Answer:

0.76 rounded don't mind my explanation

Step-by-step explanation:

in Geometry if you want a farewell you need to know the parallel lines they never touch they're always the same distance apart it's as if they don't like each other much and there's only one thing that comes between the line that passes right through each of them called the transversal line it has several angle properties just like these: vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180* vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180*

The length of time to complete a door assembly on an automobile factory assembly line is normally distributed with a mean of 6.7
hram777 [196]
We need to work out the z-value of each question to work out the probability

Question a)

We have
X = 5 minutes
The mean, μ = 6.7 minutes
Standard deviation, σ = 2.2 minutes
z-score = (X - μ) / σ = (5 - 6.7) / 2.2 = -0.77

We want to find the probability of z < -0.77 so we read the z-table for the value of z on the left of -0.77 we have the probability P(z< -0.77) = 0.2206

The table is attached in picture 1 below

The probability of assembly time less than 5 minutes is 0.2206 = 22.06%

Question b)

z-score = (10-5) / 2.2 = 2.27

Reading the z-table for P(z<2.27) = 0.9884
The table reading is shown in the second picture below

The probability the assembly time will be less than 10 minutes is 0.9884

We can use this information to find the probability of the assembly time will be more than 10 minutes  = 1 - 0.9884 = 0.0116 = 1.16%

Question c)

The value of z between 5 minutes and 10 minutes is

P(-0.77<z<2.27) = P(z<2.27) - P(z< -0.77)
P(-0.77<z<2.27) = 0.9884 - 0.2206 = 0.7678 = 76.78%

Write the equation of the line that passes through the points (4,-6) and (-2,3)
yarga [219]

Here is your answer and an explanation

Answer: y = -2/3x

Explanation:

This can be determined by calculating the gradient of the straight line, using:

m=ΔyΔx

=−6−34−(−2)

=−96

=−32

Then we use the slope-point form of the straight line:

y−y1=m(x−x1)

to give:

y−3=−32(x−(−2))

∴y−3=−32(x+2)

∴y−3=−32x−3

∴y=−32x

1) Relacione o nome dos polígonos de acordo com o total de lados. a) Triângulo ( ) 8 lados. b) Quadrilatero ( ) 6 lados. c) Pent
GuDViN [60]

Answer:

1

O nome de um polígono é um nome que se deve ao número de lados que o polígono possui.

a) Triângulo = 3 lados.

b) Quadrilátero = 4 lados.

c) Pentágono = 5 lados.

d) Hexágono = 6 lados.

e) Heptágono = 7 lados.

f) Octógono = 8 lados.

2) O ângulo reto, também conhecido como ângulo de um quarto de volta, mede: a) 90 °

3) O ângulo que mede menos 90 ° e mais que 0 ° é denominado: a) agudo

4) 2240

5) 5040 sinalizadores

6) Calcule: a) 861 x 27 = 23247

b) 798 x 45 = 35910

Step-by-step explanation:

1) Liste o nome dos polígonos de acordo com o número total de lados.

a) Triângulo = 3 lados.

b) Quadrilátero = 4 lados.

c) Pentágono = 5 lados.

d) Hexágono = 6 lados.

e) Heptágono = 7 lados.

f) Octógono = 8 lados.

2) O ângulo reto, também conhecido como ângulo de um quarto de volta, mede: a) 90 ° b) 180 ° c) 270 ° d) 360 °

= a) 90°

Um triângulo ângulo reto pode ser definido como um triângulo onde um de seus 3 ângulos é equivalente a 90 graus (90°).

3) O ângulo que mede menos 90 ° e mais que 0 ° é denominado: a ) agudo b) raso c) reto d) obtuso.

Um ângulo maior que 0 ° e menor que 90 ° pode ser definido como um ângulo agudo.

= a) agudo

4) Um teatro com 64 filas de assentos e cada fila tem 35 assentos. Qual é a capacidade deste teatro?

No teatro, cada fila tem 35 lugares.

Temos 64 linhas

O número total de licenças que temos é calculado como:

1 fila = 35 assentos

64 linhas =

Multiplicação cruzada

64 filas × 35 assentos

= 2.240 assentos.

Portanto, a capacidade do teatro é de 2240.

5) André e Federico confeccionaram 28 embalagens contendo 180 bandeiras cada embalagem. Quantas bandeiras os meninos fizeram?

O número de bandeiras que os meninos fizeram é calculado como:

28 pacotes × 180 bandeiras

= 5040 sinalizadores

6) Calcule: a) 861 x 27 = 23247

b) 798 x 45 = 35910
