Solve the following system of equations using substitution, elimination, or elimination by multiplication.

Setler [38]

Answer: (-4, 8)

Explanation:
2x - 7(2x + 16) = -64
2x - 14x - 112 = -64
-12x = 48
x = -4
y = 2(-4) + 16
y = -8 + 16
y = 8

Manuel incorrectly claimed that the surface area of the cylinder

Andre45 [30]

Answer:

25.9%

Step-by-step explanation:

Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem

Let us assume the dimension of the cylinder be

radius= 3in

height= 5 in

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr^2

Let us plug in the values to to find TSA

T. S. A. =2×3.14×3×5+2×3.14×3^2

Solving we get

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

we know that error % is calculated as

%error= [actual value-expected value/expected value]×100

%error= [190 -150.816/150.816]×100

%error= [39.184/150.816]×100

%error= 0.259×100

%error= 25.9%

Answer:

q/2, p, q

Step-by-step explanation:

You know the area of a triangle is half the product of base and height. The two triangles of interest here have base length p and height q/2. You're being asked to fill in the missing base or height dimension.

$=\dfrac{1}{2}\times p \times\boxed{\dfrac{q}{2}}+\dfrac{1}{2}\times\boxed{p}\times\dfrac{q}{2}\\\\=\dfrac{1}{2}\times p\times\boxed{q}$

A fair coin is tossed 20 times. The probability of getting the three or more heads in a row is 0.7870 and the probability of get

adelina 88 [10]

Answer:

The value is $P( H \ n \ T ) = 0.6049$

Step-by-step explanation:

From the question we are told that

The number of times is n = 20

The probability of getting three or more heads in a row is $P(H) = 0.7870$

The probability of getting three or more heads in a row or three or more tails in a row is $P(H \ u \ T ) = 0.9791$

Generally given that it is a fair coin , then $P(H) = P(T) = 0.7870$

Here P(T) is probability of getting three or more tails in a row

Generally the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as

$P( H \ n \ T ) = P(H) + P(T) - P( H \ u \ T )$

=> $P( H \ n \ T ) = 0.7870 + 0.7870 - 0.9791$

=> $P( H \ n \ T ) = 0.6049$
