4x + 6 = 9 is the equation
This is an awful question. They mean to say the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.
Inverse variation means the product is a constant, we'll call it k.
ht = k
When h = 1 hour t=6 minutes
(1)(6) = k
k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)
Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.
ht = k
h = k/t = 6/5 = 1.2 hours
Answer: 1.2 hours, second choice
Answer:
17-2*3-8=3
Step-by-step explanation:
We have given:
17_2_3_8=3 insert + - × or ÷ symbols to make each statement true?
<u>Solution:</u>
We will insert multiplication sign between 2 and 3 and then subtract all the terms
<u>17-2*3-8=3</u>
We will solve it according to the DMAS rule:
DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction. Without DMAS rule all mathematical equations will come up with different answers.
Lets solve the expression and check whether the L.H.S = R.H.S
17-2*3-8=3
17-6-8=3
11-8=3
3 =3
<em>Be sure to multiply first and then subtract</em>
⇒You can also insert addition sign in place of multiplication. It will give the same answer
Answer:
a
The percentage is
b
The probability is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The variance is 
The range consider is 
The value consider in second question is 
Generally the standard deviation is mathematically represented as
substituting value
The percentage of a cucumber give the crop amount between 778 and 834 kg is mathematically represented as
Generally 
So
From the z-table the value for 
and 
So
The percentage is
The probability of cucumber give the crop exceed 900 kg is mathematically represented as
substituting values
From the z-table the value for
