To find the money you make, take: 

x(1 (+ or -) % interest rate) * Time


So in this case, it would be:

3800(1+0.04)(1) = Ans
and
3800(1+0.07)(1) = Ans

Assumably, combining those totals would give you $218. If you take the total of 3800(1+0.04)(1), subtract that from $218.

218 - (3800(1+0.04)(1)) = Your Answer

Find the value of y in the given triangle
Andre45 [30]

Given:

In the given triangle,

With respect to y, Perpendicular = 10 cm and Base = 8 cm

To find the value of y.

Formula

By Trigonometric Ratio we get,

tan\theta = \frac{Perpendicular}{Base}

Now,

Putting the values of perpendicular and base we get,

tan\theta = \frac{10}{8}

or, \theta = tan^{-1} (\frac{10}{8})

or, \theta = 51.34 ^\circ

Rounding off to the nearest tenth, we have;

\theta = 51.3 ^\circ

Hence,

The value of y is 51.3°.

Students get two grades for a test in an introductory psychology course: a letter grade, and a numerical equivalent (weighted va
vlabodo [156]

Answer:

Average grade for this test = 1.85

Step-by-step explanation:

Given that number of students receiving respective grade scores are : 11, 18, 52, 13, 6

Then total number of students = 11 + 18 + 52 + 13 + 6 = 100

Sum score obtained by total students

= 11F + 18D + 52C + 13B + 6A

= 11(0) + 18(1) + 52(2) + 13(3) + 6(4)

= 0 + 18 + 104 + 39 + 24

= 185


Now average grade for this test is given by 185/100 = 1.85

Hence final answer is 1.85.

Find the Slope. (4, 4) (2, 3)<br> please and thanks
Dmitriy789 [7]

Answer: its m= 1/2

Step-by-step explanation:$\mathrm{Slope\:between\:two\:points}:\quad\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$Slope between two points:    Slope=

y2−y1

x2−x1

$\left(x_1,\:y_1\right)=\left(2,\:3\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)$(x1, y1)=(2, 3), (x2, y2)=(4, 4)

$m=\frac{4-3}{4-2}$m=

4−3

4−2

$\mathrm{Refine}$Refine

$m=\frac{1}{2}$m=

1

2

Examples

$slope\:3x+3y-6=0$slope 3x+3y−6=0

$slope\:f\left(x\right)=2x-1$slope f(x)=2x−1

$slope\:\left(-1,\:1\right),\:\left(-2,\:-3\right)$slope (−1, 1), (−2, −3)

$slope\:\left(-1,\:-2\right),\:\left(1,\:2\right)$slope (−1, −2), (1, 2)

$slope\:\left(0,\:-4\right),\:\left(-1,\:-7\right)$slope (0, −4), (−1, −7)

$slope\:\left(-4,\:2\right),\:\left(0,\:3\right)$slope (−4, 2), (0, 3)
