Step-by-step explanation:
The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models the data in the table. A 2-column table with 5 rows. The first column is labeled time (seconds) with entries 0, 0. 5, 1, 2001. 5, 2. The second column is labeled height (feet) with entries 100, 96, 84, 65, 37. For which value of x would this model make the least sense to use? –2. 75 0. 25 1. 75 2. 25.
The given model would make the least sense to use for x=-2.75.
the given function is:
[tex]h(x)= -16x^2 +100[/tex]
a quadratic relationship,
where
h is the height in feet
x is the time in seconds
what is kinetic energy?Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) = [tex]-16*(-2.75)^2+100 = -21\\[/tex]
h(0.25) = [tex]-16*0.25^2 +100=99[/tex][tex]-0.25^2*16+100=99[/tex]
h(1.75) = [tex]-16*1.75^2+100=51[/tex]
h(25) = [tex]-16*2.25^2+100= 19[/tex]
therefore, x=-2.75 this model would make the least sense to use

A study on students drinking habits asks a random sample of 60 male uf students how many alcoholic beverages they have consumed in the past week. The sample reveals an average of 5. 84 alcoholic drinks, with a standard deviation of 4. 98. Construct a 95% confidence interval for the true average number of alcoholic drinks all uf male students have in a one week period.
Answer:
Using the t-distribution, the 99% confidence interval for the true average number of alcoholic drinks all UF female students (over 21) have in a one week period is (3.25, 4.85).
We have the standard deviation for the sample, thus, the t-distribution is used to solve this question.
First, we find the number of degrees of freedom, which is the sample size subtracted by 1, thus:
Then, using a calculator, with and 169 df, we have that the two-tailed critical value is .
The margin of error is:
In this problem, , then:
The confidence interval is:

What is an expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.
Given are the expressions, we need to put the parentheses to equate the values,
1) 9+12÷3+4÷2+1·2 = 2,
9+12 = 21, 3+4 = 7, 1+2 = 3
(9+12)÷(3+4)÷(2+1)·2 = 21 ÷ 7 ÷ 3 · 2 = 2
(9+12)÷(3+4)÷(2+1)·2 = 2
2) 9+12÷3+4÷2+1·2 = 8
(9+12) = 21, (2+1·2) = 6
(9+12÷3)+(4÷2+1·2) = 21 ÷ 3 + 1 = 8
(9+12÷3)+(4÷2+1·2) = 8
3) 9+12÷3+4÷2+1·2 = 11
9+12 = 21, 4÷2 = 2, 1·2 = 2
(9+12)÷3+(4÷2)+(1·2) = 21 ÷ 3 + 2 +2 = 7 + 2 + 2 = 11
(9+12)÷3+(4÷2)+(1·2) = 11
4) 9+12÷3+4÷2+1·2 = 12
(9+12)÷(3+4)÷(2+1·2) = 12
Hence, the answers are (9+12)÷(3+4)÷(2+1)·2 = 2, (9+12÷3)+(4÷2+1·2) = 8, (9+12)÷3+(4÷2)+(1·2) = 11 and (9+12)÷(3+4)÷(2+1·2) = 12.

Answer:
1044cm²
Step-by-step explanation:
first split the polygon into two shapes
46-21=25
so the length of a shape is 25
so 30x25=750
then 21*14=294
then 750+294=1044cm²
Answer:
1044 cm²
Step-by-step explanation:
Subdivide the polygon into two rectangles by drawing a vertical line from the interior vertex of the L-shape.
Area of a rectangle = width x length
⇒ area of largest rectangle (left) = (46 - 21) x 30 = 750 cm²
⇒ area of smallest rectangle (right) = 14 x 21 = 294 cm²
Total area of shape = 750 + 294 = 1044 cm²
55 less than a number n is equal to the product of 25 and -18. What is the number?
Answer:
-395

n - 55 = 25 * (-18)
n - 55 = -450
so
n = -450 + 55 = -395
Answer:
n - 55 = 25 x (-18)
n - 55 = -450
+55 +55
n = -395
