Answer:
The answer is D. Because the confidence interval is positive, the researcher can conclude there is a greater proportion of men than women who watch television regularly.
Step-by-step explanation:
We can agree that the lower and upper bound of the confidence interval is positive, meaning that because the confidence interval represents the range about the difference in proportions, it being positive must mean that one of the proportions is bigger than the other. Quickly calculating the proportions shows us that men (56 / 70) watch television more frequently than women (47 / 85).
Because the confidence interval is positive, the researcher can conclude that men watch television more frequently than women. Option D is correct.
What is Statistic?The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
It is supposed to be agreed that the bottom and upper bounds of the confidence interval are positive, which means that because the confidence interval represents the range of the proportional difference, it must be positive if one of the proportions is larger than the other. Men (56 / 70) watch television more frequently than women (47 / 85), according to a quick calculation.
Thus, Because the confidence interval is positive, the researcher can conclude that men watch television more frequently than women. Option D is correct.

In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work
Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°
the volume of sphere is increaseing
at the Constant rate of 10cm²lsee-
Calculate the rate of increase of
the surface area
at the Instant
When the radus is 5cm. What
is the radius of the sphere when
the surface are is increasing at 2cm
Volume of a sphere:
V = 4/3 π r ³
Differentiate V with respect to time t :
dV/dt = 4π r ² dr/dt
Surface area of a sphere:
A = 4π r ²
Differentiate A with respect to t :
dA/dt = 8π r dr/dt
You're given that the volume is increasing at a constant rate, dV/dt = 10 cm³/s, so
10 cm³/s = 4π r ² dr/dt
Solve for dr/dt (the rate of change of the sphere's radius):
dr/dt = 5/(2π r ²) cm³/s
Substitute this into the equation for dA/dt :
dA/dt = 8π r (5/(2π r ²) cm³/s)
dA/dt = 20/r cm³/s
At the moment the radius is r = 5 cm, the surface area is increasing at a rate of
dA/dt = 20/(5 cm) cm³/s = 4 cm²/s
When the surface area is increasing at a rate of dA/dt = 2 cm²/s, the radius r is such that
2 cm²/s = 20/r cm³/s
which happens when the radius is
r = 20/2 (cm³/s) / (cm²/s) = 10 cm

The y-intercept has coordinates of (0, 1)Put the following equation of a line into slope-intercept form, simplifying all fractions.
3x+2y=14
Answer:
y = -3/2x + 7
Step-by-step explanation:
First, let's identify what slope-intercept form is: y = mx + b
We have:
3x + 2y = 14
Right away, we can see that we need to 1) move x to the right side of the equation and 2) simplify y.
1) To move x to the right side of the equation, subtract 3x from both sides.
2y = -3x + 14
2) To simplify y, divide both sides by 2. When dividing the right side by 2, you need to evaluate each component (3x and 14, not just one)
y = -3/2x + 7
This is your equation in slope-intercept form.

Answer:
-12.25
Step-by-step explanation:
Given the expression
1/4-20 x 5/8
To simplify, we will use PEMDAS rule
Solving the multiplication part
1/4-20 x 5/8
= 1/4 - (20*5/8)
= 1/4 - 100/8
Find the LCM
= 2-100/8
= -98/8
= -12.25
Hence it has a length of -12.25
PLEASE HELP ME THIS IS IMPORTANT!! Ronnie, Bobby, and mike are singers from the group New Edition. They
are raising money for studio time. Ronnie raised $30 more than Mike, and
Bobby raised $12 less than Ronnie. They collected $432 in total. How
much did Ronnie collect? And how much did mike collect? Also how much did mike collect?
Answer:
786768
Step-by-step explanation:
Answer:
Amount raised by Ronnie = $158
Amount raised by Bobby = $146
Amount raised by Mike = $128
Step-by-step explanation:
Amount raised by Ronnie = r
Amount raised by Bobby = b
Amount raised by Mike = m
r=m+30
b=r-12
r+b+m=432
Put b in terms of m:
b=r-12
b=(m+30)-12
b=m+18
r+b+m=432
(m+30)+(m+18)+m=432
3m+48=432
3m=384
m=128
b=m+18
b=128+18
b=146
r=m+30
r=128+30
r=158

have a wonderful day!!!
Answer:
=127.23
Step-by-step explanation:
we can start of by finding the area of a CIRCLE
18/2=9
9=radius
area of circle= pi*r squared
9 squared=81*pi=254.4690
Now we can half the area of the circle to find out the area of the semi circle as a semi circle is just half a circle therefore half the area of a circle
254.469/2=127.2345
127.2345=127.23
=127.23

Can the sides of a triangle have lengths 6, 17, and 19?
Answer: pretty sure
Step-by-step explanation:
Suppose that P(n) is a propositional function. Determine for which improper subset of the domain of n the statement P(n) must be true if a) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 2) is true. b) P(0) and P(1) are true; for all nonnegative integers n, if P(n) and P(n 1) are true, then P(n 2) is true
Answer:
a) P(n) is true for all 'n' in the set ; { 0,2,4,6,8 ….. }
b) P(n) is true for all 'n' in the set ; { 0,1,2,3,4,5 ............ }
Step-by-step explanation:
a) As P(0) is true
we will assume that
P(2) is trueP(4) is true P(6) is truethis simply means that ; P(n) is true for all 'n' in the set
{ 0,2,4,6,8 ….. }
b) since P(0) and P(1) are true
we will assume that
P( 0+2 ) = P(2) is truealso P(1) and P(2) are true
we will assume that
P(1+2) = P(3) is trueAlso from the previous answers it can be seen that P(2) + P(3) is true
we will assume
P(2+2) = P(4) is trueThis simply means that P(n) is true for all 'n' in the set
{ 0,1,2,3,4,5 ............ }

Calls to a customer service center last on average 1.4 minutes with a standard deviation of 1.7 minutes. An operator in the call center is required to answer 52 calls each day. Assume the call times are independent. What is the expected total amount of time in minutes the operator will spend on the calls each day
Answer:
the expected total amount of time in minutes is 88.4
Step-by-step explanation:
The computation of the expected total amount of time in minutes is given below:
= Standard deviation × needed to answer calls each day
= 1.7 × 52
= 88.4
hence, the expected total amount of time in minutes is 88.4
