Answer:

don't understand

what do u mean

Answer:

a = 2.5

Step-by-step explanation:

It is mentioned that 2 is a zero of the polynomial f(x) = ax² - 3(a - 1)x - 1

So that means :

⇒ f(x) = 0

⇒ x = 2

Substituting and solve for a :

⇒ 0 = a(2)² - 3(a - 1)(2) - 1

⇒ 0 = 4a - 6(a - 1) - 1

⇒ 0 = 4a - 6a + 6 - 1

⇒ 2a = 5

⇒ a = 2.5

Answer:

0.892

Step-by-step explanation:

The probability that it is raining and the flight is delayed is 0.008.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, the probability that it will rain is 0.14 and the probability that the flight will be delayed is 0.06.

Let P(A)=0.14 and P(B)=0.06

Here, P(A and B)=P(A)×P(B)

=  0.14 ×0.06

= 0.0084

= 0.008

Therefore, the probability that it is raining and the flight is delayed is 0.008.

Answer:

(a)  (3, 0) and (-8, 0)

(b)  (-2.5, 0)

(c) x = -2.5

(d) f(-2.5) = -30.25

Step-by-step explanation:

Given quadratic function:

[tex]f(x)=(x-3)(x+8)[/tex]

The x-intercepts are when [tex]f(x)=0[/tex]

[tex]\implies f(x)=0[/tex]

[tex]\implies (x-3)(x+8)=0[/tex]

[tex]\implies (x-3)=0 \implies x=3[/tex]

[tex]\implies (x+8)=0 \implies x=-8[/tex]

Therefore, the x-intercepts are (3, 0) and (-8, 0)

Midpoint between two points:

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad[/tex]

[tex]\textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

[tex]\implies \textsf{Midpoint of the x-intercepts}=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-2.5},0\right)[/tex]

The extreme point of a quadratic function in the form [tex]f(x)=ax^2+bx+c[/tex] is:

[tex]x=-\dfrac{b}{2a}[/tex]

Therefore, expand the function so that it is in standard form:

[tex]\implies f(x)=x^2+5x-24[/tex]

[tex]\implies a=1, b=5[/tex]

Therefore, the extreme value is:

[tex]\implies x=-\dfrac{5}{2}=-2.5[/tex]

Alternative method

A quadratic function has an extreme value at its vertex.

The x-value of the vertex is the midpoint of the x-intercepts.

Therefore, the extreme value is x = -2.5

[tex]\begin{aligned}\implies f(-2.5) & =(-2.5-3)(-2.5+8)\\& = (-5.5)(5.5)\\& = -30.25\end{aligned}[/tex]

The different units of measurement (millimeters, centimeters, meters and kilometers) are used to measure from very short distances such as the amount of a medicine in a syringe to long distances between cities.

Measurement units are a series of references that are used to measure different elements and factors. Specifically, the units of measure for distance measure the distance between two points.

However, not all units of measure work for all situations, for example:

Answer:

bule is in the spot of green in the sixth place of box 5

Step-by-step explanation:

Answer:

0.48.

Step-by-step explanation:

There are 2 ways that a tail lands once:-

Tail + head or

head + tail.

Prob(Tail on one throw) = 0.4

Prob(Head on one throw) = 1 - 0.4 = 0.6.

Prob(Tail first then head) = 0.4 * 0.6 = 0.24

Head then tail has the same probability (0.6*0.4).

So the requred probability = 0.24 + 0.24

= 0.48.

[tex]~~~~~~(8x-17)+(3x+2)+63 = 180\\\\\implies 11x +48=180\\\\\implies 11x = 180-48\\\\\implies 11x = 132\\\\\implies x= \dfrac{132}{11}\\\\\implies x= 12[/tex]

Answer:

x = 12.

Step-by-step explanation:

The sum of the 3 angles is 180, so:

8x - 17 + 3x + 2 + 63 = 180

11x -15 + 63 = 180

11x = 180  + 15 - 63

11x = 132

x = 132/11 = 12

The probability of getting the green apple is 7/20 option (B) 7/20 is correct.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

P(red) = 2/5

P(yellow) = 1/4

The sum of the probability of the event is 1.

P(red) + P(yellow) + P(green) = 1

2/5 + 1/4 + P(green) = 1

P(green) = 1 - (2/5 + 1/4)

P(green) = 7/20

Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.
