-6/7 = -0.85
-31/50 = -0.62
So -0.62 is greater than -0.85
-0.62 < -0.85
Because the bigger the fraction is the less it actually is and I think the same goes for decimals . Hope I helped
Such an equation would be y + 8x = - 25 (standard form) OR y = -8x - 25 (y-intercept form)
Deriving The Answer:
By using the point-slope form of the equation of a line, by knowing the gradient of that line and a point on that line, the equation of this line can be derived.
Now, the point-slope form exists as y - y₁ = m ( x - x₁)
since slope = -8 and the point on the line = (-4 , 7)
Then m = - 8
x₁ = - 4
y₁ = 7
⇒ y - 7 = -8 ( x - (-4))
⇒ y - 7 = -8x - 32
⇒ y + 8x = - 25
Answer:
Choosing a boy randomly in a class of 10 boys and 10 girls
Step-by-step explanation:
The probability of choosing a boy randomly in a class of 10 boys and 10 girls is calculated as;
(number of boys)/ (total number of students in the class)
= 10/(10+10) = 10/20 = 1/2
The probability of drawing a heart randomly out of a pile of 4 hearts and 8 spades is calculated as;
4/(4+8) = 4/12 = 1/3
The probability of correctly choosing a random number between 1 and 10 is simply 1/10 since the numbers are have a uniform distribution and thus equally likely to be selected.
The probability of choosing a girl randomly in a class of 8 girls and 12 boys is calculated as;
(number of girls)/ (total number of students in the class)
= 8/20 = 2/5
Thus choosing a boy randomly in a class of 10 boys and 10 girls is the event which has a probability closest to 1.
Answer:
blue
Step-by-step explanation:
because there are about a thousand different shades of blue
Responda:
1.) 6;
2.) d) O pai tem 36 anos e o filho tem 12 anos.
Explicação passo a passo:
1.)
Dada a equação: 3x - 4 = 14
3x = 14 + 4
3x = 18
Divida os dois lados por 3
x = 6
2) Dado que ;
Idade do pai = 3 vezes a idade do filho
Idade do pai + idade do filho = 48
Deixe a idade do pai = f; idade da criança = c
Matematicamente ;
f = 3c - - - (1)
f + c = 48 - - - - (2)
Substitua f = 3c em (2)
3c + c = 48
4c = 48
c = 48/4
c = 12
Substitua c = 12 em (2)
f + 12 = 48
f = 48 - 12
f = 36
Portanto ;
Idade do pai = 36 Idade da criança = 12
