Soulotion to equation if y is =15 when x=2 ,find y when x=8
skelet666 [1.2K]

Answer:

The value of y for x = 8 is 60  .

Step-by-step explanation:

Given expression as :

For x = 2  , y = 15

Let the equation be written with constant k'

So, y = k x

Or, k = \dfrac{y}{x}

∴   k =  \dfrac{15}{2}

<u>Now, again </u>

For x = 8

equation can be written as

   y = k x

Or,  y =  \dfrac{15}{2} × 8

Or,  y = \frac{15\times 8}{2}

∴    y = 15 × 4

I.e  y = 60

Hence The value of y for x = 8 is 60  . Answer

Find the probabilities for a standard normal random variable Z.
vampirchik [111]

Answer:

Step-by-step explanation:

find the attachment showing std normal curve symmetrical about y axis.

Equal probabilities on either side of the mean thus the total probability to the right of mean is 0.50

From the table we can find that

a) P(Z>2.5) = 0.5- area lying between 0 and 2.5

= 0.5-0.4938 =0.0062

b) P(1.2<z<2.2) = F(2.2)-F(1.2)

= 0.9861-0.3849

=0.6012

padilas [110]
If you would like to know the equation that shows the number of teaspoons of sugar needed to make x candy bars, you can calculate this using the following steps:

2.5 teaspoons of sugar ... 1 candy bar
y teaspoons of sugar = ? ... x candy bars = ?

2.5 * x = 1 * y
2.5 * x = y
y = 2.5 * x

The correct result would be <span>y = 2.5 * x.</span>
