Answer: 7/10

Step-by-step explanation:

write it as a fraction, .7/1

For every number after the decimal, multiply the numerator and the denominator by ten. In .7 there is one number after the decimal, the seven.

.7 x 10

----

1 x 10

.7 becomes 7 and 1 becomes 10. That can't be reduced at all so the answer is 7/10.

Which are the solutions of x2 = 19x + 1?

Finger [1]

Answer:

$(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})$

Step-by-step explanation:

we have

$x^2=19x+1$

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-x^{2}-19x-1=0$

$a=1\\b=-19\\c=-1$

substitute in the formula

$x=\frac{-(-19)\pm\sqrt{-19^{2}-4(1)(-1)}} {2(1)}$

$x=\frac{19\pm\sqrt{365}} {2}$

$x=\frac{19+\sqrt{365}} {2}$

$x=\frac{19-\sqrt{365}} {2}$

$(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})$

therefore

StartFraction 19 minus StartRoot 365 EndRoot Over 2 EndFraction comma StartFraction 19 + StartRoot 365 EndRoot Over 2 EndFraction

Translate this sentence into an equation: 162 is the product of 9 and Gall's age. Use the variable g to represent Gall's age.

oksano4ka [1.4K]

The equation is
9 × g = 162
9g = 162

Solving foe Gall's age,
9g = 162
g = 162 ÷ 9
g = 18

a sequence is defined by ths formula (n+1)=f(n)+3 the first term of the sequence is -4 what is the next term in the sequence

jenyasd209 [6]

How I understand from your writing next term is equal previous plus 3,
if 1st is -4, then next (second) should be -4+3= -1

Identify the question that is NOT statistical.

dusya [7]

A statistical statement is the one that deals with a group of data that is collected from a population or a sample population.

Here when you look the statements B,C and D, you can see that it mentions a group of people or data like time, number etc.

But the statement A does not deal with the population, but it deals with one single person who won the competition. Hence this is the statement that is not statistical
