See thoe lines are same measrue
and all angles in triangle add to 180
so

x+87+33=180
x+120=180
minus 120 both sides
x=60 degrees

3 pounds of grapes cost $5.07. Rounding to the nearest tenth, how many pounds can you purchase for $13.00?
Natali5045456 [20]
So the tenth place is the x in this number 2.x

so rounding to the tenth 5.07
7>5 so round up to 10
5.10

so 13.00

5.10=3 pounds
try and divide by 3
1.7=1 pound

divide 13 by 1.7
13/1.7=7.6 pounds

Answer:

C. Events E and A are independent

Step-by-step explanation:

we will verify each options

(a)

We can use independent events formula

P(B∩C)=P(B)*P(C)

we are given

P(B)=0.4

P(C)=0.25

P(B∩C)=0.05

now, we can plug these values into formula

and we get

0.05=0.4*0.25

0.05=0.1

we can see that left side is not equal to right side

so, this is FALSE

(b)

We can use independent events formula

P(D∩A)=P(D)*P(A)

we are given

P(D)=0.25

P(A)=0.6

P(D∩A)=0.1

now, we can plug these values into formula

and we get

0.1=0.25*0.6

0.1=0.15

we can see that left side is not equal to right side

so, this is FALSE

(c)

We can use independent events formula

P(E∩A)=P(E)*P(A)

we are given

P(E)=0.5

P(A)=0.6

P(E∩A)=0.3

now, we can plug these values into formula

and we get

0.3=0.5*0.6

0.3=0.3

we can see that both sides are equal

so, this is TRUE

(d)

We can use independent events formula

P(D∩B)=P(D)*P(B)

we are given

P(D)=0.25

P(B)=0.4

P(D∩A)=0.15

now, we can plug these values into formula

and we get

0.15=0.25*0.4

0.15=0.1

we can see that left side is not equal to right side

so, this is FALSE

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!! I CANNOT RETAKE THIS!!
gavmur [86]

\text{Use}\\\\a^2-b^2=(a-b)(a+b)\\\\i=\sqrt{-1}\to i^2=-1\\---------------------\\\\x^2+25=x^2+5^2=x^2-(-1)(5^2)=x^2-(i^2)(5^2)=x^2-(5i)^2\\\\\boxed{x^2+25=(x-5i)(x+5i)}

Please please help. Marking Brilliant for the correct answer
NISA [10]

Answer:

x = 19

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x-7+4) * 4 = 8^2

(x-3)*4 = 64

Divide each side by 4

x-3 =16

Add 3 to each side

x-3+3 = 16+3

x = 19

Annalise invested $3,300 in an account paying an interest rate of 2.8% compounded monthly. Assuming
Artist 52 [7]

Answer:

  $4,881.56

Step-by-step explanation:

The future value formula is ...

  FV = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

You have P=3300, n=12, r=0.028, t=14, so the future value is ...

  FV = $3300(1 +0.028/12)^(12·14) = $4881.56

There would be $4881.56 in the account after 14 years.
