Plzzz help its due by 12

Answer:

10:51

Step-by-step explanation:

Given that :

Distance from A to B = 130km

Departure time = 8 : 15

Average speed = 50 km/hr

Recall :

Speed = distance / time

Time = distance / speed

Time = (130 km) ÷ (50km/hr)

Time = 130 / 50

Time = 2.6 hours = 2 hours + (0.6 * 60) = 2 hours 36 minutes

Arrival time = (8:15) + (2 hours 36 minutes) = 10:51

it depends what the number is

Answer:

50

Step-by-step explanation:

20 divided by the percent value as a decimal 0.4 is 50

Answer:

(50*20) + (50*7)+(2*20)+(2*7)

Step-by-step explanation:

52 is 50 + 2

27 is 20 + 7

(50*20) + (50*7)+(2*20)+(2*7)

Answer:

x = 128

x - 23 = 105°

Step-by-step explanation:

x - 23° = 105° because these angles are corresponding

x = 105 + 23

x = 128

The value of the angle marked x - 23 = 105

Answer:

y=3x-8

Step-by-step explanation:

y=mx+b

m is the slope

b is the y-intercept

Answer:

10 units

Step-by-step explanation:

Formula to find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Distance between two points (0, -7) and (-6, 1) will be,

d = [tex]\sqrt{(0+6)^2+(-7-1)^2}[/tex]

  = [tex]\sqrt{36+64}[/tex]

  = [tex]\sqrt{100}[/tex]

  = 10

Therefore, distance between the given points is 10 units.

A study done by researchers at a university concluded that ​70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and​ 95% confidence interval for the​ study?

Answer:

Step-by-step explanation:

Given that:

The sample proportion [tex]\hat p = 0.70[/tex]

The sample size n = 1800

At 95% confidence interval level:

The level of significance = 1 - 0.95 = 0.05

Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]

Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]

the Margin of Error E = 0.021

At 95% C.I for the population proportion will be:

[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]

= 0.70 ± 0.021

= (0.70 - 0.021, 0.70 + 0.021)

= 0.679, 0.721)

Answer:

C

Step-by-step explanation:

14 + x ≤ 26

~Subtract 14 to both sides

x ≤ 12

Answer:

24.554

Step-by-step explanation:

Substitute the variables for the given values

2(9.84)(1.3) - (1.3) + (0.27)

25.584 - 1.3 + 0.27

24.284 + 0.27

ok so they had lot of money and then they went down

Step-by-step explanation:

so i think what happen was that they started off at day 1 with 500 dollars around and then they went down to 285 and then 210 around there, so that can mean they must of wasted money on something or something else on the account

Answer:

C

Step-by-step explanation:

your y values which produce the range differ between 2 and 10 which means that will be your range. All of the values are real.

81

Step-by-step explanation:

5 times 6 is 30 times 3 is 90 - 9 is 81

Answer: either 24 or -24

Answer:

A = 60

B = 60

C = 120

D = 60

Step-by-step explanation:

Answer:

A=85

B=58

Step-by-step explanation:

NO. OF 2 point basket⇒ A

NO. OF 3 point basket⇒B

A+B=89⇒ EQN 1

A=27+B

A-B=27⇒EQN 2

EQN 1 - EQN 2

2B=116

B=58

THEREFORE

 A=27+58

A=85

Step-by-step explanation:

Answer:

TRUE

Step-by-step explanation:

In a function, every domain value (x-value) must have exactly one corresponding range value (y-value). This means that in a function, an x-value or input value cannot have two different y-value or output value. Or else, it ceases to be a function.

So, when you substitute a certain value of x into the equation of a function, you can only have one exact value of y for that value of x.

Answer: x+12=16

Step-by-step explanation: hope this helps

Answer: 12

Step-by-step explanation:

Since value of y varies directly with x, we introduce a constant, k which will give:

y = kx

If x = 4, then y = 20 we then calculate the value of k.

y = kx

20 = 4k

k = 20/4

k = 5

We then find the value of x when y = 60. This will be:

y = kx

60 = 5x

x = 60/5

x = 12

The value of x is 12 when y is 60

Answer:

  363

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by ...

  an = a1 +d(n -1)

Here, the first term (a1) is -92, and the common difference is (-85 -(-92)) = 7. The 66th term is ...

  a66 = -92 +7(66 -1) = -92 +455

  a66 = 363
