Answer:

Step-by-step explanation:

Alright, lets get started.

Once the triangle has all angles less than 90 degree, is called Acute triangle.

Once the triangle has one angle more than 90 degree, is called Obtuse triangle.

Once the triangle has one angle equal to 90 degree, is called Right triangle.

So, the given triangle has its angle 55, 55, 70.

Each angle is acute angle, so the triangle is Acute triangle. : Answer

Hope it will help :)

The speed of motor vehicles on a certain stretch of road are normally distributed with a mean of 64.2 mph and a standard deviati

Arte-miy333 [17]

Answer:

a ) P(x> 65) = 0.4641

b) P(x< 60) =0.6915

c) P(65< x<80) = 0.4334

Step-by-step explanation:

Given data:

$\mu = 64.2$

$\sigma = 8.44$

$z =\frac{x-\mu}{\sigma}$

a) $P(x> 65) = P(z> \frac{65 - 64.2}{8.44})$

= P(z>0.09)

=0.4641

b) $P(x< 60) = P(z< \frac{60 - 64.2}{8.44})$

= P(z < 0.50)

=0.6915

c) P(65 < x <80)

$= P(x$

$= P(z< \frac{80 - 64.2}{8.44}) - P(z< \frac{65 - 64.2}{8.44})$

$= P(z < 1.87) - P(z < 0.09)$

= 0.9693 - 0.5359

= 0.4334

Write the simplest polynomial function for each set of zeros Zeros = -2, 5, -1

deff fn [24]

Answer:

The polynomial is ;

x^3 -2x^2 -13x - 10

Step-by-step explanation:

Given the zeros, we set them to equal zero so as to get the linear factors

Mathematically, that will be as follows;

x = -2

x + 2

x = 5

x-5

x = -1

x + 1

So we have the polynomial as;

(x + 1)(x + 2)(x-5)

= (x -5)(x^2 + 3x + 2)

= x^3+ 3x^2 + 2x -5x^2 -15x - 10

= x^3 -2x^2 -13x - 10

Please I have the answers I just want to double check them and Solve key: B=42 A=93 N=29 X=36 1. (b-7)(2b-7) 2. (4a-4)(5a-7)

Nady [450]

1. (b-7)(2b-7) = 2 $b^{2}$ -21b +49; b = 42 => 2* $41^{2}$ -21*42 + 49 =
3528 - 882 + 49 = 2695;

A box contains 5 plain pencils and 7 pens. A second box contains 3 color pencils and 3 crayons. One item from each box is chosen

Andru [333]

Multiply the two desired probabilities to find the answer.

5/12 is the probability for the plain pencil since there are 5 pencils out of 12 total items.

1/2 is the probability for the colored pencil since there are 3 colored pencils out of 6 total items. 3/6 simplifies to 1/2.

5/12*1/2= 5/24

Final answer: 5/24
