Answer:
The measure of angle BED is 82°
Step-by-step explanation:
The angles of a triangle, all together, equal 180°.
Angle B and D are the same and angle B is 49° so angle D is also 49°.
You add 49 to 49 which equals 98, and subtract 98 from 180 to find out what angle E is.

When the community is ordinary or a biosensor, a normal distribution could be calculated for the dependent variable. Data shows chi-squared distributions of n-1 degrees - of - freedom about the dependent variable.
Chi-square was its precise outcome for the data set, while chi-square is a close estimate for non-normal information. So, we should also calculate CI for uncommon information. Throughout the case of an outlier, however, data refers to non because as mean tends to move in a skewed direction to the outer surface.
The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate the maximum error in the calculated area of the disk. (Round your answer to two decimal places.) cm2 (b) What is the relative error
Answers
Answer:
9.60πcm²
Step-by-step explanation:
Area of circular disk, A = πr²
Differntiate A with respect to r
dA/dr = π * (2r^(2-1)) /(2-1) + C
dA/dr = π * 2r/1
dA/dr = 2πr
dA = 2πr * dr
dA = 2πrdr
dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm
dA = 2π * 24 * 0.2
dA = 9.60πcm²

[tex]y = 130 + 45x[/tex]
Step-by-step explanation:
Given
[tex]Base = 130[/tex]
[tex]Monthly = 45[/tex]
Required
The cost for x months
Represent this cost with y.
So:
[tex]y = Base + Monthly * x[/tex]
[tex]y = 130 + 45 * x[/tex]
[tex]y = 130 + 45x[/tex]

Answer:
[tex]y = \frac{1}{6}x - 4[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
[tex]y = \frac{1}{8}x[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
[tex]y = 12x - 9[/tex]
Step-by-step explanation:
Required
Represent in gradient intercept form
This means that the equation be in form: [tex]y = mx + c[/tex]
Solving (a): [tex]3y = \frac{1}{2}x - 12[/tex]
Divide through by 3
[tex]\frac{3y}{3} = \frac{1}{3*2}x - \frac{12}{3}[/tex]
[tex]y = \frac{1}{6}x - 4[/tex]
Solving (b): [tex]5x = 10y - 20[/tex]
Make y the subject
[tex]10y = 5x + 20[/tex]
Divide through by 10
[tex]y = \frac{5x}{10} + \frac{20}{10}[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
Solving (c): [tex]x = 8y[/tex]
Make y the subject
[tex]8y= x[/tex]
Divide through by 8
[tex]y = \frac{1}{8}x[/tex]
Solving (d): [tex]\frac{1}{2}x = 3y - 2[/tex]
Make y the subject
[tex]3y = \frac{1}{2}x+ 2[/tex]
Divide through by 3
[tex]y = \frac{1}{2*3}x+ \frac{2}{3}[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
Solving (d): [tex]\frac{2}{3}y - 8x = -6[/tex]
Make y the subject
[tex]\frac{2}{3}y = 8x -6[/tex]
Divide through by 3/2
[tex]\frac{3}{2} * \frac{2}{3}y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * 8x -\frac{3}{2} * 6[/tex]
[tex]y = 3 * 4x - 3 * 3[/tex]
[tex]y = 12x - 9[/tex]

Step-by-step explanation:

340 quarters1020 dimes1031 nickels2062 penniesStep-by-step explanation:
x is the number of quarters
__
a) d = 3x . . . . . . the number of dimes is 3 times the number of quarters
b) n = d + 11 = 3x +11 . . . . there are 11 more nickels than dimes
c) p = 2n = 2(3x +11) = 6x +22 . . . . there are twice as many pennies as nickels
d) The total number of coins is ...
x + d + n + p = 4453
x + (3x) +(3x +11) +(6x +22) = 4453
13x +33 = 4453
13x = 4420
x = 4420/13 = 340 . . . . number of quarters collected
3x = 1020 . . . . . . . . . . . .number of dimes collected
1020 +11 = 1031 . . . . . . . number of nickels collected
2·1031 = 2062 . . . . . . . . number of pennies collected
There were 340 quarters, 1020 dimes, 1031 nickels, and 2062 pennies collected.
