test of 250 questions

40% of the fist 125 are ok, this means that 125(0.4) = 50 questions of the first 125 are ok

If jassi needs 60% of the 250 ok, that is 250(0.6) = 150

If of the first half she already has 50 questions ok, and needs 150, she needs to have 100 questions our of the second 125

If she needs 100 out of 125, this percent is 100/125 = 0.8, this means 80%

Answer:

Jassi needs 80% of the second 125 questions to be ok

Step-by-step explanation:

8x+4y=20 turns into:

y=2x+5

3y-12x=0 turns into:

y=4x

9x-2y=6 turns into:

y=-3+9/2x

Answer:

Step-by-step explanation:

To solve the equation of 7/3x+1/3x=1+5/3x, isolate the term of x from one side of the equation.

First, you subtract by 5/3x from both sides.

[tex]\rightarrow \sf{\dfrac{7}{3}x+\dfrac{1}{3}x-\dfrac{5}{3}x=1+\dfrac{5}{3}x-\dfrac{5}{3}x}[/tex]

Solve.

[tex]\rightarrow \boxed{\sf{x=1}}[/tex]

Therefore, the solution is x=1, which is our answer.

I hope this helps, let me know if you have any questions.

David takes a car to get to the airport in time for his trip. 210 miles distance is the airport from his house in miles.

Given that,

David takes a car to get to the airport in time for his trip. He travels 35 miles in the first hour but understands that if he keeps going at this rate, he will be one hour late. For the final 15 miles to the airport, he speeds up by 15 mph and gets there 30 minutes early.

We have to find how far is the airport from his house in miles.

Distance traveled after 1 hour

Let us take the distance traveled after first 1 hour as y

Distance/speed = time

After 1 hour his speed = (35 + 15) = 50 mph

Total time count of 1 hour and 30 mins is 1.5 hr

y/50 + 1.5 = y/35

Multiply through by350

7y + 525 = 10y

3y = 525

y = 525/3

y = 175 miles

In the first 1 hour, at 35 mph, distance covered = 35 miles

Distance from his home to airport = 175 miles + 35 miles = 210 miles

Therefore, the distance between David's home and the airport is 210 miles.

Since the vertex is at (-1, -3), the only appropriate option is to translate the function one unit to the left, and again translating 3 units down, with the following form:

g(x) = |x+1| - 3

Therefore, the solution is the last option.

Center of circle = (-3, 6)

Diameter = 6

General equation of circle: x² + y² = r²

our answer will be in the form:

(x+a)² + (y+b)² = r²

Substitute center values and radius:

a = 3 (x was -3 but we don't trust it! It should be positive instead of negative)

b = -6 (same rules apply. Don't trust the value in the center. Its the opposite.)

r = 6/2 which is 3

answer: (x+3)² + (y-6)² = 3²

The addition symbol (+) can be used in between the two parentheses to show that you will be using the distributive property.

Distributive property:

The distributive property states that multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.

It can be written as,

a x (b + c) = (a x b) + (a x c)

Where a, b and c are the values of the variables.

Given,

Here we have the expression:

8 x 57 = (8 x 50) _____(8x7)

Here we need to find the symbol that can be used in between the two parentheses to show that it will be using the distributive property.

Based on the definition of the distributive property we have know that the symbol (+) can be used to make this one as distributive property used equation.

Answer:

Step 3

Step-by-step explanation:

The mistake was made in Step 3.

Answer:

x = ?

Step-by-step explanation:

Since there are two congruent angles, their respective sides are also congruent (an angle's respective side is the side opposing it, the side that it does not touch). Meaning, the 3x-7 side is congruent to the 2x side.

So just set them equal to each other to find x.

3x - 7 = 2x

x = ? (You can do this. Solve for x algebraically.)

The 4x-10 doesn't really matter here since you just need to find x.

Answer:

Domain: [0,∞)

Range: (-∞,4]

Step-by-step explanation:

The domain is the numbers along the x-axis, and the range is the numbers along the y-axis. This graph includes a domain from zero to infinity and a range from negative infinity to four. The parentheses () mean that these numbers aren't included, and since infinity isn't an actual number, it gets a parenthesis. The brackets [ ] are used to include a number exactly. Since four and zero are real numbers and are included in this graph they get brackets. We also know that four and zero are included because the dot at point (0,4) is solid and not hollow, which means those numbers are to be included in the domain and the range. Also something to note: you always write the domain and range going from the smallest number to the largest number, this is why the range is written as (-∞, 4] and not [4, -∞).

Recall the definition of the cosecant function in terms of the sine function:

Draw the angle -210º in the unit circle to find a reference triangle for that angle:

Notice that a 30-60-90 triangle is formed:

Since the side opposite to the 30º angle has a length of 1/2, then:

On the other hand, notice that since the angle of -210º lies in the second quadrant, then the value of sin(-210º) is positive:

Use the definition of the cosecant function to find csc(-210º):

Therefore, the value of csc(-210º) is equal to 2.

Answer:

b = 18

The mortar is 17 times ( 3 / 8 ) tall.

The brick height is equal to 18 times ( 2 + ( 1 / 4 ) ).

I don't know the options, so you have to use those values.

Step-by-step explanation:

The question uses imperial units which are generally bad.

12 inches = 1 feet;

The height of the wall should be written in inches for convenience.

4 feet = 4 * 12 inches;

4 feet = 48 inches;

The wall is short 1 + ( 1 / 8 ) inches short of 4 feet.

48 inches - ( 1 + ( 1 / 8 ) inches ) = 46 + ( 7 / 8 ) inches;

Now that the wall is done let's do the bricks. The height of the bricks is 2 + ( 1 / 4 ) inches and the mortar is ( 3 / 8 ) inches tall. The amount of mortar is the number of bricks - 1 because nobody puts extra mortar on the top of the wall.

let b;

46 + ( 7 / 8 ) = b( 2 + ( 1 / 4 ) ) + ( b - 1 )( 3 / 8 );

375 / 8 = b( 9 / 4 ) + ( 3 / 8 )b - ( 3 / 8 );

375 / 8 = ( ( 9 / 4 ) + ( 3 / 8 ) )b - ( 3 / 8 );

375 / 8 = ( ( 18 / 8 ) + ( 3 / 8 ) )b - ( 3 / 8 );

375 / 8 = ( 21 / 8 )b - ( 3 / 8 );

Multiply both sides by 8 to get rid of those annoying fractions.

375 = 21b - 3;

Add 3 to both sides.

378 = 21b;

Divide both sides by 21.

18 = b;

The probability that the sample mean would differ from the true mean by more than $2.5 is 0.0062

Mean cost of the five pound shrimp bag = $40

Variance of the five pound shrimp bag = $36

The number of the shrimp bag = 43

The given mean value = $2.5

The z-score = $2.5

The probability of the sample mean differ by $2.5 from the true mean can be calculated by

  P(z > 2.5) = 1 - P(z < 2.5)

From the z table , we can get the value of  z < 2.5 which is 0.9938

    P(z > 2.5) = 1 - 0.9938

   P(z > 2.5) = 0.0062
