Find all solutions to 4x^2 + 2x -2 = 1?

Answer:

Step-by-step explanation:

A

For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.

Similarly, second quartile (also called median) is approximately in mid of the data.

Third quartile (also called upper quartile)  has approx 75% in its left partition, and on its right lies approx 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.

Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

Answer:

Step-by-step explanation:

125-70 bonus points =55 points left.

55 divided by 5.5 per visit = 10 times to get a free movie ticket.

To verify it is correct:

10 visits x 5.5 points each = 55 points total

55 + 70 bonus points = 125 for a free ticket.

Answer:

10

Step-by-step explanation:

Let x= number of visits

5.5x+70=

125

subtract -70 from 70 and 125

5.5x=  55

divide both sides by 5.5

x=10

Answer:

Step-by-step explanation:

Each of the intercepts is found by setting the other variable to zero and solving for the intercept value.

x-intercept

  4x -5·0 +20 = 0

  x +20/4 = 0 . . . . . divide by the coefficient of x

  x = -5 . . . . . . . . . . add -5

The x-intercept point is (-5, 0).

__

y-intercept

  4·0 -5y +20 = 0

  y +20/-5 = 0 . . . . . divide by the coefficient of y

  y = 4 . . . . . . . . . . . add 4

The y-intercept point is (0, 4).

__

The perpendicular line is found by swapping the x- and y-coefficients, negating one of them. You want the leading coefficient positive, so the equation becomes ...

  5x +4y = (some constant)

The constant is chosen according to the point you want on the line. For a line through the origin, the constant is zero.

  5x +4y = 0 . . . . perpendicular line

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

2) Test Statistic = -1.44

3) Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Step-by-step explanation:

Given the data in the question;

Sample mean x" = 24,638

sample size n = 46

standard deviation σ = 5531

level of significance ∝ = 0.10

NULL and ALTERNATIVE HYPOTHESIS

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

TEST STATISTICS

Z = (x"-μ) / σ√n

we substitute

Z = (24,638 - 25,809) / (5531/√46)

Z = -1171 / 815.5

Z = -1.44

Test Statistic = -1.44

Now, from normal z-table;

P-value = P( Z < -1.44 ) = 0.0749

P-value = 0.0749

Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.

Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

n = 1/2 or .5

Step-by-step explanation:

4n + 3 = 10 -10n

14n = 7

n = 1/2 or .5

Hope this helps!

Answer:

n = -0.5

Step-by-step explanation:

4n + 3 = 5(2 - 2n)

First you multiply 2 and 2n by 5

4n + 3 = 10 - 10n

subtract 4n on both sides (meaning subtract 4n by itself on the left side of the equal sign and subtract 10n and 4n)

3 = 10 + 14n

Subtract 10 on both sides

-7 = 14n

Divide on both sides

Your answer should be n = -0.5 (or -0.5 = n)

Step-by-step explanation:

r = 8/3 units

h = 13 units

Volume of cone = (1/3) πr²h

                           [tex]= \frac{1}{3}* 3.14 * \frac{8}{3}* \frac{8}{3}*13\\\\= 96.76 cubic units[/tex]

If the radius of the base of the cone, r, is [tex] \frac{8}{3} [/tex] units and the height, h, is 13 units, what is the volume of the cone ?

[tex] \bullet [/tex] Radius of the base of the cone (r) is [tex] \frac{8}{3} [/tex] units.

[tex] \bullet [/tex] Height (h) of the cone is 13 units.

Volume of the cone.

We know,

Formula of volume of cone is [tex] \frac{1}{3} [/tex] πr²h

So, volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] (\frac{8}{3})² [/tex] × 13

= [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] \frac{8}{3} [/tex] × [tex] \frac{8}{3} [/tex] × 13

= [tex] \frac{22 \: × \: 8 \: × \: 8 \: × \: 13}{3 \: × \: 7 \: × \: 3 \: × \: 3} [/tex]

= [tex] \frac{18304}{189} [/tex]

= 96.85 cubic units.

Answer:

C. Y< 3

Step-by-step explanation:

The shaded part is less than 3.

Answer:

0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.

Step-by-step explanation:

For each 3-pointer shot, there are only two possible outcomes. Either the player makes it, or the player does not. The same is valid for free throws. This means that both the number of 3-pointers and free throws made are given by binomial distributions.

Since 3-pointers and free throws are independent, first we find the probability of making exactly 3 3-pointers out of 10, then the probability of making exactly 5 free throws out of 10, and then the probability that the player will make exactly 3 3-pointers and 5-free throws is the multiplication of these probabilities.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Probability of making 3 3-pointers out of 10:

The chances of a basketball player hitting a 3-pointer shot is 0.4, which means that [tex]p = 0.4[/tex]. So this is [tex]P(X = 3)[/tex] when [tex]n = 10[/tex].

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{10,3}.(0.4)^{3}.(0.6)^{7} = 0.21499[/tex]

Probability of making 5 free throws out of 10:

The probability of hitting a free-throw is 0.65, which means that [tex]p = 0.65[/tex]. The probability is [tex]P(X = 5)[/tex] when [tex]n = 10[/tex].

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{10,5}.(0.65)^{5}.(0.35)^{5} = 0.15357[/tex]

Calculate the probability that the player will make exactly 3 3-pointers and 5-free throws.

0.21499*0.15537 = 0.0334

0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.
