Answer:

second option. One lap around the mall is equal to about 2,425 steps

TheThe statement that  is true about the graph of the line representing Debi’s data is: One lap around the mall is equal to 2,425 steps.

Given:

With the 0 lap she has 1,875 steps

With 1 lap she has 4,300 steps

Hence:

One laps around the mall= 4,300 steps-1,875 steps

One laps around the mall=2,425 steps

Therefore the correct option is B.

Answer: b = √6

Step-by-step explanation: Use the Pythagorean Theorem to solve this.

a² + b² = c²

Plug in your values:

2√3² + b² = 2b²

When a square root is squared, the square root is cancelled out so you will be left with this:

2(3) + b² = 2b²

Subtract b² from both sides so you’re left with:

6 = b²

Now, to get rid of the square, just square root both sides:

√6 = √b²

Since the √6 is not a perfect square, leave it in the radical. Then, you get your answer:

b = √6

Answer:

Step 1: Calculate percentage discount

=> $97,899.99 × 25/100

=> 97,899.99/1 × 25/100

{multiply the numerator by the numerator and the denominators by the denominators}

=> 2,447,499.75/100

divide 24,474.9975 by 100

=> 24,474.9975

=> 24,474.9975

{Substract 24,474.9975 from 97,899.99.}

=> 97,899.99 - .24,474.9975

=> 73,424.9925

Step 2: Calculate sales tax rate

Sales tax rate = price × rate/100

=> 73,424.9925 × 3.75/100

=> 275,343.7/100

=> 2,753.437

Add to 73,424.9925

=> 73,424.9925 + 2,753.437

=> 76,178.4295

=> 76,178.4 { Rounded to 1 dp)

Therefore, the total price of the purchases is 76,178.4295

Answer:

14

Step-by-step explanation:

The student is paid K50 each day so after 20 days they should have K1000 but he is paid K700 which means they missed some days of work.

So we divide K700 by K50 which then gives us 14, therefore the student worked 14 days out of 20.

Answer:

-1

Step-by-step explanation:

Gradient is another word for slope, and slope can be defined as rise/run.

From the point (0,0) to (1,-1), it moved one unit down and one unit to the right. The slope for this line can be represented as -1/1, which is equal to -1.

Therefore, the gradient of the graph shown is -1.

Answer:

3) D

5) C

3) 6m+5n-m --> 6(5)+5(3)-(5)

                          30+15-5 --> 45-5 --> 40

5) 4(x+4)+2

   4x + 16 +2

   4x +18

Answer:

3)

Given:

m = 5

n = 3

We plug in these values into our equation (6m + 5n - m);

6m + 5n - m

Now modified, would be:

6(5) + 5(3) - 5

30 + 15 - 5

45 - 5

= 40

5)

If we simplify this expression,

4(x + 4) + 2

We use the distributive property to multiply 4 to both x and 4 which are in the brackets.

Which will now be;

4x + 16 + 2

Now we combine like terms (our constants):

(16 + 2) = 18

So it would be, now:-

4x + 18, C is your answer.

______

Answer:

The correct option is  A

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 0.8 \ pounds[/tex]

    The standard deviation is  [tex]\sigma = 0.25 \ pounds[/tex]

Generally the the probability that a  randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as

       [tex]P(0.55 < X < 1.3) = P(\frac{0.55 - 0.8}{ 0.25} < \frac{X - \mu}{\sigma } < \frac{1.3 - 0.8}{0.25})[/tex]

=>    [tex]P(0.55 <  X  <  1.3)  =  P( -1 <  Z  <  2 )[/tex]

So looking the option of normal curves given in the question we see that it is option A that matches our interval  

The maxima of f(x) occur at its critical points, where f '(x) is zero or undefined. We're given f '(x) is continuous, so we only care about the first case. Looking at the plot, we see that f '(x) = 0 when x = -4, x = 0, and x = 5.

Notice that f '(x) ≥ 0 for all x in the interval [0, 5]. This means f(x) is strictly increasing, and so the absolute maximum of f(x) over [0, 5] occurs at x = 5.

By the fundamental theorem of calculus,

[tex]\displaystyle f(5) = f(0) + \int_0^5 f'(x) \, dx[/tex]

The definite integral corresponds to the area of a trapezoid with height 2 and "bases" of length 5 and 2, so

[tex]\displaystyle \int_0^5 f'(x) \, dx = \frac{5+2}2 \times 2 = 7[/tex]

[tex]\implies \max\{f(x) \mid 0\le x \le5\} = f(5) = f(0) + 7 = \boxed{13}[/tex]

Answer:

x = 8

Step-by-step explanation:

5(x-2)=30

Distribute

5x- 10 = 30

Add 10 to each side

5x-10+10 = 30+10

5x= 40

Divide by 5

5x/5=40/5

x = 8

Answer:

x=

Step-by-step explanation:

using distributive property, you multiply 5 by x and by 2, which gets you 5x and 10

5(x-2)=30

5x-10=30

5x=40

x=8
