Answer:

Step-by-step explanation:

Simplify \frac{4}{5}G

G to \frac{4G}{5}

\frac{4G}{5}+42=2.8G+18

+42=2.8G+18

Multiply both sides by 5.

4g + 210 = 14g + 90

Simplify

14G + 90 - 4G to 10G + 90

Subtract 90 from both sides.

210-90=10G210−90=10G

Simplify 210-90210−90 to 120120.

120=10G120=10G

Divide both sides by 1010.

\frac{120}{10}=G

120

Simplify \frac{120}{10}

120

to 1212.

12=G12=G

Switch sides.

G=12G=12

The table gives the relative frequencies of recipes that contains sugar and salt, contain at least one of those ingredients, or

tigry1 [53]

Answer-

The probability that a randomly selected recipe does not contain sugar, given that it contains salt is 22.4%

Solution-

The given table in the link shows the relative frequencies of recipes that contains sugar and salt, or contains at least one of those ingredients, or contains neither of those ingredients.

We have to find the conditional probability that the recipe doesn't contain sugar, given that it contains salt.

We know that, the conditional probability of occurrence of A given that B occurs is,

$P(A|B)=\frac{P(A\ and\ B)}{P(B)} =\frac{P(A\bigcap B)}{P(B)}$

$P(\text{Doesn't contain sugar}\ |\ \text{Contains salt})=\frac{P(\text{Doesn't contain sugar}\ and\ \text{Contains salt})}{P(\text{Contains salt})}$

$P(\text{Doesn't contain sugar}\ and\ \text{Contains salt})=\frac{0.15}{1} =0.15\\P(\text{Contains salt})=\frac{0.67}{1}=0.67$

Putting these values,

$P(\text{Doesn't contain sugar}\ |\ \text{Contains salt})=\frac{0.15}{0.67} =0.224=22.4\%$

How can i solve this (x+2)(2x+3) step by step please

MrRissso [65]

Answer:

2x² + 7x + 6

Step-by-step explanation:

To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).

You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.

(x+2)(2x+3)

2x²+ 3x + 4x + 6

2x² +7x + 6

PLEASE ANSWER this question ty lol

Damm [24]

Answer:

$\huge\boxed{\text{(A) 2 units left and 4 units up}}$

Step-by-step explanation:

You were right!

If we want to transform figure ABCD onto figure A'B'C'D', we need to note that no dilation/rotation/reflection is needed. They're just units apart.

Let's focus on a specific point, as when we move that the whole figure will too.

Let's do B/B'.

We can see that in figure ABCD, point B is at (1, -1). On A'B'C'D', point B' is at (-1, 3).

Lets first change the x values.

What we need to ask is - what's the distance from 1 to -1? We know that from 1 to 0 is 1 point and from 0 to -1 is another 1 point. So, 1+1 = 2. It's a 2 point difference to a smaller number. So we move left.

Same logic applies for y values. What's the difference from -1 to 3? From -1 to 0 is 1 unit, and from 0 to 3 is 3 units. So, the difference is 4 units upwards.

So, 2 units left and 4 units up.

Hope this helped!
