Answer:
[tex] \huge \boxed{x = 8}[/tex]
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
[tex]70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88[/tex]
Divide both sides by 11
[tex] \frac{11x}{11} = \frac{88}{11} \\ [/tex]
We have the final answer as
x = 8Hope this helps you
After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are as follows. P(soil | high-quality oil) = 0.20 P(soil | medium-quality oil) = 0.80 P(soil | no oil) = 0.20 How should the firm interpret the soil test? The probability of finding oil is good. Given the probability of finding good soil, the oil company is more likely to find oil. What are the revised probabilities?
Answer:
The revised probabilities are;
The probability of finding soil with oil = 0.8
The probability of finding soil with good oil = 0.16
The probability of finding medium quality oil = 0.64
Step-by-step explanation:
The given probability of finding soil with high quality oil, P(QO) = 0.20
The probability of finding soil with medium-quality oil, P(OM) = 0.80
The probability of finding soil with no oil, P(ON) = 0.2
Therefore, given that the probability of finding soil with no oil = 0.2, we have;
The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil
P(OP) = 1 - 0.2 = 0.8
Which gives;
The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;
P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16
The probability of finding good oil = 0.16
Similarly;
The probability of finding medium quality oil P(FM) = P(OM) × P(OP) = 0.8 × 0.8 = 0.64
Which gives the revised probability as follows;
The probability of finding soil with oil, P(OP) = 0.8
The probability of finding soil with good oil, P(FG) = 0.16
The probability of finding medium quality oil, P(FM) = 0.64.
Emilio throws a marshmallow into the air from his balcony. The height of the marshmallow (in feet) is represented by the equation h=−16t2+8t+48, where t is the time (in seconds) after he throws the marshmallow.
h= -16t^2+8t+48
Answer:
.18
Step-by-step explanation:
if ^2 is an exponent
(-16t*-16t)+8t+48
(258t+8t)+48
266t+48
48/266
.180
or .18

You put the problem into slooe-intercept form.
Slope = - 3/5, y-intercept = 5
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 5
Step-by-step explanation:
Assuming you require an equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{5}[/tex] and c = 5, thus
y = - [tex]\frac{3}{5}[/tex] x + 5 ← equation of line
is 5.67 A)rational B)Irrational C)whole D) natural E)integer

y − 3x = 4 slope intercept form plsssssssss
Answer:
y = 3x + 4
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b. We add - 3x to 4 to isolate the y.
Allen's score in a video game was changed by −55 points because he missed some targets. He got −11 points for each missed target. How many targets did he miss?
Answer:
Allen missed 5 targets.
Step-by-step explanation:
You divide -55 by -11 to find how many targets he missed. But when you divide, you have to remember that a negative divided by a negative is a positive, so the answer will be postitive.
-55/-11=5
What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4?
Oy-1=4(3-3)
Oy+3 = 4(x+1)
Oy+1=4(x+3)
Oy-3 = 4(2 - 1)
Answer:
The answer is y+3 = 4(x+1)Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
So we have
[tex]y + 3 = 4(x + 1)[/tex]

Are these two triangles similar???????!!!!!!! PLEASE HELP! I WILL GIVE BRAINILST AND MANY POINTS!
Answer:
yes the blue one is bigger but the green one is just smaller but if you multiply the sides by two it would be the same size so yeah they are similar
Step-by-step explanation:
Answer:
It's called Dilation when a triangle is the similar but only smaller, but as he said above, multiply the numbers by 2, you can't if they aren't numbers but if you do then it'll be the same size.

7k-10=-8-4(k+6)
Helpp
Answer:
k=-2
Step-by-step explanation:
7k-10=-8-4(k+6)
7k-10=-8-4k-24
7k-10=-32-4k
7k-10=-32-4k
11k-10=-32
11k=-22
k=-2
Step-by-step explanation:
7k-10= -8-4(k+6)
7k-10= -8-4k_24
7k+4k= -8-24+10
11k= -22
k= -22/11
k= -2
Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15. The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15.. What is the solution to the equation? x = 10 x = 12 x = 15 x = 30
Answer:
[tex] x = 12 [/tex]
Step-by-step explanation:
x = the quantity to find
This quantity added to ¼ of itself gives 15.
Thus, this problem can be represented as given above:
[tex] x + \frac{1}{4}x = 15 [/tex]
Solve for x
[tex] x + \frac{x}{4} = 15 [/tex]
[tex] \frac{4x + x}{4} = 15 [/tex]
[tex] \frac{5x}{4} = 15 [/tex]
Multiply both sides by 4
[tex] \frac{5x}{4}*4 = 15*4 [/tex]
[tex] 5x = 60 [/tex]
Divide both sides by 5
[tex] \frac{5x}{5} = \frac{60}{5} [/tex]
[tex] x = 12 [/tex]

find the sum of the first 25 multiples of 10.
Answer:
Step-by-step explanation: So the first 25 multiples of 10 are ,
10,10,10,10 ect, to 25 the sum of all of the numbers is 250 i hope this helped!!!
Answer:
3250
Step-by-step explanation:
First 25 multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 155
21 + 22 + 23 + 24 + 25 = 115
55 + 155 = 210
210 + 115 = 325
325 x 10 = 3250
Hope this helped!
