Which shows the correct substitution of the values a,b,and c from the equation 0=4x^2+2x-1 into the quadratic formula below

lutik1710 [3]

Given quadratic equation : $0 = 4x^2+2x- 1$

Let us apply standard quadratic form $0=ax^2+bx+c$

We know, quadratic formula

$x = \frac{-b+-\sqrt{b^2-4ac}}{2a}$

a = 4

b = 2

c= -1

Now we plug in all the values in quadratic formula

$x = \frac{-b+-\sqrt{b^2-4ac}}{2a} \\ x = \frac{-2+-\sqrt{2^2-4(4)(-1)}}{2(4)}\\ x = \frac{-2+-\sqrt{18}}{8}$ .

<h3>The above one is the substitution of values of a,b,c in quadratic formula.</h3>

What is the approximate distance between point A and B? A(1,4),B(-2,-3)

nata0808 [166]

Answer:

√58 or 7.61 units

Step-by-step explanation:

Given points are:

A(1,4)

B(-2,-3)

The distance formula is used to find distance between two points.

The distance formula is:

$d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}} \\Putting\ the\ values\\d=\sqrt{(-2-1)^{2}+(-3-4)^{2}}\\=\sqrt{(-3)^{2}+(-7)^{2}}\\=\sqrt{9+49}\\=\sqrt{58}\\$

So the approximate distance is √58 or 7.61 units ..

A certain intelligence test has an N(100, 100) distribution. To see whether intelligence is inherited, tests are given to the el

Anettt [7]

Answer:

Follows are the solution to the given choices:

Step-by-step explanation:

In choice a:

$\to \mu = 100$

In choice b:

$\to \mu \neq 100$

In choice c:

$\to \ pop \ average=100 \\\\ \to \ variance \ of \ pop = 100 \\\\\to pop \ \ \sigma = \sqrt {(!00)} \\$

= 10

$z= \frac{\bar x - \mu}{ \frac{\sigma}{\sqrt(n)}}\\\\$

$=\frac{(105-100)}{\frac{10}{ \sqrt(16)}}\\\\=\frac{(5)}{ \frac{10}{4}}\\\\=\frac{5}{ \frac{5}{2}}\\\\= \frac{10}{5}\\\\=2$

$\to p==2\times (1- \ righttail)\\\\\to \ righttail\ \ p = \text{NORM.S.DIST(2,TRUE)}$

$=0.977249868$

$\therefore \\P=2 \times (1-0.9772)\\\\P=0.0455\\\\P$

Null hypothesis to dismiss

Alternate solution assumptions embrace

There is really no valid proof at the 5% stage that

Knowledge is legacy

In choice d:

Possibly information such as this reflect a sample population with such a true p = 0.0455 meaning in the hypothesis

u is around 100.

For the past 15 months, Frank recorded the cost of his monthly home heating bill and the corresponding average monthly temperatu

leonid [27]

The scatter plot shows that the heating bill will be about $95 for an average monthly temperature of 40°F.

<h3>What is a scatter plot?</h3>

It should be noted that a scatter plot uses dots to represent values for different numeric variables. In this case, the position of each dot on the horizontal and vertical axis shows the values for an individual data point.

From the complete question, the graph attached shows that the heating bill will be about $95 for an average monthly temperature of 40°F.

In conclusion, scatter plots are used to observe the relationships between variables.
