Solve the inequality: 4x-2<10
Answer:
w < 3
Step-by-step explanation:
One can solve an algebraic inequality just like how one solves an algebraic equation, by using inverse operations. The only major difference is that when one multiplies or divides by a negative number, one must remember to flip the inequality sign, this rule does not come into play in the given inequality.
4x - 2 < 10
+2 +2
4x < 12
/4 /4

Nielsen Rating: The television show nbc Sunday night football broadcast a game between the colts and patriots and received a share of 22, meaning that among the tv sets in use, 22% are turned to that game (based on data from Nielsen Media Research). An advertiser wants to obtain a second opinion by conducting its own surveys and a pilot survey begins with 20 households having tv sets in use at the time of that same nbc Sunday night football broadcast.
a. Find the probability that none of the households are turned to nbc Sunday night football (3 digits)
b. Find the probability that at least one of the households is turned to nbc Sunday night football.(3 digits)
c. Find the probability that at most one of the households is turned to nbc Sunday night football (3 digits)
d. If at most one household is turned to nbc Sunday night football, does it appear that the 22% share value is wrong? Why or why not?
Answer:
a. 0.007 = 0.7% probability that none of the households are turned to nbc Sunday night football
b. 0.993 = 99.3% probability that at least one of the households is turned to nbc Sunday night football.
c. 0.046 = 4.6% probability that at most one of the households is turned to nbc Sunday night football
d. 1 is less than 2.5 standard deviations below the mean, so having at most one people watching shouldn't be considered an unusual outcome, which means that the 22% share values does not appear wrong.
Step-by-step explanation:
For each household, there are only two possible outcomes. Either it is tuned to Sunday Night Football, or it is not. The probability of a household being tuned to Sunday Night Football is independent of any other household. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
22% are turned to that game
This means that [tex]p = 0.22[/tex]
Sample of 20 households:
This means that [tex]n = 20[/tex]
a. Find the probability that none of the households are turned to nbc Sunday night football:
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.22)^{0}.(0.78)^{20} = 0.007[/tex]
0.007 = 0.7% probability that none of the households are turned to nbc Sunday night football.
b. Find the probability that at least one of the households is turned to nbc Sunday night football.
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
Since P(X = 0) = 0.007
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.007 = 0.993[/tex]
0.993 = 99.3% probability that at least one of the households is turned to nbc Sunday night football.
c. Find the probability that at most one of the households is turned to nbc Sunday night football (3 digits)
This is
[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.22)^{0}.(0.78)^{20} = 0.007[/tex]
[tex]P(X = 1) = C_{20,1}.(0.22)^{1}.(0.78)^{19} = 0.039[/tex]
[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.007 + 0.039 = 0.046[/tex]
0.046 = 4.6% probability that at most one of the households is turned to nbc Sunday night football.
d. If at most one household is turned to nbc Sunday night football, does it appear that the 22% share value is wrong? Why or why not?
A measure is considered unusually low if it is more than two and a half standard deviations below the mean.
The mean is:
[tex]E(X) = np = 20*0.22 = 4.4[/tex]
The standard deviation is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{20*0.22*0.78} = 1.8526[/tex]
4.4 - 2.5*1.8526 = -0.2.
1 is less than 2.5 standard deviations below the mean, so having at most one people watching shouldn't be considered an unusual outcome, which means that the 22% share values does not appear wrong.

Which product is less than 5/8 help l will give you brainlest
Answer:
4/3 x 5/8 is correct
Step-by-step explanation:
Answer: C 7/10 * 5/8
Step-by-step explanation:
4/3 * 5/8 = 20 / 24 = 5 / 6
3/2 * 5/8 = 15 / 16
7/10 * 5/8 = 35/80 = 7 / 16
9/7 * 5/8 = 45 / 56
5/8 = 10/16
7/16 < 10/16
7/16 < 5/8

Terry's brother can paint a room in 3 hours less than Terry can paint it. Working together they can complete the job in 2 hours. How much time would require Terry to paint the room working alone? Enter just the number no words.
Answer:
6
Step-by-step explanation:
the equation would be 2/(x-3) + 2/x = 1 derived from the work formula of T/A + T/B = 1; T representing total time working together, A/B respectively representing the two different rates of working. In the end Terry would spend 6 hours working alone.
Write an equation for a line perpendicular to y = 2 x + 4 and passing through the point ( − 2 , 3 ) . Express your answer in slope-intercept form.
Answer:
y = -1/2x + 2
Step-by-step explanation:
A perpendicular line will have a opposite reciprocal slope.
Since the line's slope is 2, the perpendicular line will have a slope of -1/2
Plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
3 = -1/2(-2) + b
3 = 1 + b
2 = b
Plug in the slope and b into y = mx + b
y = -1/2x + 2
So, the equation is y = -1/2x + 2

The more times you run a probability-based trial, the more likely you are to get close to the theoretical frequency.

Since 1 and 2 represent goals, just find the options that have three/four 2's and 1's. These are 5212, 2152, 2512, and 2112. Since there are 4 options out of 20, we can say our probability is 4/20
C
Since 1 and 2 represent goals, we have to find the options where there are no 1's or 2's. These are 6643, 3554, 4533, 6634, 4536, and 5546. Since there are 6 options out of 20, we can say our probability is 6/20
Find sin theta if cos theta is 4/5
Answer:
Step-by-step explanation:
hello :
cos²θ +sin²θ = 1 and cosθ =4/5
(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25
sin²θ = 9/25 = (3/5)²
sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

Answer: 19.101 miles north
Step-by-step explanation:
Now were given an right angled trinagle with the with the 2nd angle being 23 degrees and given a triangle leg length of 45 miles which is adjcent to the angle and were trying to find how find out how far north it went meaning were trying to find how far up it went thus trying to find the side opposite of the angle.
So now we know our facts we need a trig function which uses both the adjacent and opposites sides, that would be tangent.
