hey i need help with question 3 i put 81.5% but i’ve been told it’s been wrong ?

Answer:

241

Step-by-step explanation:

arithmetic sequence formula

A = a + f × (n-1)

n=the nᵗʰ term in the sequence

a=the first term in the sequence

f=the common difference between terms

31+11(20-1)=241

Answer:

2/5 < 7/10

I think this is it

Answer:

2/5 < 7/10

The least common denominator is 10 so if you do 5*2 = 10 and 2*2 = 4 then compare it to 7/10, it would be less than because 4/10 is not greater than 7/10.

Answer:

150%

Step-by-step explanation:

Answer:

Two events are independent if the outcome of the first event does not affect the outcome of the second event.

Step-by-step explanation:

two events are independent if the occurrence or outcome of the  first event does not affect the outcome or occurrence of the second event.

for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events

two outcomes are dependent if the outcome one event is determined by the outcome of the first event.

Answer:

The y-int represents the base price of $200 for airfare from NYC

The slope represents a cost of 30 cents per mile traveled

If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x

If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x

Answer:

[tex] 4,220.16 \: {units}^{3} [/tex]

Step-by-step explanation:

Diameter of cone = 24 units

Radius of cone (r) = 24/2 = 12 units

Height of cone (h) = 28 units

[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} [/tex]

Answer:

Yes

Step-by-step explanation:

Answer:

2392in^2

Step-by-step explanation:

Given data

Dimension

Height 22 inches

Lenght= 20inches

Width= 18inches

The expression for the total surface area is

TSA=2(lw + lh + wh)

Substitute

TSA=2(20*18+20*22+18*22)

TSA=2(360+440+396)

TSA=2*1196

TSA=2392 in^2

Hence the total surface area is 2392in^2

Answer:

Answer:

10+3+3+33+33+15=97

Step-by-step explanation:

Answer:

0.00987

Step-by-step explanation:

Using binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

p = 0.725 ; number of trial, n = 30

Number of winning, x = 16

1 - p = 1 - 0.725 = 0.275

P(x = 16) = 30C16 * 0.725^16 * 0.275^14

P(x = 16) = 119759850 * 0.725^16 * 0.275^14

P(x = 16) = 0.00987

Hence, the probability of winning 16 of their next 30 games is 0.00987

Answer:

y=[tex]\frac{21*97^x}{100^x}[/tex], x= all real numbers

Answer:

1, 2, -3, 51

Step-by-step explanation:

0 ÷ 2 = 0, then + 1 = 1

2 ÷ 2 = 1, then + 1 = 2

-8 ÷ 2 = -4, then + 1 = -3

100 ÷ 2 = 50, then + 1 = 51

Step-by-step explanation:

Use the Pythagorean Theorem ( [tex]a^{2}+b^{2} =c^{2}[/tex] )

The longest side is c = the hypotenuse, and a and b = the other sides of the triangle.

a = 4                              First: [tex]4^{2}+x^{2}=8.5^{2}[/tex]

b = x                         Second: [tex]16+x^{2}=72.25[/tex]  

c = 8.5                          Third: [tex]x^{2}=56.25[/tex]

                                  Fourth: [tex]x=\sqrt{56.25}[/tex]

                                      Fifth: x = 7.5

Answer:

3:2

Step-by-step explanation:

Answer:

3:2 , 18:12 , 27:18

Step-by-step explanation:

There are endless ratios that are equal to 9:6.

Such as 3:2 , 18:12 , and 27:18.

To find equivalent ratios, simply divide or multiply the two numbers in the ratio by the same number.

For example, the ratio is 9:6.

9/3 = 3

And, 6/3 =2

So therefore an equivalent ratio is 3:2.
