solving eqn 1st

<u>x</u><u> </u>=<u>2</u>

y. 3

3x=2y

x =<u>2</u><u>y</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>3

again putting the value of y in eqn 1st

x= <u>2</u><u>y</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>3

x= <u>2</u><u>×</u><u>9</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>3

x=<u>1</u><u>8</u>

<u> </u><u> </u><u> </u><u> </u>3

x =6

now,

solving, eqn 2nd

<u>y</u><u> </u>= <u>3</u>

12. 4

4y =36

y=<u>3</u><u>6</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>4

y=9

hence,

the value of x =6 and y= 9.

hope it help u.

Problem PageQuestion Calcium levels in people are normally distributed with a mean of mg/dL and a standard deviation of mg/dL. I
SIZIF [17.4K]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The  calcium level that is the borderline between low calcium levels and those not considered low is  c = 8.68

Step-by-step explanation:

From the question we are told that

    The mean is  \mu =  9.5\  mg/dL

     The standard deviation \sigma =  0.5 \ mg/dL

    The proportion of the population with low calcium level is  p =5% = 0.05

Let X be a X random calcium level

  Now the  P(X < c) = 0.05

Here P denotes probability

        c is population with calcium level at the borderline

  Since the calcium level is normally distributed the z-value is  evaluated as

    P(Z < \frac{c - \mu}{\sigma } ) = 0.05

The critical value for 0.05 from the standard normal distribution table is

       t_{0.05} = -1.645

=>    \frac{c - \mu}{\sigma }  =  -1.645

substituting values

       \frac{c - 9.5}{0.5 }  =  -1.645

=>    c - 9.5 =  -0.8225

=>     c = 8.68
