cube root of 8 is 2

factors of 24= 2*2*2*3

cube root of 24 = 2∛3

Under cube root we have x and x⁵

so multiplying , x*x⁵ we have x⁶

∛x⁶ = x²

so we have ∛8x * ∛24x⁵ equal to 2*2*x²∛3

so answer is 4x² ∛3

option C is the correct answer

Which of the following is a perfect square trinomial?

Snowcat [4.5K]

Answer:

$x^2-5x+6\\(x-3)(x-2)$

$x^2-3x+4\\(x-4)(x+1)$

$x^2+20x+100\\(x+10)(x+10)\\(x+10)^2$

That's the answer

$x^2+14x-49\\x(x+14)-49$

Only $x^2+20x+100$ is a perfect square trinomial

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the gi

Lina20 [59]

Answer:

y=-4x-14

Step-by-step explanation:

Lines that are parallel would have the same slope, so the slope is

m= -4

Use point slope equation to solve for the slope intercept equation.

y-y1=m(x-x1)

m= -4

x= -3

y= -2

y-(-2)=-4(x-(-3))

y+2=-4x-12

y=-4x-14

A survey of 400 non-fatal accidents revealed that 268 involved a distracted driver using some kind of electronic device. Constru

Misha Larkins [42]

A 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%

The 95% confidence interval for the proportion is expressed according to the formula;

$CI=p\pm z\sqrt{\frac{p(1-p)}{n} }$

p is the proportion = 268/400 = 0.67

z is the 95% z-score = 1.96

n is the sample space = 400

Substitute the given parameters into the formula to have:

$CI=0.67\pm 1.96\sqrt{\frac{0.67(1-0.67)}{400} }\\CI=0.67\pm 1.96\sqrt{\frac{0.67(0.33)}{400} }\\CI=0.67\pm 1.96(0.0235)\\CI=0.67 \pm 0.0461\\CI=(0.67-0.0461, 0.67+0.0461)\\CI=(0.624, 0.7161)\\CI = (62.4 \%, 71.61 \%)$

Hence a 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
