A plane flew for 2 hours at 467 mph (miles per hour) and 5 hours at 536. How far did the plane fly in miles

Archy [21]

Answer:

3614 miles

Step-by-step explanation:

Given data

A plane flew for 2 hours at 467 mph

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 467*2

Distance=934 miles

5 hours at 536

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 536*5

Distance=2680 miles

Total distance

=2680+934

=3614 miles

The price of fruits per kg are given below- Watermelon Rs 18.50 Cherry Rs 72 Grapes Rs 120.60 Apples Rs 78.40 Karan bought 412 k

Papessa [141]

Answer:

$X=-2.74*10^{-7}Rs$

Step-by-step explanation:

From the question we are told that:

Table for price per Kg

Watermelon Rs 18.50

Cherry Rs 72

Grapes Rs 120.60

Apples Rs 78.40

Karan Bought:

412 kg watermelon

1 kg 200g cherries

250 g grapes

134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

$\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))$

$\sum (P* W)=27374289.78$

Therefore the Amount of Money he gets back is

$X=500-\sum (P* W)$

$X=-2.74*10^{-7}Rs$

Therefore

He owes the shop keeper 2.74 million Rs

In a recent poll of 1100 randomly selected home delivery truck drivers, 26% said they had encountered an aggressive dog on the j

tankabanditka [31]

Answer:

d) 0.0132

Step-by-step explanation:

In a sample of size n, with proportion p, the standard error of the proportion is:

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

In this problem, we have that:

$p = 0.26, n = 1100$

$SE_{p} = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.26*0.74}{1100}} = 0.0132$

So the correct answer is:

d) 0.0132
