Answer:

the second graph (c)

Step-by-step explanation:

The curve is passing through (0, 2) and (0, -3). Then the correct option is B.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The zeroes of the polynomial function are 2 and -3.

The number of zeroes is 2. Then the degree of the polynomial will be 2. So, the function is a quadratic function.

The zeroes of the function represent the x-intercepts. Then the curve is passing through (0, 2) and (0, -3).

Thus, the correct option is B.

Answer:

The circumference of the blue circle is about  

62.8 cm.

The circumference of the orange circle is about  

31.4 cm.

Step-by-step explanation:

First the blue circle, it shows that there are 5 cm on the outside of the orange circle so the would be 5+5=10, then you add the orange circle to the 10 cm, that would give you 20 cm. Then you multiply 20 cm by pi (3.14) which will give you your answer 62.8. Do the same thing for the orange circle, 5+5=10 so 10 multiplied by pi (3.14) is 31.4

Answer:

50% of 108: 54

25% of 108: 27

75% of 108:  81

Step-by-step explanation:

Hope this helps have a nice day

Answer:

50% : 54

25% : 27

75% : 81

Step-by-step explanation:

If you multiply by the decimal version of the precentages, you will get the remaining amount of how much it is. so to find 50% of 108, you do 108 * 0.50 and it will give you the 50% of 108.

Answer:

Step-by-step explanation:

I think that's the answer.

The value of P(X ≥ 93) when X pertains a normal distribution with mean of 79 and standard deviation of 7 is 0.0228

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex])

then it can be converted to standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

[tex]P(Z \leq z) = P(Z < z) )[/tex]

Also, know that if we look for Z = z in z tables, the p value we get is

[tex]P(Z \leq z) = \rm p \: value[/tex]

For this case, we're specified that:

X pertains a normal distribution with mean of 79 and standard deviation of 7, symbolically, we have:

[tex]X \sim N(\mu = 79, \sigma = 7)[/tex]
The needed probability is P(X ≥ 93)

Converting X to standard normal variate makes us evaluate this probabiilty as:

[tex]Z = \dfrac{X -\mu}{\sigma} \sim N(0,1)\\\\P(X \geq 93) = 1 - P(X < 93)\\\\P(X \geq 93) = 1 - P\left (Z < \dfrac{93-79}{7}\right)\\\\P(X \geq 93) = 1 - P(Z < 2)[/tex]

The p-value for Z = 2 (from the z-tables) is found to be 0.9772

Thus, we get:

[tex]P(X \geq 93) =1 - P(Z < 2) = 1 - P(Z \leq 2) = 1 - 0.9772\\P(X \geq 93) = 0.0228[/tex]

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Answer:

The speed of the car is 50 mph.

The speed of the plane is 150 mph.

Driving time = 185/50 = 3.7 hours

Flying time = 645/150 = 4.3 hours

Step-by-step explanation:

R be the speed of the car.

t is the driving time.

185 = R* t

645 = (3R)*(8-t) <---  the plane is 3 times as fast; the total time is 8 hours, so 8-t hours is spent flying

645 = 24R - 3rt <--- distributive

645 = 24R - 3(185)  <--- substitutes rt = 185

645 = 24R - 555

1200 = 24R

R = 50

Answer:

Time taken for cover 1 miles = 0.16 hour (Approx.)

Step-by-step explanation:

Given:

Total distance cover by Duncan = 26.2 miles

Time taken by Duncan = 4 hours 10 minutes

Find:

Time taken for cover 1 miles

Computation:

Time taken by Duncan = 4 hours 10 minutes

Time taken by Duncan = 4 + 0.167 hour

Time taken by Duncan = 4.167 hour

Speed = Distance / Time

Speed = 26.2 / 4.167

Speed = 6.28 miles/hour (Approx.)

So,

Time taken for cover 1 miles = 1/6.28

Time taken for cover 1 miles = 0.16 hour (Approx.)

x=24

Step-by-step explanation:

0.22(x+6)=0.2x+1.8

simplify the given equation

0.22x+1.32=0.2x+1.8

shift same kind of variables on one side

0.22x-0.2x=1.8-1.32

0.02x=0.48

For x

x=0.48/0.02

x=24

Check:

For checking subsitute the calculated value x if both sides of x are equal  then its true...

0.22(24+6)=0.2(24)+1.8

5.28+1.32=4.8+1.8
