Problem Situation: Susan is making a large batch of salsa. She can spend no more than $30 on ingredients. She buys all of the in

gredients except for tomatoes for $6.50. Tomatoes cost $2 per pound. How many pounds of tomatoes, x, can she buy? Inequality That Represents This Situation: 30≥6.50+2x To solve the inequality, you can begin by solving the equation as shown. Drag a diagram to each row of the table to show which number line represents all of the solutions for the inequality and which number line represents all of the solutions for the problem situation.

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x------> the pounds of tomatoes

we know that

The inequality that represent the situation is

30\geq 6.50+2x

solve for x

Subtract  6.50 both sides

30-6.50\geq 2x

23.50\geq 2x

Divide by 2 both sides

23.50/2\geq x

Rewrite

x\leq 11.75\ pounds

so

<em>All the solutions for the inequality </em>

The interval ------> (-∞, 11.75]

All real numbers less than or equal to 11.75

In a number line is the shaded area to the left at x=11.75 (close circle)

see the attached figure N 1

<em>All the solutions for the problem situation </em>

The interval ------> (0, 11.75]

All real numbers greater than zero and less than or equal to 11.75

In a number line is the shaded area between the number zero (open circle) and the number x=11.75 (close circle)

see the attached figure N 2

Vinil7 [7]

Answer:

The 95% confidence interval for the difference between the proportion of women who drink alcohol and the proportion of men who drink alcohol is (-0.102, -0.014) or (-10.2%, -1.4%).

Step-by-step explanation:

We want to calculate the bounds of a 95% confidence interval of the difference between proportions.

For a 95% CI, the critical value for z is z=1.96.

The sample 1 (women), of size n1=1000 has a proportion of p1=0.494.

p_1=X_1/n_1=494/1000=0.494

The sample 2 (men), of size n2=1000 has a proportion of p2=0.552.

p_2=X_2/n_2=552/1000=0.552

The difference between proportions is (p1-p2)=-0.058.

p_d=p_1-p_2=0.494-0.552=-0.058

The pooled proportion, needed to calculate the standard error, is:

p=\dfrac{X_1+X_2}{n_1+n_2}=\dfrac{494+552}{1000+1000}=\dfrac{1046}{2000}=0.523

The estimated standard error of the difference between means is computed using the formula:

s_{p1-p2}=\sqrt{\dfrac{p(1-p)}{n_1}+\dfrac{p(1-p)}{n_2}}=\sqrt{\dfrac{0.523*0.477}{1000}+\dfrac{0.523*0.477}{1000}}\\\\\\s_{p1-p2}=\sqrt{0.000249+0.000249}=\sqrt{0.000499}=0.022

Then, the margin of error is:

MOE=z \cdot s_{p1-p2}=1.96\cdot 0.022=0.0438

Then, the lower and upper bounds of the confidence interval are:

LL=(p_1-p_2)-z\cdot s_{p1-p2} = -0.058-0.0438=-0.102\\\\UL=(p_1-p_2)+z\cdot s_{p1-p2}= -0.058+0.0438=-0.014

The 95% confidence interval for the difference between proportions is (-0.102, -0.014).

What is the product of 4 2/3 and 11 1/4
mihalych1998 [28]

First you have to get rid of the mixed numbers, so multiply the whole numbers with the denominators and add the numerators so that way you get:

14/3 times 45/4....then cross simplify if possible and finally you can multiply the numerators and the denominators...

7/1 times 15/2 = 105/2....simplify it and get: 52 1/2
