Step-by-step explanation:

Answer:

P(x≤14) = 0.556

Step-by-step explanation:

Given:

Probability of throwing a strike (p) = 0.487

Total number of throw (n) = 29

Find:

Probability that no more than 14 of them are strikes P(x≤14)

Computation:

Mean(np) = (29)(0.487)

Mean(np) = 14.123

Standard deviation = √[mean( 1- p)]

Standard deviation = √[14.123( 1 - 0.487)]

Standard deviation = 2.6917  (Approx)

P(X < x) = P[(Z < (x - mean)]/[Standard deviation])

P(x≤14) = P(Z < (14.5 - 14.123) / 2.6917 )

P(x≤14) = 0.556

Answer:

a = (u-2b)/6

Step-by-step explanation:

First get a by itself by subtracting 2b from both sides:

u-2b = 6a

Then isolate the variable by dividing both sides by six:

(u-2b)/6 =a

This question is incomplete, the complete question is;

Find the vector form of the general solution to the given linear system Ax = b; Then use that result to find the vector form of the general solution to Ax = 0.

x1   + x2 + 2x3 = 5

x1            +  x3  = -2

2x1 + x2 +  3x3 = 3

Answer:

the vector form of the general solution to the given linear system Ax = b

x1          -2                -1

x2   =     7         +s    -1

x3          0                 1

find the vector form of the general solution to Ax = 0.

x1                -1

x2   =    s    -1

x3                1

Step-by-step explanation:

Given that;

x1   + x2 + 2x3 = 5

x1            +  x3  = -2

2x1 + x2 +  3x3 = 3

Augmented matrix is expressed as;

1   1    2          5

1   0   3         -2

2  1    3          3

R2 ← R2 - R1        

1   1    2         5

0  -1   -1        -7

2  1    3         3

R3 ← R3 - 2R1

1   1    2         5

0  -1   -1        -7

0  -1   -1        -7

R3 ← R3 - R2

1   1    2         5

0  -1   -1        -7

0  0   0        0

R1 ← R1 + R2

1   0   1         -2

0  -1   -1        -7

0  0   0        0

R2 ← - R2

1   0   1         -2

0  1    1         7

0  0   0        0

SO from the above reduced matrix, we get

x1 = -2 - x3

x2 = 7 - x3

x3 = x3

now we introduce parameter "s" for free variable x3

x1 = -2 - s

x2 = 7 - s

x3 = s

x1          -2                -1

x2   =     7         +s    -1

x3          0                 1

General solution of Ax = 0 will be

x1                -1

x2   =    s    -1

x3                1

The solution of the expression is (55z + 6 ) / 20.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that the expression is 3/4(z+2/5)+2z. The expression will be solved as below,

E = 3/4(z+2/5)+2z

E = 3/4( z + 2 / 5 ) + 2z

E = 3/4 ( 5z + 2) / 5 + 2z

E = ( 15z + 6 + 40z ) /20

E = (55z + 6 ) / 20

Therefore, the solution of the expression is (55z + 6 ) / 20.

Answer:

The answer is below

Step-by-step explanation:

Let us assume the angle is -π/4.

Coterminal angles are angles that have the same initial side and terminal side. They are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Positive coterminal angles are gotten by adding 360° if the angle is in degrees or 2π for angles in radian while negative coterminal angles are gotten by subtracting 360° if the angle is in degrees or 2π for angles in radian.

Positive coterminal angle = -π/4 + 2π = 7π/4, 7π/4 + 2π = 15π/4

Positive coterminal angle = 7π/4, 15π/4

Negative coterminal angle = -π/4 - 2π = -9π/4, -9π/4 - 2π = -17π/4

Negative coterminal angle = -9π/4, -17π/4

96.25 for 25 gallons

3.85 times 25 and that's your answer

Answer:

Step-by-step explanation:

Step one:

Given that the capacity of the gas tank is 24 gallons.

we know that 1 mile will consume 0.06 gallons

therefore x miles will consume 0.06x gallons.

the consumption for any distance is given as

0.06x gallons.

Step two:

if x=240 miles

then the gallons consume will be

0.06(240)=14.4 gallons

Step three:

the remaining gallons of gas in the tank will be

24-14.4=9.6 gallons

The reamining gallons will be 9.6 gallons

Answer:

$15,475

Step-by-step explanation:

Mr. and Mrs. Jones make a combined $92,400 in taxable income. Looking at the table, their income is over $67,900 but not over $137,050.

So, the tax is $9,350. But, it also includes 25% of the amount over $67,900.

So,

$92,400 - $67,900 = $24,500

0.25 × $24,500 = $6,125

$9,350 + $6,125 = $15,475
