Answer:

2 , Real

Step-by-step explanation:

The quadratic equation is ,

⇒ 4x² - x - 4 = 0 .

Since it is a quadratic equation and has the highest degree of variable as 2 therefore it will have two solutions . For determining the nature of roots we will find the discriminant . The Discriminant of a quadratic equation in standard form of ax² + bx + c = 0 , is ,

⇒ D = b² - 4ac

⇒ D = (-1)² - 4 × 4 × (-4)

⇒ D = 1 + 64

⇒ D = 65 .

Since Discriminant is Greater than 0 , therefore the roots will be real .

Answer:

4= 0 is two one real solution.

Answer:

[tex]A=227.84\ inch^2[/tex]

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 5 inch

Hight, h = 12 m

Radius, r = d/2 = 2.5 m

We need to find the surface area of the cylinder. The formula for the surface area of the cylinder is given by :

[tex]A=2\pi rh+2\pi r^2\\\\A=2\times \dfrac{22}{7} \times 2.5\times 12+2\pi \times 2.5^2\\\\A=227.84\ inch^2[/tex]

So, the lateral surface area of the cylinder is equal to [tex]227.84\ inch^2[/tex].

Answer:

D) If WX = XY and XY = YZ, then WX = YZ.

Step-by-step explanation:

The transitive property states that if a=b and b=c, then a=c. So, if two different values equal to the same, separate value, then they are also congruent. The answer choice, d, represents this idea because WX and YZ both equal XY and are shown to be equal.

Answer:

OD) If WX = XY and XY = YZ, then WX = YZ.

Answer:2

Step-by-step explanation:

Answer:

a) The 95% confidence interval estimate of μ is (39.35, 42.5).

b) Second-year students tend to procrastinate more than first-year students

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 69 - 1 = 68

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 68 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.9955

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.9955\frac{6.85}{\sqrt{69}} = 1.65[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 41 - 1.65 = 39.35

The upper end of the interval is the sample mean added to M. So it is 41 + 1.65 = 42.65

The 95% confidence interval estimate of μ is (39.35, 42.5).

b. How does the confidence interval for the population mean score for second-year students compare to the confidence interval for first-year students of (35.447, 38.633)?

The confidence interval for second-year students had higher values both at the lower and the upper end of the interval, which means that they tend to procrastinate more than first-year students

Answer:

14

Step-by-step explanation:

The two triangles are similar

KN/KL = MN/JL

12/32 = (x+1)/(3x-2) multiply the fractions

36x-24 = 32x+32 export like terms to the same side

36x-32 = 32 + 24

4x = 56 divide both sides by 4

x = 14

Answer:

A) A dilation by a scale factor of 2, centered at the origin, followed by a 180° clockwise rotation about the origin.

Step-by-step explanation:

a dilation by a scale factor of 2, centered at the origin will double its size and move point A from (-2,2) to (-4,4). Then the clockwise rotation of 180° degrees will rotate the figure so that it's point A (now called point D) will be at (4,-4).

Answer:22215

Step-by-step explanation: got it from delta math

After 16 years Angel would have amount $22942 more money in his account than Jackson.

Compound interest is the interest you earn on interest. Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

For the given situation,

Investment of Jackson, p = $81000

Rate of interest, r = 6 1/2%

⇒ [tex]6.5\% = 0.065[/tex]

Interest is compounded monthly, so n = 12

Number of years, T = 16

Investment of Angel, p = $81000

Rate of interest, r = 7 1/8%

⇒ [tex]7.125\% = 0.07125[/tex]

Interest is compounded quarterly, so n = 4

Number of years, T = 16

The formula of amount in compound interest is

[tex]A=p(1+\frac{r}{n} )^{nT}[/tex]

Jackson's amount after 16 years,

⇒ [tex]A=81000(1+\frac{0.065}{12} )^{(12)(16)}[/tex]

⇒ [tex]A=81000(\frac{12.065}{12} )^{192}[/tex]

⇒ [tex]A=81000(1.0054)^{192}[/tex]

⇒ [tex]A=81000(2.8123)[/tex]

⇒ [tex]A=227798.13[/tex]

Angel's amount after 16 years,

⇒ [tex]A=81000(1+\frac{0.07125}{4} )^{(4)(16)}[/tex]

⇒ [tex]A=81000(\frac{4.07125}{4} )^{64}[/tex]

⇒ [tex]A=81000(1.0178)^{64}[/tex]

⇒ [tex]A=81000(3.0955)[/tex]

⇒ [tex]A=250739.62[/tex]

After 16 years, how much more money would Angel have in his account than Jackson is

⇒ [tex]250739.62-227798.13[/tex]

⇒ [tex]22941.49[/tex] ≈ [tex]22942[/tex]

Hence we can conclude that after 16 years Angel would have $22942 more money in his account than Jackson.
