A. -2.5
B. 0.0062
C. 0.9938
D. 2.5
Answer:
0.006
Step-by-step explanation:
We are actually looking for the area under the standard normal curve to the left of 50. The proper distribution function on my old TI calculator is normalcdf(:
normalcdf(-1000,50,75, 10),
which returns 0.006 (Answer B)

Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?
Answer:
840 soles
Step-by-step explanation:
Sea la cantidad de dinero que Mateo tenía al principio = x
Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 soles,
Por eso,
3/7 × x = 360 soles
3x / 7 = 360 soles
Multiplicar cruzada
3x = 7 × 360 soles
x = 7 × 360 soles / 3
x = 840 soles
Por tanto, el dinero que tenía Mateo al principio es de 840 soles

Is the ordered pair (-6,3) a solution of the inequality -4x - 8y < 15 ?
A) Yes, the ordered pair is a solution
B) No, the ordered pair is not a solution.
Given:
The inequality is:
[tex]-4x-7y<15[/tex]
To find:
The whether (-6,3) is a solution of given inequality of not.
Solution:
We have,
[tex]-4x-7y<15[/tex]
We need to check the inequality for point (-6,3).
Substitute [tex]x=-6, y=3[/tex] in the given inequality.
[tex]-4(-6)-7(3)<15[/tex]
[tex]24-21<15[/tex]
[tex]3<15[/tex]
This statement is true. It means the point (-6,3) satisfies the given inequality.
Therefore, the correct option is A. Yes, the ordered pair is a solution.

What is the first step you will use to solve this equation:
4x +2 = 7x - 13
1. Subtract 2 from both sides of the equation
4x + 2 = 7x - 13
4x + 2 - 2 = 7x - 13 - 2
2. Simplify
4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15
3. Subtract 7x from both sides of the equation
4x = 7x - 15
4x - 7x = 7x - 15 - 7x
4. Simplify
4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15
5. Divide both sides of the equation by the same term
-3x = -15
-3x/-3 = -15/-3
6. Simplify
-3x/-3 = -15/-3
x = -15/-3
x = 5
7. Solution
x = 5

Answer:
288 square inches
Step-by-step explanation:
since we are not told what to find, we can as well find the volume of the prism
Volume of the prism = BH
B is the base area = 1/2 * 6 * 8
B = 48/2
B = 24 square inches
H is the height of the prism = 12in
Volume of the prism = 24 * 12
Volume of the prism = 288 square inches

Answer:
13y = 52
Step-by-step explanation:
6x - 6x + 4y + 9y = (46 + 6)
6x - 6x + 4y + 9y = 52
0 + 4y + 9y = 52
0 + 13y = 52

A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?
STEP BY STEP PLS
Answer:
23ft approx
Step-by-step explanation:
Given data
Distance from tree= 10ft
Length of ladder= 25ft
We can find the height of the tree by applying the Pythagoras theorem
z^2= x^2+y^2
z= The height of the ladder
x= The distance from the tree
y= The height of the tree
25^2= 10^2+ y^2
625=100+y^2
625-100=y^2
525=y^2
y= √525
y= 22.91
Hence the height of the tree is 23ft approx

The value of the 9 in 901,532 is how many times the value of the 9 in 157,900?
NEED HELP!!!
Answer:
the answer for this question is 1000times.
Step-by-step explanation:
the value for 9 in 157,900 is nine hundred(900).and the value of 9 in 901,532 is nine hundred thousand(900000).
900×1000= 900,000.
The place value of the number 9 in the first number is 1000 times greater than the second number.
What is the standard decimal form of numbers?The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.
Each digit has a face value and a place value.
Given, A number 901,532, So the place value of the number 9 is 900000.
And, In the number 157,900, The place value of 9 is 900.
Therefore, The number of times the value of 9 is greater in 901,532 compared to 157,900 is,
= 900000/900.
= 1000 times.

Calculate the marked price (original price) if
a. After 25% discount, the price of an article is Rs 7500,
Answer:
Step-by-step explanation:
let original price of an article be x
marked price(price after discount )=Rs 7500
discount%=25%
discount =discount % of cost price
=25/100*x
=25x/100
=x/4
Mark price=original price-discount amount
Rs 7500=x-x/4
Rs 7500=4*x-x/4
Rs 7500*4=4x-x
Rs 30000=3x
Rs 30000/3=x
Rs10000=x
therefore original price of an article is Rs 10000.
