Answer:
Please check the explanation.
Step-by-step explanation:
Given
P(Z > 1.96)
To determine
What probability expression is equivalent to P(Z > 1.96)
Suppose Z is a standard normal variable.
Therefore,
P(Z > 1.96) = 1 - P(Z ≤ 1.96)
solving
= 1 - Ф(1.96)
= 1 - 0.9750
= 0.0250
The probability of the expression being equivalent to P(z > 1.96) is calculated as 0.0250.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The given information is P(z > 1.96)
Let z is a standard normal variable. Then we have
P(z > 1.96) = 1 – P(z ≤ 1.96)
P(z > 1.96) = 1 – 0.9750
P(z > 1.96) = 0.0250

x-4y=-4
5x – 4y= 12
Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4

y is directly proportional to x.
when y=30, x=6
work out an equation connecting y and x
Answer:
y = 5x
Step-by-step explanation:
Use the direct variation equation y = kx
Plug in 30 as y and 6 as x, then solve for k
y = kx
30 = k(6)
5 = k
Plug in 5 as k into y = kx
y = 5x
So, the equation relating x and y is y = 5x
Answer:
y=5x
Step-by-step explanation:
30 divide by 6 = 5 so y = 5x

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
Answer:
Númer total de ladrillos= 256
Step-by-step explanation:
Dada la siguiente información:
Total de pisos= 16
Total de ladrillos por piso= 16
Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:
Número total de ladrillos= total de ladrillos^2
Número total de ladrillos= 16^2
Númer total de ladrillos= 256
En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet
Answer:
a. 33 sqft
Step-by-step explanation:
The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles
Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)
The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24
The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9
Total area is sum of these two or 24 + 9 = 33
