Answer:

Interest earned = \$3915.30

Step-by-step explanation:

I=PRT (I = interest, P = principal, T = time)

I = 65255\times 0.03 \times2

=\$3915.30

∴ Gabrielle earns \$3915.30 in 2 years.

Hope this helps :)

Both triangles area:
4.2 x 8.2 = 34.44

you don’t need to divide by two cause there’s two triangles anyways.

also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)

rectangle:
4.2 x 5.3 = 22.26

the total area is 56.7cm squared

Answer:

The sample size is  n  = 36

Step-by-step explanation:

From the question we are told that

   The sample standard deviation is  s =  1.5

  The mean difference of the two groups is  \=x _ 1 - \=x_2 =  1

   The standard error is  SE =  \frac{ \= x_1 - \= x_2}{4}

=>                                      SE =  \frac{1}{4}

Let assume that the confidence level is 95% hence the level of significance is  

   \alpha = (100-95)\%

=> \alpha = 0.05

So the critical value of  \frac{\alpha }{2} obtained from the normal distribution table is

     Z_{\frac{\alpha }{2} } = 1.96

Generally the margin of error is mathematically evaluated as

     E =  Z_{\frac{\alpha }{2} } * SE    

   E =  1.96 * \frac{1}{4}

    E = 0.49

Generally the sample size is mathematically represented as

  n =[ \frac{Z_{\frac{\alpha }{2}  * s^2}}{E}]^2

=> n  = [\frac{1.96 * 1.5}{0.49} ]^2

=> n  = 36

\frac{3}{4} \times 2 =
suter [353]

To multiply two fractions, you simply multiply numerators and denominators together.

2 can be read as the fraction 2/1

So, the multiplication is

\dfrac{3}{4} \times \dfrac{2}{1} = \dfrac{3\times 2}{4 \times 1} = \dfrac{6}{4} = \dfrac{3}{2}
