Tyrone’s hourly wage is $18 and his net pay is 72% of his earnings. Tyrone spends about $1,800 on his monthly expenses. If Tyron
White raven [17]

Answer:

Step-by-step explanation:

The answer is

72% of his earnings is $18x 72 / 100 = $12.96

Tyrone works 40 hours per week

in one month

he works 40*4=160 hours

so 1 hour is for $12.96 net

160 hours for x=?

x=$2073.6

his total monthly cash inflow  is $2073.6 - $1,800=$273.6

a jet bomber traveling 500 mph arrived over its Target at the same time as its fighter jet escorted which left the same fate 2.5
vlada-n [284]

Since the jet bomber arrived over its Target at the same time as its fighter jet escorted, it took the jet bomber 0.34 h to reach the target.

<h3 />

To find the number of hours, we need to solve simultaneous equations.

<h3>What are simultaneous equations?</h3>

Simultaneous equations are pair of equations which contain two unknowns.

<h3>How to calculate the number of hours the bomber jet took off?</h3>

Let

  • D = distance travelled by both bomber jet and fighter jet.
  • t = time bomber jet took off
  • v = speed of bomber jet.
  • T = time fighter jet took off and
  • V = speed of fighter jet.

So, D = vt

D = 500t  (1)

Also, D = VT

D = 60T  (2)

Since  jet bomber traveling 500 mph arrived over its Target at the same time as its fighter jet escorted which left the same fate 2.5 hours after the bomb took off.

T = t + 2.5

So, D = 60(t + 2.5)  (3)

<h3>The required simultaneous equations</h3>

D = 500t  (1)

D = 60(t + 2.5)  (3)

Equating equations (1) and (3), we have

500t = 60(t + 2.5)

500t = 60t + 150

500t - 60t = 150

440t = 150

t = 150/440

t = 15/44

t = 0.34 h

So, it took the jet bomber 0.34 hours to reach the target.

Wildlife biologists inspect 153 deer taken by hunters and found 42 of them carrying Lyme disease ticks. Calculate and interpret
Tamiku [17]

Answer:

90 Confidence Interval for the proportion = [ 0.216,0.334]

Step-by-step explanation:

The confidence interval for proportion formula =

p ± z × √p(1 - p)/n

Where p = x/n

x = 42

n = number of samples = 153

p = 42/153

p = 0.2745098039 ≈ 0.275

z = z score of 90% confidence interval = 1.645

Confidence interval =

0.275 ± 1.645 × √0.275 - ( 1 - 0.275)/153

= 0.275 ± 1.645 × √0.0013031046

= 0.275 ± 0.0593820985

Confidence Interval

= 0.275 - 0.0593820985

= 0.2156179015

≈ 0.216

= 0.275 + 0.0593820985

= 0.3343820985

≈ 0.334

90 Confidence Interval for the proportion = [ 0.216,0.334]
