solve for the value of p​

Answers

Answer:

43°

Step-by-step explanation:

p + 7° + 3p+ 1° = 180° ( Being linear pair)

4p + 8° = 180°

4p = 180° - 8 °

4p = 172°

p = 172° / 4

p = 43°

Answer:

the future value is $5,750.01

Step-by-step explanation:

The computation of the future value is shown below;

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $5,000 × (1 + 0.035 ÷ 12)^4 × 12

= $5,000 × (1 + 0.2916%)^48

= $5,750.01

Hence, the future value is $5,750.01

(in order) 196, 198, 248, 276, 289, 319, 349, 379  there are eight numbers.

--------------------------------------------------------------------------------------

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

= 223 (first quartile)

--------------------------------------------------------------------------------------

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

(319 + 349) ÷ 2

= 668/2

= 334 (third quartile)

Find the value of y.

Answers

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3

A sportswriter wishes to see if a football filled with helium travels farther, on average, than a football filled with air. To test this hypothesis, the writer uses 18 male subjects, randomly divided into two groups of 9 subjects each. Group 1 kicks a football filled with helium to the recommended pressure, while Group 2 kicks a football filled with air to the same pressure. The sample mean yardage for Group 1 was barx2 = 30 yards with a standard deviation of s1 = 8 yards. The mean yardage for Group 2 was barx2 = 25 yards with a standard deviation of s2 = 6 yards. Assume that the two groups of kicks are independent. Let μ1 and μ2 represent the mean yardage we would observe for the entire population represented by the volunteers if all members of this population kicked, respectively, a helium-filled football and an air-filled football. Let σ1 and σ2 be the corresponding population standard deviations. Assuming two-sample t procedures are safe to use, what is a 99% confidence interval for μ1 – μ2?
A) 4 ± 7.7 yards.B) 4 ± 11.2 yards.C) 4 ± 4.7 yards.D) 4 ± 6.2 yards.

Answers

Answer:

5 ± 9.74

Step-by-step explanation:

Confidence interval, two - sample, t procedure ;

μ1 - μ2 = (x1 - x2) ± Tcritical*S

S = sqrt[(s1²/n1) + (s2²/n2)]

n1 = 9 ; n2 = 9 ; s1 = 8 ; s2 = 6 ; x1 = 30 ; x2 = 25

S = sqrt[(8^2/9) + (6^2/9)]

S = sqrt[11.111111]

S = 3.333

Tcritical at 99% confidence interval

df = 18 - 2= 16

Tcritical = 2.92

(30 - 25) ± 2.92*(3.333)

Answer:

130.25 ft.

Step-by-step explanation:

The semi circle has a length 1/2 of the circumference of the circle with a diameter of 25

C = πd = 3.14(25)

So, the semi circle has a length = 1/2(3.14)25) = 39.25

The distance for the rectangle = 33 + 25 + 33 = 91

Therefore, the total perimeter = 91 + 39.25 = 130.25

The amount of a radioactive substance remaining as it decays over time is A = A0(0.5)t/h ,where a represents the final amount
Ao represents the original amount, t represents the number of years, and h represents the half-life of the sibstance.
The half-life of the radioactive isotope carbon-14 is 5,730 years. Approximately how many years will it take a 50-gram mass of
carbon-14 to decay to 5 grams?

Carbon-14 will take 19,035 years to decay to 10 per cent.

What is the time of decay?

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_oe^{-\lambda t}[/tex]

Where:

No  = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex]    = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]t_{1/2}=\dfrac{Ln(2)}{\lambda}[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\lambda =\dfrac{ln(2)}{t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\lambda =\dfrac{ln(2)}{5730}[/tex]

[tex]\lambda[/tex] = 0.00012097

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_oe^{-0.00012097t}[/tex]

We need to calculate the time required for the original amount to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=-N_oe^{-0.00012097t}[/tex]

Simplifying:

[tex]0.10=e^{0.00012097t}[/tex]

Taking logarithms:

ln(0.10) = -0.00012097t

Solving for t:

[tex]t=\dfrac{Log0.10}{-0.00012097}[/tex]

t = 19035 years

Carbon-14 will take 19,035 years to decay to 10 per cent.
