Total pounds of candy you received = Pounds of candy received from Grandmother + Pounds of candy received from Sister + Pounds of Candy received from Best Friend

Add them all up to find the total you received.

Total pounds of candy you received = 1/4 + 1/2 + 1/8
= 2/8 + 4/8 + 1/8 = 7/8 Pounds

When changing the denominator of a fraction, always make sure to change the numerator proportionately as well. For 1/4, since you wish to change the denominator to 8 (which is the largest denominator in the group), and since 8 is equal to 4 × 2, the numerator will also have to be multiplied by 2 (I.e. 1 × 2). This will give you 2/8.

Hope this helps! :)

Margarita [4]

Answer:

A

   The  correct option is B

B

   t =  0.6093

C

 p-value  =  0.27116

D

The  correct option is  D

Step-by-step explanation:

From the question we are told that

    The  sample size is  n  =  232

    The  number that developed  nausea  is X =  50

    The population proportion is  p  =  0.20  

 

The  null hypothesis is   H_o : p  =  0.20

The  alternative hypothesis is  H_a :  p > 0.20

Generally the sample proportion is mathematically represented as

     \r p  =  \frac{50}{232}

     \r p  =  0.216

Generally the test statistics is mathematically represented as

 =>           t =  \frac{\r p  -  p }{ \sqrt{ \frac{p(1- p )}{n} } }

=>           t =  \frac{ 0.216 - 0.20 }{ \sqrt{ \frac{ 0.20 (1- 0.20 )}{ 232} } }

=>        t =  0.6093

The  p-value obtained from the z-table is

       p-value  =  P(Z >  0.6093) =  0.27116

  Given that the  p-value >  \alpha  then we fail to reject the null hypothesis

Graph the function f(x) = 1/2(2)^x
xxMikexx [17]

Answer; Down

Step-by-step explanation:The graph of the squaring function has the shape of a parabola that opens up. Its vertex is at (0,0). The graph of F(x) = (1/2)x^2 has the same shape, but is compressed vertically by a factor of (1/2).

EXPERT HELP I'LL GIVE BRAINLIEST:
ICE Princess25 [194]

Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)
