Answer:

(x-6)

Step-by-step explanation:

given

length= x-5

area= x^2-11x+30

so expand given area,

u will get 2 roots,

among them given x-5 is length, while obtained x-6 is width.

Which sequence of transformations creates a similar but not congruent triangle?

Vsevolod [243]

Answer:

<h3> A. Dilation and reflection</h3>

Step-by-step explanation:

There are the same angles in similar triangles but sides not necessarily.

In congruent triangles there are the same angles and the same sides.

Reflection, rotation or translation changes only position of triangle or mirrors it. Doesn't change the size, so the created triangle is congruent.

The number of chocolate chips in an 18-ounce bag of Chips Ahoy! chocolate chip cookies is approximately normally distributed wit

sineoko [7]

Answer:

a) 0.013

b) 0.7

c) 0.866

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 1262

Standard Deviation, σ = 118

We are given that the distribution of number of chocolate chips is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(fewer than 1000 chocolate chips)

P(x < 1000)

$P( x < 1000) = P( z < \displaystyle\frac{1000 - 1262}{118}) = P(z < -2.220)$

Calculation the value from standard normal z table, we have,

$P(x < 1000) = 0.013 = 1.3\%$

b) P(contains more than 1200 chocolate chips)

$P(x > 1200) = P(z > \displaystyle\frac{1200-1262}{118}) = P(z > -0.5254)\\\\P( z > -0.5254) = 1 - P(z \leq -0.5254)$

Calculating the value from the standard normal table we have,

$1 - 0.300 = 0.7 = 70\%\\P( x > 1200) = 0.7$

c)P(contains between 1000 and 1400 chocolate chips)

$P(1000 \leq x \leq 1400) = P(\displaystyle\frac{1000 - 1262}{118} \leq z \leq \displaystyle\frac{1400-1262}{118}) = P(-2.22 \leq z \leq 1.169)\\\\= P(z \leq 1.169) - P(z < -2.22)\\= 0.879 - 0.013 = 0.866 = 86.6\%$

$P(1000 \leq x \leq 1400) = 86.6\%$

Write an absoulute value equation that has the solutions x= -6 and x= 10

irina [24]

Answer:

The quadratic equation is X^2 -4X-60=0

Step-by-step explanation:

You solve by using the relation

X^2-(Sum)X + Product

which is (-6+10)X +(-6×10)

=X^2 -4X -60

X^2 +6x -10x -60 =0

(X^2+6x)-(10x-60)

=X(X+6)-10(x+6)

=(X-10)(X+6) =0

x-10=0. and x+6=0

x=10. x=-6

Therefore the quadratic equation is given by x^2 -4x -60
