Answer:
The mean score for the students is 593.33.
Step-by-step explanation:
The table gives the scores of 6 students from a class of 25 in a competitive exam.
Name : Julia Andrew Jason Cathy Jessica Robert
Score : 650 550 380 720 710 550
Mean = Sum of the data values / Total number of data values
Mean = ( 650 + 550 + 380 + 720 + 710 + 550 ) ÷ 6
= 3560 ÷ 6 =593.33
The mean score for the students is 593.33.

Answer :
Given expression is
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term
Here coefficient of middle term is -7
Half of -7 is
Square of is =
So the expression becomes that gives perfect square trinomial
Hence , the value of 'c' is
The value for c will make the expression a perfect square trinomial is 49/4
The equation is given as:
x^2 - 7x + c
Take the coefficient of x
k = -7
Divide it by 2
k/2 = -7/2
Square both sides
(k/2)^2 = (-7/2)^2
The above represents the value of c.
So, we have:
c = (-7/2)^2
Evaluate
c = 49/4
Hence, the value for c will make the expression a perfect square trinomial is 49/4

The total number of possibilities when you roll a six-sided die and draw a card from a standard 52-card deck is 312.
The question is asking us to calculate the total possibilities when you roll a single six-sided die and draw a card from a standard 52-card deck. In mathematics, to calculate the total possibilities of two independent events happening together, we multiply the number of outcomes of the two events.
A six-sided die has 6 possible outcomes (1, 2, 3, 4, 5, or 6) and a standard 52-card deck has 52 possible cards to draw. Therefore the total possibilities, when you roll a die and draw a card, would be 6 (die outcomes) * 52 (card outcomes) = 312 total possibilities.

Answer:
340
Step-by-step explanation: 200 * .14 = 28 then 28*5= 140 then 140+200=340
Answer:
340 in 5 years
Step-by-step explanation:
I set it up as a fraction so I could find 14% of 200.
14/100 = x/200
Then I cross multiplied
100x = 2800
Simplify
x=28
Twenty-eight is 14% of 200. Multiply 28 by 5.
28 x 5 = 140
Add 140 to 200
340
Answer:
The most reduced ratio equivalent to 26:14 is 13:7.
Step-by-stepExplanation:
In order to reduce a ratio, we find the greatest common divisor (GCD) of the numerator and denominator and divide both by the GCD.
The GCD of 26 and 14 is 2.
Dividing both the numerator and denominator of 26:14 by 2 gives us 13:7.
Therefore, 13:7 is the most reduced ratio equivalent to 26:14.
Answer:
13:7
Step-by-step explanation:
just divide it by 2 it's equivalent
