Answer:
3 4/5
Step-by-step explanation:
7 3/10 - 3 9/10=
In this case 3/10 - 9/10 is cannot be so we have to borrow 1 whole from 7
so, 7 3/10 will become 7 3/10 + 1 or to add we have to change 1 as 10/10, any way 1 and 10/10 is equal but in this case we will use 10/10 to add 1 whole to 3/10 and minus 1 whole to 7
so, 3/10 + 10/10 = 13/10
and 7 - 1 = 6
so, 7 3/10 as 6 13/10
any way 7 3/10 and 6 13/10 is equal but, in this case we have to use 6 13/10 to minus, because 7 3/10 is cannot be
so, 6 13/10 - 3 9/10 =
=3 4/10 or 3 2/5

Step-by-step explanation:
Following are weights, in pounds, of two-month-old baby girls. It is reasonable to assume that the population is approximately normal.
12.32 11.87 12.34 11.48 12.66
8.51 14.13 12.95 9.34 8.63
Required:
a. Construct a interval for the mean weight of two-month-old baby girls.
b. According to the National Health Statistics Reports, the mean weight of two—month-old baby boys is 13.9 pounds. Based on the confidence interval, is it reasonable to believe that the mean weight of two-month—old baby girls may be the same as that of two-month-old baby boys? Explain.
Answer:
10.224 < μ < 12.622 ;
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.
Step-by-step explanation:
The confidence interval is given as :
Mean ± Margin of Error
margin of error = Zcritical * standard deviation /sqrt(n)
n = sample size
From the data:
12.32, 11.87, 12.34, 11.48, 12.66, 8.51, 14.13, 12.95, 9.34, 8.63
From the data:
Using calculator :
Mean, = 11.423
Standard deviation, s = 1.934
Zcritical at 95% confidence interval = 1.96
Sample size, n = 10
Margin of Error = 1.96* 1.934/sqrt(10) = 1.199
Lower boundary = 11.423 - 1.199 = 10.224
Upper boundary = 11.423 + 1.199 = 12.622
10.224 < μ < 12.622
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.

what the total area of a rectangular prism with a hight of 17feet a width of 12 feet and a thickness of 10 feet ?
Answer:
[tex]A=988\ \text{feet}^2[/tex]
Step-by-step explanation:
Given that,
The height, width and the thickness of a rectangular prism are 17 feet, 12 feet and 10 feet.
We need to find the area of a rectangular prism. The formula for the ara of rectangular prism is given by :
[tex]A=2(lb+bh+hl)[/tex]
Substitute all the values,
[tex]A=2(17\times 12+12\times 10+10\times 17)\\\\A=2\times 494\\\\A=988\ \text{feet}^2[/tex]
So, the area of the rectangular prism is equal to [tex]988\ \text{feet}^2[/tex].

The circumference of a circular island is 34.54 miles. What is the area of the
island?
Answer:
A = 94.99
Step-by-step explanation:
C = 2(3.14)r
34.54 = 2(3.14)r
34.54 = 6.28r
r = 34.54/6.28
r = 5.5
A = (3.14)r²
A = (3.14)5.5²
A = (3.14)30.25
A = 94.985
Answer:
95miles²
Step-by-step explanation:
The circumference of a circular island = 34.54 miles.
2πr=34.54miles
πr=17.27mile
r=17.27/πmile
the area of the island=πr²=π×{17.27/π}²=95miles² approx

Step-by-step explanation:
Given that,
Radius of cone, r = 7 inches
Slant height of the cone, l = 11 inches
We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :
[tex]h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}[/tex]

A water balloon was launched into the top of the hill 38 feet above the ground
Answer: -71.104 ft/sec
Step-by-step explanation:So you need to know how fast the balloon is moving when it hits this person's head. velocity is based on time. So you need the time that it hits this person's head. You can get time from the position equation. Because the balloon hits this person's head 6 feet from the ground, you know that the final position is at 6 so you plug that into the position equation and solve for t. You look and see what the appropriate t value is and plug it into the velocity equation and see what the answer is.
6=-16t^2+40t+60
0=-16t^2+40t+54
plug in those values into the quadratic formula or your calculator and you get:
t = -.972
or
t = 3.472
since you can't have negative time, the other answer must be it.
So you then plug it in and solve.
v(3.472) = -32(3.472) + 40
which is approximately -71.104 ft/sec
or if they just want speed, 71.104 ft/sec. (remember, speed is velocity without direction)

A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through the points (0, 2) and (8, -4). The equation of line t is y = −3/4 x + 2.

Graph the line with slope

and y-intercept -9.
The graph is shown in the attached image.
The graph of the line is a straight line with points on are: (0, -9), (3, -5) and (6, -1).
Given that a line has a slope of 4/3 and the y-intercept is -9, we need to graph the line,
To graph the line with a slope of 4/3 and a y-intercept of -9, we can use the slope-intercept form of a linear equation, which is y = mx + b.
Here, the slope (m) is 4/3, and the y-intercept (b) is -9.
Start by plotting the y-intercept, which is the point (0, -9).
Next, use the slope to determine the direction of the line. The slope 4/3 means that for every 4 units you move up, you need to move 3 units to the right.
So, from the y-intercept (0, -9), move up 4 units and then move to the right 3 units to find the next point on the line. This point would be (3, -5).
Repeat this process to find more points on the line. Move up 4 units and to the right 3 units from the previous point (3, -5) to get (6, -1).
You can continue this process to find more points if desired.
Once you have a few points, connect them with a straight line to graph the line.
The graph of the line with a slope of 4/3 and a y-intercept of -9 is attached in the solution.
