Answer:

(d) see below

Step-by-step explanation:

Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...

A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares

Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.

Taymoor is going to apply for two different jobs. He estimates that

Ostrovityanka [42]

Answer:

0.58

Step-by-step explanation:

The probability that Taymoor gets at least one job is a sum of probabilities of 3 events:

1.He gets Job 1 (P(1.yes)= 0.3) and doesn't get the job 2 (P(2.not)=1-0.4=0.6)

P(1.yes,2.not)=P(1.yes)*P(2.not)=0.3*0.6=0.18

2. He doesn't get job1 (P(1.not)= 1-03=0.7 ) and gets job2(P2.yes)=0.4)

P(1.not,2.yes)=P(1.not)*P(2.yes)=0.7*0.4=0.28

3. He gets job1 (P(1.yes)= 0.3 ) and gets job2(P2.yes)=0.4)

P(1.yes,2.yes)=P(1.yes)*P(2.yes)=0.3*0.4=0.12

The resulted probability is P(gets job)= 0.18+0.28+0.12=0.58

The savings in a bank account can be modeled using S = 1250e^0.45t, where t is the number of years the

morpeh [17]

Using the given exponential function, it is found that it will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.

<h3>Exponential function:</h3>

The <em>exponential function</em> that models the savings in the bank account is given by:

$S(t) = 1250e^{0.45t}$

In which t is the time in years that the money has been in the account.

The time to double from the initial amount deposited of $1250 is t for which S(t) = 2(1250) = 2500, hence:

$S(t) = 1250e^{0.45t}$

$2500 = 1250e^{0.45t}$

$e^{0.45t} = \frac{2500}{1250}$

$e^{0.45t} = 2$

$\ln{e^{0.45t}} = \ln{2}$

$0.45t = \ln{2}$

$t = \frac{\ln{2}}{0.45}$

$t = 1.5$

It will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.

In a survey of some farmers of a community, 70% of them are found cultivating rice, 60% cultivating wheat, 20% are not cultivati

yan [13]

Answer + Step-by-step explanation:

let R be the set of farmers cultivating rice.

let W be the set of farmers cultivating wheat.

let n be the total number of farmers.

i) Check the attachment.

ii) Card R∪W = Card R + Card W - Card R∩W

Note : Card R denotes the number of farmers cultivating rice.

$CardR\cup W=n-\frac{20}{100} n = \frac{80}{100} n$

$CardR=\frac{70}{100} n$

$CardW=\frac{60}{100}n$

$CardR \cap W=450$

Card R∪W = Card R + Card W - Card R∩W

$\Longleftrightarrow \frac{80}{100} n=\frac{70}{100} n + \frac{60}{100} n-450$

$\Longleftrightarrow \frac{50}{100} n=450$

$\Longleftrightarrow n= 2 \times 450 = 900$

iiI) the number of farmers who are cultivating rice only :

$900\times \frac{70}{100} -450=180$
