A spinner has 8 equal spaces. If you spin it, what is the probability that you 2 points
spin a number greater than 5?
Answer:
78
Step-by-step explanation:
probability of getting a 5 which is 78.
Another way to look at this is that if we know the probability of the result being 5, then the probability of it not being 5 is just one minus that probability. We know that 5 is just one out of the 8 possibilities, so
P5=18
So the probability of not 5 is
Pnot5=1−P5=1−18=78

The end of a minute hand on a clock is 5.5 inches from the center. How far will the minute hand travel over three days
Answer:
Step-by-step explanation:
Given :
Radius, r = Length of hour hand = 5.5 inches
A complete cycle is traveled in 24 hours ;
C = 2πr
C = 2 * π * 5.5 = 34.557519 inches
In 3 days : It will travel 3 full cycles
3 * C = 3 * 34.557519 inches
= 103.672557 inches
A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5

A new pain reliever is advertised as being 97%
effective. To 3 decimal places, what is the
probability that the pain reliever will be effective
in 12 independent trials?
A. 0.116
B. 0.694
C. 0.970
D. 0.847
Answer:
B. 0.694
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the pain reliever is advertised as being 97% effective, for it to be effective in 12 independent trials
= (97%) ^ 12
= 0.693842361
The is approximately 0.694 to 3 decimal places

Step-by-step explanation:
Circle upper left
The central angles all add up to 360 degrees
BC + CD + 148 = 360
But CD = BC
2BC + 148 = 360 Subtract 148 from both sides
2BC = 360 - 148 Combine
2BC = 212 Divide by 2
BC = 106

3 of the 5 arcs are marked as being equal.
Let each of them be called = x
3x + 41 + 82 = 360 Combine
3x + 123 = 360 Subtract 123 from Both sides.
3x = 360 - 123
3x = 237
x = 237 / 3
x = 79
BC = 79

Unless DE and FC are diameters, this can't be solved. I will assume they are.
FB + 48 + 22 = 180.
FB + 70 = 180
FB = 110
===========
FC = FB + BD + DC
180 = 110 + 22 + DC
180 = 132 + DC
DC = 180 - 132
DC = 48
===========
BC = BD + DC
BC = 22 + 48
BC = 70

Factor the trinomial 3x2 + 13x − 10 by grouping.
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
The factors of the trinomial 3x² + 13x - 10 is (3x-2)(x+5).
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
we have,
Trinomial= 3x² + 13x - 10
Now, factories using splitting the middle term we get
3x² + 13x - 10
= 3x² + 15x - 2x - 10
= 3x( x +5) - 2(x+ 5)
= (3x - 2) (x+ 5)
So, the factors are (3x- 2(x+5)

Answer:
$465
Step-by-step explanation:
The problem statement tells you h represents the number of hours, and the number of hours is 7.
It also tells you f represents the number of fixtures, and the number of fixtures is 9.
And, the problem statement tells you the charge is 15h+40f, which is 15 times the number of hours plus 40 times the number of fixtures. Then the charges are ...
15·7 +40·9 = 105 +360 = 465
Ben Frank charges $465 for the work.
Answer:
if it wants an equation, 105h+360f but if its all together then its 465$

Una persona hace un trabajo en 6 horas, una segunda hace el trabajo en 8 horas y una tercera hace el trabajo en 10 horas. Si las tres personas trabajan al mismo tiempo ¿Cuánto tiempo durarán haciendo el trabajo?
a) 1 16/47 horas.
b) 2 26/47 horas.
c) 3 1/47 horas.
d) 4 36/47 horas.
Answer:
b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]
Step-by-step explanation:
Tiempo necesario para completar el trabajo en primera persona = 6 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{6}[/tex]
Tiempo necesario para completar el trabajo por segunda persona = 8 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]
Tiempo necesario para completar el trabajo por tercera persona = 10 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{10}[/tex]
El tiempo necesario para completar el trabajo juntos viene dado por
[tex]\dfrac{1}{\dfrac{1}{6}+\dfrac{1}{8}+\dfrac{1}{10}}=\dfrac{1}{\dfrac{47}{120}}\\ =\dfrac{120}{47}=2\dfrac{26}{47}\ \text{horas}[/tex]
El tiempo necesario para completar el trabajo juntos es [tex]2\dfrac{26}{47}\ \text{horas}[/tex].
find the missing side of the triangle
Answer:
x= 8 km
Step-by-step explanation:
measurement used:
When getting measurement the missing side occupies 1 more than a half of 15km
Answer:
x = 8km
Step-by-step explanation:
Use Pythagorean Theorem:
c2 = a2 + b2
In the diagram given, the hypotenuse (c) is 17 so substitute these values into the equation
17^2 = x^2 + 15^2
Take 15 to the power 2, to the other side.
17^2 - 15^2 = x^2
Solve to get
64 = x2
Square root both sides so
x = 8
