Answer:

When subtracting integers you have to change the sign of the second integer; When subtracting polynomials you have to change the sign of each term in the second polynomia. Then follow rules for addition of integers .

Hope this helps!

When you subtract polynomials, it is kind of like subtracting integers, because in both, you subtract normally. For example, 3xy - 2xy = 1xy. You have to subtract integers when you subtract polynomials

Assume that the playbook contains 9 passing plays and 15 running plays. The coach randomly selects 8 plays from the playbook. Wh

d1i1m1o1n [39]

<span>Answer = probability that he selects exactly 2,3,4 or 5 passing plays. prob that he selects exactly two passing plays = (8C2)*(9*8)* (15*14*13*12*11*10) /(26*28*.....19) where: 8C2 is the number of ways of choosing two slots out of 8 and prob that he selects first passing play = 9/26 prob that he select second passing play = 10/25 etc you can calculate the other three cases similarly and sum to obtain the answer.</span>

Find the range of allowable values based on a measure of 130 inches if the values can vary by 1.4%.

olganol [36]

Answer:

130 ± 1.82 inches i.e the range of the values is 128.18 inches to 131.82 inches.

Step-by-step explanation:

The range of values required here implies the values fall between the least and maximum values.

Since the values can vary by 1.4%, the range can be determined by:

1.4% of 130 = $\frac{1.4}{100}$ x 130

= 0.014 x 130

= 1.82

The addition or subtraction of 1.82 to/from 130 inches gives the required range.

i.e the range of allowable values = 130 ± 1.82 inches.

Thus,

130 - 1.82 = 128.18 inches

130 + 1.82 = 131.82 inches

The values falls between 128.18 inches to 131.82 inches.

Triangle N T M is shown. Angle N T M is a right angle. An altitude is drawn from point T to point U on side N M to form a right

stich3 [128]

Answer:

The value of y is 6 $\sqrt{3}$ units ⇒ 2nd answer

Step-by-step explanation:

In the attached figure

∵ ∠MTN is a right angle

∵ TU is the altitude of the triangle

- There are some rules in this triangle let us revise them

(NT)² = NU . NM
(MT)² = MU . MN
(TU)² = MU . NU
TM . TN = TU . MN

∵ NU = 9 units

∵ UM = 3 units

∵ MN = UM + NU

∴ MN = 3 + 9 = 12 units

- By using the 1st rule above

∴ (NT)² = 9 × 12

∴ (NT)² = 108

- Take a square root to both sides

∴ NT = $\sqrt{108}$

- Simplify the root

∴ NT = 6 $\sqrt{3}$ units

∵ NT is y

∴ y = 6 $\sqrt{3}$ units

The value of y is 6 $\sqrt{3}$ units
