Answer: b)because near-critical paths could become critical paths with small delays in these activities

Explanation: Program evaluation and review technique(PERT) technique is used for management of the project .The organizing, maintenance,coordination of any task is done by this chart. The non-critical activities need to be observed carefully because they may create near-critical methods which can lead to complexity.

Other options are incorrect because not all activities are equally rather monitoring is done to avoid errors and slack can occur at any path . Small delays can be caused but not complete project can get delayed and there can be risk of complexity rather than being uncompleted.Thus, the correct option is option(b).

Where do you place the logical test argument in an JF function formula?

balandron [24]

Answer:

the first argument listed after IF

Explanation:

The Logical... argument in an IF function formula is always the first argument listed after IF. And the second option is the value to be printed if the logical...argument is true, and if it is false then the value mentioned as third argument is assigned, or printed. And the logical...argument never comes before the IF function formula. Hence, the right option is the first argument.

A drowsy cat spots a flowerpot that sails first up and then down past an open window. The pot is in view for a total of 0.50 sec

GaryK [48]

Answer:

2.342m

Explanation:

Given

Time = 0.5 s

Height of Window = 2m

Because the pot was in view for a total of 0.5 seconds, we can assume that it took the cat 0.25 seconds to go from the bottom of the window to the top

Using this equation of motion

S = ut - ½gt²

Where s = 2

u = initial velocity = ?

t = 0.25

g = 9.8

So, we have.

2 = u * 0.25 - ½ * 9.8 * 0.25²

2 = 0.25u - 0.30625

2 + 0.30625 = 0.25u

2.30625 = 0.25u

u = 2.30625/0.25

u = 9.225 m/s ------------ the speed at the bottom of the pot

Using

v² = u² + 2gs to calculate the height above the window

Where v = final velocity = 0

u = 9.225

g = 9.8

S = height above the window

So, we have

0² = 9.225² - 2 * 9.8 * s

0 = 85.100625 - 19.6s

-85.100625 = -19.6s

S = -85.100625/19.6

S = 4.342

If 4.342m is the height above the window and the window is 2m high

Then 4.342 - 2 is the distance above the window

4.342 - 2 = 2.342m

The CMOS battery located on a computer's motherboard allows for maintaining the correct time and date information stored in CMOS

siniylev [52]

Answer:

True

Explanation:

CMOS (complementary metal-oxide-semiconductor) is a chip which is placed on the motherboard in order to store the system date and time and this is powered by a CMOS battery which is housed inside this chip and is used to manage the date and time when the system is off.
This is a long lasting battery which can work till the life of a motherboard.
This battery is also used to maintain BIOS settings and hardware settings and BIOS uses it during the booting process in order to retrieve the stored information regarding the hardware or system date time.
CMOS chip is basically volatile and cannot retain settings information when the computer system powers off but the CMOS battery helps to maintain these setting just like system time and date when the computer gets shut down.

6. Write a C++ program to print the largest three elements in an array. <br>

jasenka [17]

Answer:

if (arr[i] > max) -> max3 = max2, max2 = max , max = arr[i]. else if (arr[i] > max2) -> max3 = max2, max2 = arr[i]. else if (arr[i] > max3) -> max3 = arr[i]. At the end of the loop, we will print all three values.
