Answer:

3 men = Rs. 6000 = 4 days

Step-by-step explanation:

→ Find how much 1 man make in 3 days

1 man = Rs. 1500 = 3 days

→ Find how much he makes in 1 day

1 man = Rs. 500 = 1 day

→ Find how much one man can make in 4 days

1 man = Rs. 2000 = 4 days

→ Find how much 3 men will make

3 men = Rs. 6000 = 4 days

Can someone help me out?

NISA [10]

Step-by-step explanation:

does this mean the sale price includes the tax already ?

then we need to find 13% of the original price before taxes.

that would be done by saying that $101.94 are actuality 113% of the original price (original price = 100%, and then 13% are added).

101.94 = 113%

1% = 101.94/113

13% = 101.94 × 13/113 ≈ $11.73

that means it of the total sales price of $101.94, $11.73 would be the included taxes.

but if this means that 101.94 = 100% of the original price before taxes, we need to calculate the 13% based on that

101.94 = 100%

1% = 101.94/100

13% = 101.94 × 13/100 ≈ $13.25

and then the total price to be paid is

101.94 + 13.25 = $115.19

Suppose a polling agency reported that 44.4% of registered voters were in favor of raising income taxes to pay down the nationa

g100num [7]

Answer:

95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.

(0.414 ,0.474)

Step-by-step explanation:

Step(i):-

Given sample proportion

p⁻ = 44.4 % = 0.444

Random sample size 'n' = 1049

Given margin of error for 95% confidence level = 3 % = 0.03

Step(ii):-

95% of confidence interval for the proportion is determined by

$(p^{-} - Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} } , p^{-} + Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} })$

we know that

Margin of error for 95% confidence level is determined by

$M.E = Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-}) }{n} }$

Step(iii):-

Now

95% of confidence interval for the proportion is determined by

$(p^{-} - M.E, p^{-} + M.E)$

Given Margin of error

M.E = 0.03

Now 95% of confidence interval for the proportion

$(0.444 - 0.03, 0.444+ 0.03)$

(0.414 ,0.474)

Conclusion:-

95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.

(0.414 ,0.474)

A mother gives birth to a 9 pound baby. every 4 months, the baby gained 2 pounds. if x is the age of the baby in months, then y

chubhunter [2.5K]

For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:

slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.

The equation of the line would be y = 0.5x + 9
