2 answers:

7 0

Answer: The equation is given by: 9- 1/3x = 7
Step-by-step explanation:
Let the number be denoted by x.
Now, we are given a word phrase as follows one-third of a number less than nine is equal to seven.
Now this word phrase could be mathematically expressed as a equation by: one third of x is 1/3 x
And this number less than 9 is given by :

9- 1/3x

Now, this number is equal to 7.
I.e. we finally have:
9- 1/3x = 7

The weight of people in a small town in missouri is known to be normally distributed with a mean of 154 pounds and a standard de

ad-work [718]

If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:
$z=\frac{173-154}{29}=0.655$
Referring to a standard normal distribution table, and using z = 0.66, we find:
$P(\bar x\ \textless \ 173)=0.7454$
Therefore
$P(\bar x\ \textgreater \ 173)=1-0.7454=0.2546$
The answer is: 0.2546

Drag the tiles to the correct boxes to complete the pairs. Match each system of inequalities to the graph representing its solut

mojhsa [17]

The solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)

<h3>How to determine the solution to the systems?</h3>

The graph of the systems of inequalities is not given.

So, I would plot a new graph to answer this question.

The systems of inequalities are given as:

y − x > 1 and 2x + y ≤ 2

x + y ≥ -3 and 5x – y ≤ -3

2x – y ≤ -1 and x + 2y < 4

4x – 3y < 12 and x + 3y ≥ 6

Next, we plot these inequalities on a graph and write out the points of intersection.

From the attached graph, we have:

y − x > 1 and 2x + y ≤ 2 ⇒ (0.3, 1.3)

x + y ≥ -3 and 5x – y ≤ -3 ⇒ (-1, -2)

2x – y ≤ -1 and x + 2y < 4 ⇒ (0.4, 1.8)

4x – 3y < 12 and x + 3y ≥ 6 ⇒ (3.6, 0.8)

Hence, the solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)

In the recipe,3/4 cup of white sugar makes 8 slices of pie .if you want 48 slices of pie, how much white sugar do you need

Mashutka [201]

Hi!

We will solve this using proportions, like this:

3/4 cup for 8 slices of pie

x cup for 48 slices of pie

_______________________

x = ((3/4)*48)/8

x = (3*48)/(4*8)

x = 144/32

x = 4,5

You need 4 1/2 cups of white sugar for 48 slices of pie.

Hope this helps!

yulyashka [42]

Answer:

B. It makes the graph really narrow.

Step-by-step explanation:

$\displaystyle Y = A[X - H]^2 + K$

In the Vertex Formula, any fraction you store in for A will result in a vertical shrink, widening the graph, whereas any whole number you store in for A will result in a vertical stretch, narrowing the graph.

I am joyous to assist you at any time.

Write an equation or inequality to represent the scenario:

aniked [119]

<h3>The value of x is equal to 1.</h3><h3>6(x + 2) = 20x - 2</h3>

Distributive property.

6x + 12 = 20x - 2

Add 2 to both sides.

6x + 14 = 20x

Subtract 16x from both sides.

14 = 14x

Divide both sides by x.

x = 1
