Whoever checks my work and tell what I did wrong and the right answer will

gulaghasi [49]

Answer:

See below

Step-by-step explanation:

I believe that you only had to do letters F, H, and J. In that case, let's go over each one!

F: For isolating $d_{1}$ , we need to get rid of the 1/2 first. Let's multiply each side by 2:

$2*m = 2*\frac{1}{2}(d_{1}+ d_{2}) \\2m = d_{1}+ d_{2}$

After this, we just subtract $d_{2}$ from each side to get $d_{1}=2m- d_{2}$ . Dark Blue is correct! Let's now plug in those numbers below:

$d_{1}=2(10)- 13 = 20-13=7$

G: Let's isolate the vw^2 on one side by subtracting y from each side:

$vw^{2} +y-y=x-y\\vw^{2}=x-y$

Let's now divide each side by v, then put each side under a square root to get our final answer:

$\frac{vw^2}{v} = \frac{x-y}{v}\\ w^2 = \frac{x-y}{v}\\\sqrt{w^2} = \sqrt{\frac{x-y}{v}} \\w=\sqrt{\frac{x-y}{v}}$

Orange is correct! Again, let's solve the problem underneath:

w= $w=\sqrt{\frac{38-(-7)}{5}} = \sqrt{\frac{38+7}{5}} = \sqrt{\frac{45}{5}}=\sqrt{9}=3$

H: This one has some stuff that we haven't worked with quite yet (like terms), but our approach is the same: isolate c on one side of the equation.

$2a-2a+3c=17a-2a+21\\3c = 15a+21\\\frac{3c}{3} = \frac{15a+21}{3}\\c = \frac{15a}{3}+ \frac{21}{3} \\c = 5a+7$

Purple is correct! Let's solve the problem:

$c = 5(\frac{16}{5})+7 = 16+7 = 23$

Answer:

1. The probability that the T-shirt will be grey :-

=》

$\frac{2}{20}$

=》

$\frac{1}{10}$

=》

$0.1$

hence, the probability of grey t-shirt is 0.1

2. The probability that the T-shirt will not be red :-

=》

$1 - \frac{4}{20}$

=》

$1 - \frac{2}{10}$

=》

$1 - 0.2$

=》

$0.8$

The probability that the T-shirt will not be red is

0.8

3. He takes one of his blue T-shirts at random.

What is the probability that the T-shirt is light blue

total blue t-shirts = 5

so, the probability of choosing light blue t-shirt is

=》

$\frac{1}{5}$

=》

$\frac{2}{10}$

=》

$0.2$

hence, the probability of choosing light blue t-shirt is 0.2
