A clothing store has a going-out-of business sale. They are selling pants for $8.99 and shirts for $3.99. You can spend as much
astraxan [27]

Answer:

Let x represents the number of pants and y represents the number of shirts.

As per the statement:

Since, a clothing store are selling pants for $8.99 and shirts for $3.99

then;

total number of Pants cost is, $8.99x and total number of Shirt cost is, $3.99

Also, it is given that: You can spend as much as $60 and want to buy at least two pairs of pants.

then, we have the equation of inequality;

8.99x + 3.99y \leq 60 ;......[1]         where x, y are natural number.

x-intercept:

Substitute the value y= 0  in [1] and solve for x;

8.99x + 3.99(0) \leq 60

8.99x \leq 60

Simplify:

x \leq 6.667

Since, x is in natural number;

x \leq 7

Similarly.

For y-intercept:

Substitute the value x= 0  in [1] and solve for x;

8.99(0) + 3.99y \leq 60

3.99y \leq 60

Simplify:

y \leq 15.037

y \leq 15

Therefore, we have

8.99x + 3.99y \leq 60 ;

2\leq x\leq 7 and  0\leq y\leq 15

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. How many pounds of chocolate costing $13.20 pe
Stells [14]

Answer:

13lbs

Step-by-step explanation:

x = number of pounds of chocolate/lbs

13.20(x) + 3.90(10) = 9.16(x + 10)

13.2x + 39 = 9.16x + 91.6 (x100)

1320x + 3900 = 916x + 9160

404x = 5260

x = 1315/101 = 13.0198.... ⇒ 13lbs

A drug company is testing a new drag which is supported to reduce blood pressure. From the nine people who are used as subjects,
Pie

Answer:

The 95% confidence interval for the mean change in blood pressure, \bar{x}, is 1.744 < \bar{x} < 2.816

Step-by-step explanation:

The parameters given are;

The number of people in the sample, n = 9

The average drop in blood pressure, \bar{x} = 2.28 points

The standard deviation, σ = 0.82

The confidence level = 95%

The formula for confidence interval with a known mean is given as follows;

CI=\bar{x}\pm z_{\alpha/2} \dfrac{\sigma}{\sqrt{n}}

Where:

z_{\alpha/2} = z - score at 95% confidence level = 1.96

We therefore have;

CI=2.28 \pm 1.96 \times \dfrac{0.82}{\sqrt{9}}

Which gives the 95% confidence interval for the mean change in pressure, \bar{x}, is given as follows;

1.744 < \bar{x} < 2.816
