vegetable are ripe?

Answer:

Tomatoes = 39.5

Squash = 55.5

Step-by-step explanation:

T (tomatoes) = S - 16

S + T = 95

we plug it in now

S + (S - 16) = 95

2s = 95 + 16

2s = 111

s = 55.5??

hm. Let's go with it

T = 55.5 - 16

T = 39.5

39.5 + 55.5 = 95

I...guess?

How do you do inequalities

sineoko [7]

Answer:

See description below.

Step-by-step explanation:

An inequality is an equation with more than one solution and they use <, >, $\leq$ or $\geq$ . There are a number of ways to work with inequalities.

Solving: To solve inequalities in one variable, treat it just like an equation. Solve using inverse operations. If you divide or multiply by a -1 then be sure to flip the sign. For example, if you have > then it becomes <.

Graphing on a number line: To graph inequalities in one variable, use a number line. Plot a point on the number line with an open circle then an arrow pointing toward the solution set. If you have an equal to, you would shade in the open circle.

Solving: To solve inequalities in two variables, you need a system meaning more than one. You solve it like a system of equations by graphing.

Graphing: To graph inequalities with two variables, graph each in y=mx+b form using the y-intercept and slope. Connect the points with a dashed line unless equal to. Equal to inequalities have a solid line. To show the solution set, shade the side of the inequality which (x,y) points make it true. To find this, test a point by substituting into the inequalities.

Assume a significance level of alpha = 0.05 and use the given information to complete parts (a) and (b) below. Original claim

laiz [17]

Answer:

a

The correct option is B

b

The correct option is D

Step-by-step explanation:

From the question we are told that

The level of significance is $\alpha = 0.05$

The p-value is $p = 0.2761$

Considering question b

Given that the $p< \alpha$ then the null hypothesis is rejected

Considering question b

Given that the original claim is The standard deviation of pulse rates of a certain group of adult males is more than 11 bpm

Then the null hypothesis is $H_o : \sigma = 11$

The reason why the null hypothesis is write like this above is because a null hypothesis expression can not contain only a > or a < but only allows = $\le , \ and \ \ge$

and the alternative hypothesis is $H_a : \sigma > 11$

Now given that the null hypothesis is rejected, it mean that there is sufficient evidence to support original claim

Which set represents the same relation as the table below?

erik [133]

Answer:

A) { (0, 5), (4, 2), (6, 9), (9, 10)}

Step-by-step explanation:

From the table values, we can write the relation in coordinate form (x, f(x)).

The first value is x and the second value is f(x) in the coordinate.

Let's write the coordinates from the given table.

(0, 5), (4, 2), (6, 9), (9, 10)

Let's write the above coordinates in set form.

{ (0, 5), (4, 2), (6, 9), (9, 10)}

The set A is same relation as the given table.

Answer: A) { (0, 5), (4, 2), (6, 9), (9, 10)}

Hope you will understand the concept.

Thank you.

How many ways can three people be selected from a group of seven people if order<br> DOES matter?

spayn [35]

Answer:

210 ways

Step-by-step explanation:

The is a permution problem.

Formula for permutations of r things taken from n things is

$P(n,r) = \frac{n!}{(n - r)!}$

$\frac{7!}{(7 - 3)!} = \frac{7!}{4!} = 7*6*5 = 210$ ways

Solve and check the equation.<img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D%3D%5Cfrac%7B5x%7D%7B7%7D%20-43" id="TexFor

Y_Kistochka [10]

Answer:

x = 70

Step-by-step explanation:

Step 1: Simplify both sides of the equations.

$\frac{x}{10} = \frac{5x}{7}-43$
$\frac{1}{10}x=\frac{5}{7}x-43$

Step 2: Subtract 5/7x from both sides.

$\frac{1}{10}x- \frac{5}{7}x = \frac{5}{7}x - 43 - \frac{5}{7}x$
$\frac{-43}{70}x = -43$

Step 3: Multiply both sides by 70/(-43).

$\frac{-43}{70}x * \frac{70}{-43} = -43*\frac{70}{-43}$
$x = 70$

Step 4: Check if solution is correct.

$\frac{(70)}{10}=\frac{5(70)}{7} -43$
$7 = \frac{350}{7} - 43$
$7 = 50 - 43$
$7 = 7$

Therefore, x = 70.
