Answer: (92, 128)
Step-by-step explanation:
According to the Empirical rule,
If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.
Given: Mean = 110
Standard deviation = 9
The interval of systolic blood pressures represent the middle 95% of males:
(110-2(9), 110+2(9))
= (110-18, 110+18)
= (92, 128)
Hence, the interval of systolic blood pressures that represent the middle 95 % of males = (92, 128)
Answer:
its 92, 128

Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800
A radial saw has a blade with a 6-in radius.
Suppose that blade spins at 1000 rpm.
Find the angular speed of the blade in
rad/min.
Answer:
The angular speed of the blade is of 166.67 rad/min
Step-by-step explanation:
The velocity, is given by the following equation:
[tex]v = rw[/tex]
In which r is the radius and w is the angular speed.
We use this relation to solve this question;
We have that:
[tex]v = 1000, r = 6[/tex]. We want to find w. So
[tex]v = rw[/tex]
[tex]1000 = 6w[/tex]
[tex]w = \frac{1000}{6}[/tex]
[tex]w = 166.67[/tex]
The angular speed of the blade is of 166.67 rad/min

All edges of a cube are expanding at a rate of 6 centimeters per second. (a) How fast is the volume changing when each edge is 5 centimeter(s)
Answer:
(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]
Step-by-step explanation:
Let x be the side of cube
[tex]\frac{dx}{dt}=6 cm/s[/tex]
We have to find the rate at which volume of cube changing when edge is 5 cm.
We know that
Volume of cube, V=[tex]x^3[/tex]
Differentiate w.r.t t
[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]
Substitute the values
[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]
[tex]\frac{dV}{dt}=450 cm^3/s[/tex]
Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

Write the series 1-0.5-2+ ... for 12 terms using summation notation
The summation notation for the given series is [tex]\sum_{n=1}^{12}(2.5-1.5n)[/tex]
The given series is,
[tex]1,-0.5,-2,........[/tex]
Since, [tex]-0.5-1=-2+0.5=-1.5[/tex]
Here we observe that, common difference between each term is - 1.5.
So, given series is an Arithmetic progression series.
First term, [tex]a=1[/tex], common difference, [tex]d=-1.5[/tex]
General term for AP series,
[tex]a_{n}=a+(n-1)d\\\\a_{n}=1+(n-1)*(-1.5)\\\\a_{n}=1-1.5n+1.5\\\\a_{n}=2.5-1.5n[/tex]
Hence, summation series up to 12 terms is,
[tex]\sum_{n=1}^{12}(2.5-1.5n)[/tex]
