Mathematics
1 answer:
Debora [2.8K]3 years ago
8 0

Answer:

x^{2} -7x +12

Step-by-step explanation:

Using the Foil method

you multiply x times x and get x^{2}

Then you multiply -4 times X and get -4x

Then you multiply -3 times X and get -3x

then you add -4 and -3 together and get -7x

Lastly you multiply -4 and -3 and get 12

And there you have it

x^{2} -7x +12

When purchasing bulk orders of​ batteries, a toy manufacturer uses this acceptance sampling​ plan: Randomly select and test 49 b
Brilliant_brown [7]

Answer:

Step-by-step explanation:

Given that A shipment contains 6000 ​batteries, and 1​% of them do not meet specifications.

Sample size =49

If x is the number of batteries not meeting specifications then

x is binomial with n =49 and p = 0.01

Because i) each toy is independent of the other

ii) There are only two outcomes

Probability whole shipment is accepted = Prob (X≤3)

=0.9885

Hence almost all shipments would be accepted.

What is an equation of the axis of symmetry for the parabola whose equation is y=2x^2 + 8x-1
docker41 [41]

Answer:

x = - 2

Step-by-step explanation:

The equation of the axis of symmetry is a vertical line with equation

x = c

where c is the value of the x- coordinate of the vertex

The x- coordinate of the vertex is

x = - \frac{b}{2a}

Given

y = 2x² + 8x - 1

with a = 2 and b = 8 , then

x = - \frac{8}{4} = - 2

x = - 2 is the equation of the axis of symmetry
