Answer:

y = 9 1/3 or 8 if the first equation is 1/3x + 1/4y = 1.

Step-by-step explanation:

1/3x + 1/4y = 2

    2x - 3y = -30

Multiply the first equation by -6:

- 2x - 3/2y = -12  

Adding the last 2 equations:

-9/2 y = -42

y = -42 * -2/9

y = 9 1/3.

If the first equation is 1/3x + 1/4 y = 1

then y = -36 * -2/9

= 8.

butalik [34]

Answer:

0.95988 (Accuracy of the test )

Step-by-step explanation:

To determine the accuracy of this test we have to list out the given values

Prevalence rate of the disease = 0.3% = 0.003

sensitivity rate of the disease = 92% = 0.92

specificity rate for the test = 96% = 0.96

The accuracy of the test can be found using this equation

Accuracy = sensitivity * prevalence + specificity ( 1 - prevalence )

                = 0.92 * 0.003 + 0.96 ( 1 - 0.003 )

                = 0.00276 + 0.95712

                = 0.95988

Find the missing dimension of each prism.
Leto [7]

Given:

Volume of the prism = 60 in³

Breadth = 2.5 in

Height = 4 in.

To find:

The length of the prism.

Solution:

We know that, volume of a prism is

V=l\times b\times h

where, l is length, b is breadth and h is height.

Putting V=60, b=2.5 and h=4, we get

60=l\times 2.5\times 4

60=l\times 10

Divide both sides by 10.

\dfrac{60}{10}=l

6=l

Therefore, the missing dimension of the prism is 6 in.

Darina [25.2K]
This is all percentages so...
4/9 = 44%
2/7 = 29%
1/10 = 10%
Total = 83%
So 17% of 630 is left over which = 107
