-21. A consumer products company is formulating a new shampoo and is interested in foam height (in mm). Foam height is approxima
ExtremeBDS [4]

Answer:

0.057

Step-by-step explanation:

To obtain the p value, we need to obtain the test statistic :

For a one sample test :

Test statistic is given by :

(xbar - μ) ÷ (σ/√(n))

(185 - 175) ÷ (20/√(10))

10 ÷ 6.3245553

Test statistic = 1.581

Qe used the Z distribution because we are working with the population standard deviation.

Using the Pvalue from test statistic calculator :

Pvalue obtained using the Pvalue from Z statistic calculator, we obtain ;

Pvalue = 0.0569

Find the vertex and axis of symmetry for f(x)=2x^2-1
vfiekz [6]
<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

<em><u>Solution:</u></em>

<em><u>Given is:</u></em>

f(x) = 2x^2 - 1

We have to find the vertex and axis of symmetry

<em><u>The general equation is given as:</u></em>

f(x) = ax^2 + bx + c

Comparing with given equation,

a = 2

b = 0

c = -1

<em><u>The axis of symmetry is given as:</u></em>

x = \frac{-b}{2a}

x = \frac{0}{2(2)}\\\\x = 0

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)

Use substitution to solve the system 5x-3y=23 2x+y=7
Viefleur [7K]
Because "y" is + in <span>2x+y=7, let's subtract 2x from both sides and end up with an expression for y:  y = 7 - 2x.  Substituting this into 5x - 3y = 23, 

5x - 3(7 - 2x) = 23.  Multiply out -3(7 - 2x):

5x - 21 + 6x = 23.  Combining 5x and 6x, 11x - 21 = 23, or 11x = 44.

Thus, x = 4.  Since y = 7 - 2x, subst. x = 4 results in the value of y:

y = 7 - 2(4) = 7 - 8 = -1.

The solution is (4,-1).</span>
