The results of inspection of DNA samples taken over the past 10 days are given below. Sample size is 100.
ASHA 777 [7]

Answer:

The average defective rate  = .057

Step-by-step explanation:

Given -

Sample size n = 100

Day    -         1  2  3  4  5  6  7  8  9  10

Defectives -  7  6  6  9  5  6  0  8  9   1

The average defective rate is the no of defective in each day for past ten days

The average defective rate  =  \frac{\sum no\;  of \; effective \;  in\;  each\;  day}{no\; of \; day \times n}

                                               = \frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}

                                               = \frac{57}{1000}

                                               = .057

I need to find the value of x help needed
Oksi-84 [34.3K]

Answer:

x=33°

Step-by-step explanation:

Hi there!

We're given a triangle, with 2 known measures of angles in the triangle

54° and 93°

the other (unknown) value is x

the angles in a triangle add up to 180°

therefore, to find the value of x, we can add up the values of the 3 angles and set that to equal 180

54°+93°+x°=180°

add 54 and 93

147°+x°=180°

subtract 147 from both sides

x=33°

so the value of x is 33 degrees

Hope this helps!

In the figure below, if segment BC = 12 cm and segment AD = 2x + 4, then x = 5.
shtirl [24]
The answer would be false.

Since the figure above is a square, that would mean all sides are equal size. If x=5, that would make segment AD bigger than segment BC.
