How do you solve this equation y+7=10

Mathematics

You should just add -7 in both sides of the equation so you gonna have : 
y + 7 = 10 
   -7       -7   
so you gonna have : y = 10- 7  and y = 3 :))
i hope this is helpful 
have a nice day

Subtract from both sides to isolate the variable. (inverse operation)

y+7 = 10
   -7     -7

y = 3

Final answer: y = 3

Given functions f(x)=3x^2, g(x)= x^2-4x+5, and h(x)=-2x^2+4x+1<br> Rank them from least to greatest
Sindrei [870]
Ok, ranked by axis of symmetry

basically x=something is the axis of symmetry
the way to find the axis of symmetry is to convert to vertex form and find h and that's the axis of symmetry

but there's an easier way

for f(x)=ax^2+bx+c
the axis of symmetry is x=-b/2a
nice hack my teacher taught me


so

f(x)=3x^2+0x+0
axis of symmetry is -0/(3*2), so x=0 is the axis of symmetry for f(x)

g(x)=1x^2-4x+5,
axis of symmetry is -(-4)/(2*1)=4/2=2, x=2 is axis of symmetry for g(x)


h(x)=-2x^2+4x+1
axis of symmetry is -4/(2*-2)=-4/-4=1, x=1 is the axis of symmetry for h(x)


0<1<2
axisies
f(x)<h(x)<g(x)

order based on their axises of symmetry is f(x), h(x), g(x)

C. would be the correct device to use in trials.

But the actual probability is:

(1-1/4)^5

243/1024

(about 23.73% chance none of the five chose vanilla)

Answer:

17.5%

Step-by-step explanation:

First of all, see this situation as a cumulative binomial distribution. You have isolated trials with a probability of success. This makes it binomial. The wording of the question "what is the probability of at least half..." makes this cumulative.

There are a few ways to calculate this, and I'm not quite sure which way you're familiar with. I'll show the cumbersome way and use wolfram to make the calculation.

First, I'll calculate the probability for 15 success, given 30 trials.

30c15*0.4^15*0.6^15

Since the question asks for the probability of at least 15 success, I'll have to make a calculation for the probability of 16 successes, then 17, and so on. Then I'll have to add all the probabilities together. So, I'll use wolfram for that (see attached)
