A recent survey showed that 23.3 million adults have cut the cord on cable TV services, a 30% increase fron the previous year. If this trend continues, how many millions if adults can be expected to cut the cord next year?
Answers
Answer:
30,290,000 people
Step-by-step explanation:
The question is asking if the trend continues from the PREVIOUS year, so we would find the 30% of 23,300,000
23,300,000/100 = 233,000 = 1%
233,000 x 30 = 6,990,000
23,300,000 = 6,990,000 = 30,290,000
Part of the graph of the function f(x) = (x – 1)(x + 7) is shown below.
Which statements about the function are true? Select three options.
The vertex of the function is at (–4,–15).
The vertex of the function is at (–3,–16).
The graph is increasing on the interval x > –3.
The graph is positive only on the intervals where x < –7 and where
x > 1.
The graph is negative on the interval x < –4.
Answers
Answer:
The vertex of the function is at (–3,–16)
The graph is increasing on the interval x > –3
The graph is positive only on the intervals where x < –7 and where
x > 1.
Step-by-step explanation:
The graph of \(f(x)=(x-1)(x+7)\) has clear zeroes at \(x=1\) and \(x=-7\), showing that \(f(x) > 0\) when \(x < -7\) and \(x > 1\). To determine where the vertex is, we can complete the square:
\(f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16\)
So, we can see the vertex is (-3,-16), meaning that where \(x > -3\), the function will be increasing on that interval

-1000 2/3 is not real fraction. True or false
Answers
True, While "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.
The statement "-1000 2/3 is not a real fraction" is true. A real fraction is a mathematical expression that represents a ratio of two real numbers. In a fraction, the numerator and denominator are both real numbers, and they can be positive, negative, or zero.
In the given statement, "-1000 2/3" is not a valid representation of a fraction. The presence of a space between "-1000" and "2/3" suggests that they are separate entities rather than being part of a single fraction.
To represent a mixed number (a whole number combined with a fraction), a space or a plus sign is typically used between the whole number and the fraction. For example, a valid representation of a mixed number would be "-1000 2/3" or "-1000 + 2/3". However, without the proper formatting, "-1000 2/3" is not considered a real fraction.
It's important to note that "-1000 2/3" can still be expressed as an improper fraction. To convert it into an improper fraction, we multiply the whole number (-1000) by the denominator of the fraction (3) and add the numerator (2). The result would be (-1000 * 3 + 2) / 3 = (-3000 + 2) / 3 = -2998/3.
In conclusion, while "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.

Answers
let the four integers are,
a -1 , a , a + 1 , a + 2
so the sum is = -2
(a-1) + a + (a+1) + (a+ 2) = -2
4a + 2 = -2
4a = -2 - 2
4a = -4
a = -1
The first (smallest) integer = a-1 = -1 -1 = -2
The second infeger = a = - 1
The third integer = a + 1 = -1 + 1 = 0

Twelve cards are numbered from 1 to 12 and placed in a box. One card is selected at random and not replaced. Another is randomly selected. What is the probability of selecting two even numbers?
Answers
In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:
In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).
The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22

Answers
The value of d for the given angles will be equal to d = 13. The correct option is B.
What is the complementary angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Complementary angles are formed when the sum of two angles equals 90 degrees. 30 degrees and 60 degrees, for example, are complementary angles.
Given that one angle measures 18° and another angle measures (6d − 6)°.
The value of d will be calculated as,
18 + 6d - 6 = 90
6d + 12 = 90
6d = 90 - 18
6d = 78

The slope of the line that passes through the points (7,-4) and (11,-4) is 0.
The slope of a line is found by using the formula:
slope = (change in y)/(change in x)
To find the change in y, subtract the y-coordinate of one point from the y-coordinate of the other point:
-4 - (-4) = 0
To find the change in x, subtract the x-coordinate of one point from the x-coordinate of the other point:

which statements about doubling in investment are true check all that apply an investment of $5000 will double in six years at an annual compound interest rate of 12% An investment of $1000 will double at an annual compound interest rate of 18% in six years an investment of $350 will double in nine years At a compound interest rate of 8% an investment of $2000 will double at a simple interest rate of 5% in 20 years and investment of $700 will double in 12 years at a simple interest rate of 6%
Answers
The following statement are true:
An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.An investment of $350 will double in 9 years at a compound interest rate of 8%. An investment of $2000 will double at a simple interest rate of 5% in 20 years.What is rule 72?It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
Using the formula
time for doubling money= 72/R
First, An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.So, 72/12 = 6 years
Thus, It will take 6 years to double the investment. This statement is true.
Second, An investment of $1000 will double at an annual compound interest rate of 18% in 6 years.So, 72/18 = 4 years
Thus, It will take 4 years to double the investment. This statement is not true.
Third, An investment of $350 will double in 9 years at a compound interest rate of 8%.so, 72/8= 9 years.
Thus, It will take 9 years to double the investment. This statement is true.
Fourth, An investment of $2000 will double at a simple interest rate of 5% in 20 years.So, interest = PRT/100
I = (2000 × 0.05 × 20)
I = $2000
Thus, This statement is true.
Fifth, An investment of $700 will double in 12 years at a simple interest rate of 6%Interest = ( 700 × 0.06 × 12 ) = $504
Amount after 12 years
=700 + 504
= $1204.
Thus, This statement is not true.
