Answer:
[tex]Students = 192[/tex]
[tex]\%Boys = 72\%[/tex]
Step-by-step explanation:
Given
See attachment for proper table
Solving (a): Students who spend more time playing games on tablets
To do this, we simply consider the playing games column.
The student are:
[tex]Students = 192[/tex]
Solving (b): The percentage of boys.
From the same columns, the numbe of boys are:
[tex]Boys = 138[/tex]
So, the percentage is:
[tex]\%Boys = \frac{Boys}{Students}* 100\%[/tex]
[tex]\%Boys = \frac{138}{192}* 100\%[/tex]
[tex]\%Boys = 0.71875* 100\%[/tex]
[tex]\%Boys = 71.875\%[/tex]
Approximate
[tex]\%Boys = 72\%[/tex]

Step-by-step explanation:
this should be right
Answer:
[tex](x + 2)^{2} + y^{2} = 45[/tex]
Step-by-step explanation:
The radius (r) of the circle is the distance between (-2, 0) and (-5, -6)
r = [tex]\sqrt{(-2 + 5)^{2} + (0 + 6)^{2} } = \sqrt{3^{2} + 6^{2} } = \sqrt{9 + 36} = \sqrt{45}[/tex]
[tex]r^{2}[/tex] = 45
[tex](x + 2)^{2} + y^{2} = 45[/tex] is the equation of the circle

Mark for review (Will be highlighted on the review page)
Alaviation
Answer:
D.(3, 3)
Step-by-step explanation:
The equation of a straight line is given as:
y = mx + c;
where x, y are variables, m is the slope of the line, c is the y intercept.
From the graph, we can see that line 1 passes through (6,0) and (0,6).
The equation of line 1 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{6-0}{0-6} (x-6)\\\\y=-x + 6\ \ \ (1)[/tex]
Line 2 passes through (6, 5) and (0, 1)
The equation of line 2 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-5=\frac{1-5}{0-6} (x-6)\\\\y=\frac{2}{3}x + 1\ \ \ (2)[/tex]
To get the coordinates of the intersection of the two lines, we solve equation 1 and 2 simultaneously using a calculator. This gives:
x = 3, y = 3
Therefore the two lines meet at (3, 3)
The value of point B is greater than the value of point A in this number line.Why is this true?
Answer:
Point B is to the right of point A
Step-by-step explanation:
On a number line, the mid value is usually 0 with positive and negative numbers positioned to the either sides of the midpoint 0, the negative numbers are arranged to the left and the positive numbers are written to the right. With this in mind and the knowledge that positive numbers are always greater than negative numbera. Then we can conclude that point B is greater than point A because point B is positive and point A is negative because point B is to the right of Point A.
Find the volume of a cylinder prism with radius of 3 and height of 11
Answer:
310.86
Step-by-step explanation:
so V=Bh
and B=pi *r^2
so that means 3.14*9 (since 3^2 is 9)
3.14*9=28.26
then 28.26*11= 310.86

The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.70 meters and the sample standard deviation was 1.13 meters.
Required:
Construct a 95% confidence interval (in meters) for μ, the population mean following distance while talking on a mobile phone for the population of taxi drivers.
Answer:
(3.387 ; 4.013)
Step-by-step explanation:
Confidence interval :
Xbar ± standard Error
Standard Error = Zcritical * s/√n
n = 50 ; s = 1.13 ; xbar = 3.70
Zcritical at 95% = 1.96
Standard Error = 1.96 * 1.13/√50
Standard Error = 0.3132200
Lower boundary : (3.70 - 0.313) = 3.387
Upper boundary : (3.70 + 0.313) = 4.013
(3.387 ; 4.013)

Answer:
(a) $1430
(b) $1340
(c) Debit card
Step-by-step explanation:
(a) The debit card is funded by Jenny's checking account, so it cannot be used to spend more than her checking account balance. The most Jenny can spend using her debit card is $1430.
__
(b) Amounts purchased using her credit card add to the credit balance. The most Jenny can purchase is the difference between her current balance and her credit limit.
Limit - balance = $2350 -1010 = $1340
The most Jenny can spend using her credit card is $1340.
__
(c) For a purchase of $1400, the amount available on Jenny's credit card is insufficient. She can make the purchase using her debit card.
