x^3/x^1/6=x^a value of a in simplest form?
Answer: a = 17/6
Step-by-step explanation:
I will use two laws of indices to solve this question
1. x^a / x^b = x^(a-b)
2. x^a = x^b, => a = b
Using both laws
x³/x^1/6 = x^a
x^(3-1/6) = x^a
3 - 1/6 = a
a = 3 - 1/6
a = (18 - 1)/6 using LCM
a = 17/6

Helpppppppp. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil. Jason decides to test the land for oil. He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. What is the probability that the land has no oil and the test shows that it has oil? A. 0.09 B. 0.11 C. 0.36 D. 0.44
Answer:
Jason Inherit a land with a 45% chance of having oil.
Step-by-step explanation:
The probability of the land having oil is = P ( O) = 45 /100
The probability of the land having oil is= Q(O ) =55/100
The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.
The probability of the correct reading is= P(M)=80/100
The probability of the incorrect reading is=Q(M)=20/100
The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present × probability of the incorrect reading
Probability=P(O) x Q(M)
Probability=45/100 x 20/100
Probability=9/100
The probability of the test predicting no oil in land and the land has oil is 0.09 or 9%

Event A: lands on yellow.
Event B: lands on green.
Events A and B are a0 events.
Answer:
1/16
Events A+B are written (P) yellow : 1/4 * (P) green : 1/4
Ao event = (P) 1/4 * 1/4 = 1/16
Step-by-step explanation:
The probability of event A and event B is 1/16.
We have given that,
Event A: lands on yellow.
Event B: lands on green
Events A+B are written
yellow(P) = 1/4 * (P) green= 1/4
What is the meaning of probability?
Probability is defined as the likelihood of something occurring or the chance of something happening.
Ao event (P)=1/4 * 1/4
Event = 1/16
Therefore the probability of event A and event B is 1/16.

Can someone help me please
Answer:
B
Step-by-step explanation:
To find DC
c²=a²+b² (pythagorean theory)
c²=6²+8²
c²=36+64. c²=100. √100. c=10cm
thus D =10.
AD= 15-6=9
To find AC
c²=a²+b²
c²=15²+8²
c²=225+64. c²=289 √289. c=17
AC=17
perimeter is the distance around a figure thus ADC=9+10+17

Answer:
y = 3/2x - 1
Step-by-step explanation:
Slope intercept form = y = mx + b
m = slope of the line = -2/3
y = -2/3x + b
Plug in (-2, -2) and the perpendicular line is
y = 3/2x - 1

Solve for x given that CE = 36.
Show your work
Answer:
x=7
Step-by-step explanation:
CE = 36
CE = 9+(3x+6) = 9+6+3x = 15+3x
36= 15+3x
36-15 = 15-15+3x (removing 15 from left side also means removing 15 from right side)
21 = 3x
x= 21/3 = 7
Answer:
x=7
Step-by-step explanation:
First, I wrote down the equation.
3x+6=36-9
Then, I simplified it.
3x+6=27
Then, I moved the six from the right to the left.
3x=21
After that, I divided both sides by 3.
x=7

[tex]$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$[/tex]
Step-by-step explanation:
[tex]18x^2-24x+87=0[/tex]
Using Quadratic Formula
[tex]$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$[/tex]
[tex]$x=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:18\cdot \:87}}{2\cdot \:18}$[/tex]
Solving the discriminant:
[tex]\Delta = \left(-24\right)^2-4\cdot \:18\cdot \:87\\\Delta = 576-6264\\ \Delta=-5688[/tex]
[tex]$x= \frac{24 \pm \sqrt{-5688} }{36} $[/tex]
[tex]$x= \frac{24 \pm \sqrt{5688i} }{36} $[/tex]
Once [tex]\sqrt{5688} =\sqrt{2^3\cdot \:3^2\cdot \:79}=6\sqrt{158}[/tex]
[tex]$x=\frac{24\pm6\sqrt{158}i}{36}$[/tex]
Dividing the denominator and numerator by 6
[tex]$x=\frac{4\pm \sqrt{158}i}{6}$[/tex]
Now rewrite it:
[tex]$x=\frac{4}{6} \pm i\frac{\sqrt{158}}{6}$[/tex]
[tex]$x=\frac{2}{3} \pm i \frac{\sqrt{158}}{6}$[/tex]
or
[tex]$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$[/tex]
Hitting the baseball over the lights
Meanwhile, at the ballpark, Juan was practicing his hitting while talking to the girls
standing around watching. He started telling them how he hit the ball over the 50 foot
light tower yesterday. The girls were unsure that he really did that.
The formula for this hit is: H(x)=-16x^2+60x+4 where h is the height of the ball and x is the number of seconds the ball is in the air.
How long did the ball actually hang in the air?
Answer:
Approximately 3.8 seconds
Step-by-step explanation:
H(x)=-16x^2+60x+4
We want to find when the ball hits the ground, or where the zeros are

3/11 x 44/1 = 132/11 = 12.
As I said, correct me if I'm wrong.

What are the coordinates of the center of a circle whose equation is (x+1)^2+y^2=100?
Answer:
The center is (-1,0) and the radius is 10
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where the center is (h,k) and the radius is r
(x+1)^2+y^2=100
(x - -1)^2+(y-0)^2=10^2
The center is (-1,0) and the radius is 10
Answer:
radius = 10
center = (- 1, 0)
Step-by-step explanation:
eqn. of the circle = (x - h)^2 + (y - k)^2 = r^2
= (x + 1)^2 + y^2 = 100
(x - (-1))^2 + (y - 0)^2 =10^2
The center is (- 1, 0) and the radius is 10
