Answer:

y = -x -6

Step-by-step explanation:

If we have a slope and a y intercept, we can use slope intercept form

y = mx +b , where m is the slope and b is the y intercept

y = -1x -6

y = -x -6

Answer:

The small tire would make about 127 rotations.

The large tire would make about 38 rotations.

b. Would you rather ride a bicycle made with two large wheels or two small wheels? Explain.

Two large wheels. Because the larger wheel makes a smoother ride and you spend less energy in order to move, compared to smaller wheels. Also, the larger the diameter, the further it can travel over one revolution.

A bicycle with would allow you to travel farther with each rotation of the pedal.

The larger one. Because in one rotation the larger wheel moves 188.49 inches and the smaller one 56.55 inches.

$C= 188.49\text{inches}$

$C= 56.55\text{inches}$

Step-by-step explanation:

- Big wheel 60 inches

- Small wheel 18 inches.

a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.

Considering: $C=\pi d$

Large tire:

$C=60\pi$

$C= 188.49\text{inches}$

$C=\frac{188.49}{12} = 15.7 \text{feet}$

$\frac{600 }{15.7} = 38 \text{rotations}$

Small tire:

$C=18\pi$

$C= 56.55\text{inches}$

$C=\frac{56.55}{12} = 4.71 \text{feet}$

$\frac{600 }{4.71} = 127 \text{rotations}$

Could someone pls help me out ???

Answer:

Option C.

Step-by-step explanation:

$\sf\:x^{2}-3x+7=0$

Use the biquadratic formula.

$\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}$

$\sf\:x=\frac{3(+/-)\sqrt{19}}{2}$

Positive sign:

$\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}$

Negative sign:

$\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}$

Hope it helps ⚜

It is known that 10% of the calculators shipped from a particular factory are defective. what is the probability that at least o

seraphim [82]

P = 10% = 0.1
q = 1 - 0.1 = 0.9
P(at least one defective calculator) = P(1) + P(2) + P(3) + P(4) = 1 - P(0)

The brobability of a binomial distribution is given by
$P(x)=^nC_xp^xq^{n-x}$
where: n = 4
$P(0)=^4C_0(0.1)^0(0.9)^4=1\times1\times0.6561=0.6561$
Therefore,
P(at least one defective calculator) = 1 - 0.6561 = 0.3439
