Total no. of births = 2000
Births of girls = 64
Birth% of girls
[tex] = \frac{64}{2000} \times 100[/tex]
[tex] = \frac{64}{20} [/tex]
[tex] = \frac{6.4}{2} [/tex]
[tex] = 3.2\%[/tex]
Hence, the number of girls are significantly low.

The Miller's are comparing babysitting services for their two children.
The Babysitter's Block charges a rate of $15 an hour per child plus an initial fee of $25 per household.
Super Sitters charges a flat rate of $20 an hour per child.
For ________hours of service, both babysitting services would cost the same.
Answer:
After 5 hours of service, both babysitting services would cost the same.
Step-by-step explanation:
Babysitter's Block: y = 15x + 25
Super Sitters: y = 20x
15x + 25 = 20x
Subtract 15x from both sides;
25 = 5x
Divide both sides by 5;
x = 5
For 5 hours of service, both babysitting services would cost the same.

Graphs which present the values on the horizontal axis and the number of times this occurs on the vertical axis are known as what?
Answer:
The horizontal axis represents TIME
Step-by-step explanation:
In a time-series plot, the horizontal axis represents time, and the vertical axis represents the value of the variable we are measuring. -The values of the variable are plotted at each of the times, then the points are connected with straight lines.
A rectangle has a perimeter of 32 in. Find the length and width of the rectangle under which the area is the largest.
a. Let the width to be x and the length to be y , then the quantity to be maximized is (expressed as a function of both x and y) A=_____
b. The condition that x and y must satisfy is y=______
Answer:
Length of the rectangle is 8 in and the breadth is 8 in.
a. [tex]A=xy[/tex]
b. [tex]y=16-x[/tex]
Step-by-step explanation:
Length = x
Breadth = y
Area is given by [tex]A=xy[/tex]
Perimeter of rectangle is given by
[tex]2(x+y)=32\\\Rightarrow x+y=16\\\Rightarrow y=16-x[/tex]
The condition that x and must satisfy is [tex]y=16-x[/tex]
So, area is
[tex]A(x)=x(16-x)\\\Rightarrow A(x)=16x-x^2[/tex]
Differentiating with respect to x we get
[tex]A'(x)=16-2x[/tex]
Equating with zero
[tex]0=16-2x\\\Rightarrow x=\dfrac{16}{2}\\\Rightarrow x=8[/tex]
Double derivative of A(x)
[tex]A''(x)=-2[/tex]
So [tex]A''(x)<0[/tex] which means [tex]A(x)[/tex] is maximum at [tex]x = 8[/tex]
[tex]y=16-x=16-8\\\Rightarrow y=8[/tex]
So length of the rectangle is 8 in and the breadth is 8 in.

Answer:
Below in bold.
Step-by-step explanation:
5. 1/8 and 0.125 = 12.5%
6. 6/100 = 3/50.
and 6/100 = 0.06.
7. 7/9 = 0.777....
and 77.78%.
8. 44/100 = 11/25.
and 0.44*100 = 44%
9. 625/1000 = 625/125 / 1000 / 125 = 5/8.
and 0.625.
10. 13/25 = 13*4/25/4 = 52/100 = 0.52
and 0.52 * 100 = 52%.

If Mr Mantle invests $15,000 in an account with 8% interest compounded
weekly how much would he have after 9 years?
a) $19,019,635.24
b) $16,119.74
c) $30,799.45
d) $30,798.77
Answer: c) $30,799.45
Step-by-step explanation:
Assuming there are 52 weeks in a year, the rate and time would be converted to;
Rate = 8%/52 = 8/52%
No. of periods = 9 years * 52 weeks = 468
The amount Mr Mantle would have is;
= 15,000 * ( 1 + 8/52%) ⁴⁶⁸
= $30,799.45276
= $30,799.45

Find 2 consecutive positive odd integers such that 4 times the larger is 29 more
than three times the smaller?
Answer:
21 and 23Step-by-step explanation:
Two integers are:
x and x + 2The equation and solution:
4(x + 2) = 3x + 294x + 8 = 3x + 294x - 3x = 29 - 8x = 21And
x + 2 = 23Which has the greater value? The sum of 89 and 45 or the difference between 89 and 45
Answer:
The sum of 89 and 45
Step-by-step explanation:
Because the sum of 89 and 45 is 134 and the difference of 89 and 45 is 44. And 134 > 44

Answer:
27 in
Step-by-step explanation:
The relationship between angle A, adjacent side AC, and hypotenuse AB is ...
Cos = Adjacent/Hypotenuse
cos(A) = AC/AB
Multiplying by AB, we get ...
AC = AB·cos(A)
AC = (30 in)cos(25°)
AC ≈ 27 in

Decide which of the two given prices is the better deal and explain why. You can buy shampoo in a 6-ounce bottle for $2.29 or in a 15-ounce bottle for $.10.19
Answer:
The 6 oz bottle
Step-by-step explanation:
When you simplify it to see how much per ounce each costs, the 6-oz has the better price.
2.29/6 = 0.381666....
10.19/15 = 0.6793....
the second bottle cost more per ounce, so the 6 oz bottle has the better deal

Answer:
maximum: 25 121/150 mpg at 47 1/3 mphminimum: 21.3 mpg at 30 mphStep-by-step explanation:
A graph can be helpful. It can show the locations of the maximum and minimum.
__
The maximum is found at the vertex of the parabola, located where ...
x = -b/(2a)
x = -1.42/(2(-0.015)) = 47 1/3
The value M(47 1/3) is ...
M(47 1/3) = (-0.015(47 1/3) +1.42)(47 1/3) -7.8 = 0.71(47 1/3) -7.8 = 25 121/150
The maximum gas mileage is 25 121/150 ≈ 25.8067 mpg at 47 1/3 mph.
__
The minimum will be at one end or the other of the interval. Here, the maximum is farther from the lower end of the domain, so we expect to find the minimum there:
M(30) = (-0.015(30) +1.42)(30) -7.8 = 0.97(30) -7.8 = 21.3
The absolute minimum gas mileage is 21.3 mpg at 30 mph.
