Answer:
x=16, z=91
Step-by-step explanation:
Answer:
x = 16° , z= 89°
Step-by-step explanation:
here's your solution
=> (11x -85)° = 91°. [ both are vertical angle]
=> 11x = 91° + 85°
=> 11x = 176°
=> x = 176°/11
=> x = 16°
now, 91° + z = 180° [ linear pair]
=> z = 180° - 91
=> z = 89°

Answers
Step-by-step explanation:
slope = 2-4/2-1 = -2
y - 2 = -2(x - 2)
y-2 = -2x +4
y = -2x + 6
Answer:
y = -2x + 6
Step-by-step explanation:
(y-4)/(2-4) = (x-1)/(2-1)
(y-4)/(-2) = x-1
y-4 = -2x +2
y = -2x + 6

Answer:
x ≈ 1.796322 . . . in all cases
Step-by-step explanation:
For Newton's method iteration, we like to use a function such that we are finding a zero of the function. Here, this means we want to rearrange the equation to ...
f(x) = x^3 -x -4
so that we are finding x for f(x) = 0.
The iterator is ...
next x = x - f(x)/f'(x) . . . . . where f'(x) is the first derivative
Many graphing calculators can accept the notation f'(x), so we do not actually have to determine the derivative algebraically. In the first attachment, we have used the function f1(x) to compute the next iteration value ("next x").
__
a) In the first attachment, we have used a math package to define the function, the iterator, and an accumulator of iteration values. The N[ ] function causes the display of 7 significant digits. Computations are performed to 30 significant digits. Starting values are the third argument from the right end of the expression doing the computation. They are 1, 6/10, 57/100.
It shows that it takes 6 iterations starting from x=1 to get to 6 decimal places of accuracy. The 7th iteration is computed so that we can compare the first 6 decimal places. The final iteration gives a value of x of 1.796322.
We know that Newton's method converges quadratically (from a close-enough starting point), so 4 good decimal digits in the 5th iteration can be expected to become 8 good decimal digits in the 6th iteration. That is, if two iterations agree in the first 3 decimal digits, then the second of those can generally be considered accurate to at least 6 decimal digits.
__
b) Starting from x=0.6, more iterations are required. The attachment shows that 6-decimal place accuracy is achieved in 13 iterations. More iterations are required because the starting point is closer to the function turning point, so initial iterations tend to diverge from the root.
__
c) Starting from x=0.57, 20 iterations are required. This starting point is on the wrong side of the turning point of the function, so the initial iteration sends the computation a significant distance in the wrong direction.
__
d) The graph and tangent lines are shown in the second attachment. Successively smaller starting values have tangents with successively smaller slopes.

There are 4 green marbles, 3 red marbles, and 7 yellow marbles in a bag. What is the probability of drawing 1st a green and 2nd a green marbles with replacement.
Answers
Answer:
4/14 x 4/14 x 4/14 x 4/14 = 256/38416
Step-by-step explanation:
There are 4 green marbles
3 red marbles
7 yellow marbles
Altogether = 4 + 3 + 7 = 14
Probability of picking a green marble 1st = 4/14
Probability of picking a green marble 2nd = 4/14
and you still have 2 more green marbles in the bag, so it will look like this:
4/14 x 4/14 x 4/14 x 4/14 = 256/38416
At a food truck, 1/8 of a whole pizza costs $2. In an hour, 6 ¼ pizzas were sold. How much money was made at the food booth in that hour?
Answers
9514 1404 393
Answer:
$100
Step-by-step explanation:
We assume you're interested in the revenue collected by the food truck.
6 1/4 pizzas = (6·4+1)/4 = 25/4 = 50/8 pizzas = 50×(1/8 pizza)
If each 1/8 pizza slice is sold for $2, then the revenue is ...
50 × $2 = $100 . . . . revenue from 6 1/4 pizzas
Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feet, and the diameters in inches, recorded from 31 felled trees.

(B) (0.396, 1.712.
(C) (0.423,1.685).
(D) (0.732. 1.376).
(E) (53.07.70.99).
Answers
Answer:
(B) (0.396, 1.712)
Step-by-step explanation:
From the information given;
Confidence Interval = 0.95
Significance Level [tex]= 1 - 0.95 = 0.05[/tex]
The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:
= [tex]( Beta ^- \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ), Beta^+ \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ))[/tex]
From the regression coefficient, the estimated value of beta^ = 1.054
[tex]= (1.054 - t_{29,0.025} *(0.322), 1.054 + t_{29,0.025}*(0.322))[/tex]
[tex]t_{229,0.025} = 2.0452\\\\ = \mathbf{(0.396, 1.712)}[/tex]

The 95% confidence interval for the population mean weight of a semi tracker tractor truck is ______________.
Answers
Answer:
(19228.737 ; 20771.263)
Step-by-step explanation:
Given that:
Sample size, n = 17
Sample mean, m = 20,000
Sample standard deviation, s = 1500
α = 95%
The confidence interval,
Mean ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Tcritical at α = 0.05 ; df = n-1 = 17 - 1 = 16 ; 2 - tailed test = 2.120
Margin of Error = 2.120 * 1500/sqrt(17) = 771.263
Lower boundary :
20,000 - 771.263 = 19228.737
Upper boundary :
20,000 + 771.263 = 20771.263
Confidence interval :
(19228.737 ; 20771.263)
