There are two variables: time(dependent) and number of handbag(independent). Time changes as the number of hand bags changes.

Answer: Introduction to Functions Unit Test

No, The points are random

The time increases while the number of bags do too. The time is independent and the bags are dependent.

A. P (t)= (P-5)+0.05 (P-5)+1.05(P-5)

B.Pt=1.05(P-5)=1.05(15.50-5)=$11.03

Yes, the points make a straight line

Find the value of 4w +1 given that -3w-7=2.<br> Simplify your answer as much as possible.

ivolga24 [154]

Answer:

-11

Step-by-step explanation:

-3w - 7 = 2

-3w (- 7 + 7) = 2 + 7

-3w = 9

-3w/-3 = 9/-3

w = -3

4w + 1

4(-3) + 1

-12 + 1

-11

A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is th

maria [59]

The question is modelled as shown in the diagram below

We have the angle, 30° and we know the length of the side opposite the angles, 25000 feet. We are looking for the ground distance between the plane and the tower. We will use the trigonometry ratio of Tan

$tan(x)= \frac{opposite}{adjacent}$
$tan(30)= \frac{25000}{y}$
$y= \frac{25000}{tan(30)}$
$y=43301.27019$

The distance between the point directly beneath the plane and the tower is 43301.3 feet (rounded to 2dp)

You are dealt a hand of three cards, one at a time. Find the probability of each of the following. a) The first heart you get

boyakko [2]

Answer:

a) 0.145

b) 0.013

c) 0.783

d) 0.586

Step-by-step explanation:

a) there are always 52 cards in total, 13 hearts

Pa = 39/52 × 38/51 × 13/50 = 19266/132600 = 257/1700 =0.145

b) there are always 13 diamonds in a complete card

Pb = 13/52 × 12/51× 11/50 = 11/850 = 0.013

c) there are always 4 aces, and 48 that are not aces

Pc = 48/52 × 47/51 × 46/50 = 4324/5525 = 0.783

d) there are 13 hearts,to get at least one heart we have.

Pd = 1 - p

Where p is the probability of no hearts

p = 39/52 × 38/51 × 37/50 = 703/1700 = 0.414

Pd = 1 - 0.414

Pd = 0.586
