difference between second and third term =[tex]-13-(-10)=-13+10=-3[/tex]
Hence, the common difference = -3
The next term after -13 =[tex]-13+(-3)=-13-3=-16[/tex]
The next term after -16 =[tex]-16+(-3)=-16-3=-19[/tex]
The next term after -19 =[tex]-19+(-3)=-19-3=-22[/tex].........which is the last term of the sequence.
Now, the sum of the given sequence =[tex]-7+(-10)+ (-13) + (-16) + (-19) + (-22) [/tex]

give answer as a fraction
The solution is : 1/4 is the probability that it has your favorite type of meat on it.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, we have,
given that,
At the sandwich shop, there are four different types of meat and three different types of cheese.
If you select a sandwich without looking,
then we need to find the probability.
Solution
There are four different types of meat and three different types of cheese
Probability = number of required outcome / number of possible outcome
Total amount of meat = number of possible meat = 4
If you only have one favorite type of meat the probability 1/4
Hence, the correct answer is Option B.
The solution is : 1/4 is the probability that it has your favorite type of meat on it.

A student is attempting to calculate the square root of 18. His work is shown below. Which statement below best applies to his mathematical reasoning?
Givin sqrt 18 I observe that 18 is not a perfect square. I notice the perfect squares closest to 18 are 16 and 25, so I estimate the answer to fall somewhere between those numbers. Since 18 is closer to 16, I estimate that sqrt 18= 17
A.
18 is a perfect square, and the radical could have been evaluated directly.
B.
16 and 25 are not perfect squares, and therefore the student should not have chosen those numbers to estimate sqrt 18
C.
The student did not evaluate sqrt 16 and sqrt 25 before estimating sqrt 18
D.
The student has made no error. sqrt 18= 17
a tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an intial speed of 130 feet per second. What is the maximum height, in feet, the ball will attain? round to the nearest hundredth
Final answer:
Using the kinematic equation for vertical motion, the maximum height a tennis ball will reach when fired at an initial speed of 130 ft/s from a height of 2 feet is approximately 264.91 feet.
Explanation:
Calculating the Maximum Height of a Tennis Ball
The maximum height that a tennis ball will attain when fired vertically can be calculated using the kinematic equations that describe projectile motion. Given that the initial speed of the ball is 130 feet per second and it is launched from a height of 2 feet, we can use the equation for vertical motion:
v^2 = u^2 + 2gh
where v is the final velocity (0 ft/s at the highest point), u is the initial velocity (130 ft/s), g is the acceleration due to gravity (-32.2 ft/s^2, negative because it is directed downwards), and h is the height gained. Rearranging the formula to solve for h we get:
h = (v^2 - u^2) / (2g) = (0 - 130^2) / (2 * -32.2)
After calculating h, we add the initial launch height of 2 feet to find the maximum height above ground:
Maximum Height = h + 2 feet
By plugging in the values, we can find the maximum height to be:
Maximum Height = (0 - 16900) / (-64.4) + 2 ≈ 264.91 feet (rounded to the nearest hundredth).
Therefore, the maximum height attained by the tennis ball is approximately 264.91 feet.
Determine the values of the constants b and c so that the function given below is differentiable. f(x)={2xbx2+cxx≤1x>1
To make the function differentiable, we need to make it continuous at x = 1 by ensuring that both sides of the function have the same value. The values of the constants b and c are b = 1 - c, where c is any real number.
Explanation:The function given is:
f(x)={2xbx2+cxx ≤ 1 x > 1
To determine the values of the constants b and c such that the function is differentiable, we need to make sure that the function is continuous at x = 1 and both sides of the function have the same derivative at x = 1.
To do this, we need to find the limits of the function as x approaches 1 from both the left and the right sides.
From the given function, we can see that when x ≤ 1, the function is a polynomial and is differentiable for any value of b and c.
However, when x > 1, the function is not differentiable unless we choose the values of b and c such that the function becomes continuous at x = 1.
To make the function continuous, we need to make sure that both sides of the function have the same value at x = 1.
Substituting x = 1 into the given function, we have 2b(1)(1) + c(1) = b + c = 1 (since the function should be continuous at x = 1).
Therefore, the values of the constants b and c that make the function differentiable are b = 1 - c, where c is any real number.

Assume the least squares equation is ŷ = 10 + 20x. what does the value of 10 in the equation indicate? when x = 0, y = 10. x increases by 10 for each unit increase in y. y increases by 10 for each unit increase in x. it is the error of estimation.
The value of 10 in the equation ŷ = 10 + 20x represents the y-intercept, which is the value of y when x equals zero.
Explanation:The value of 10 in the equation ŷ = 10 + 20x represents the y-intercept. In the context of the least squares equation, the y-intercept is the value of y when x equals zero. So when x = 0, y = 10, indicating that the initial value of y is 10.
