9 - 4(2x - 1) = 45 please help

ddd [48]

Answer:

$x=-4$

Step-by-step explanation:

$9-4(2x-1)=45$

First, we expand the equation using the distributive rule:

$x(y-z)=xy-xz$

Hence, $9-4*2x-4*-1=45$

Simplify: $9-8x+4=45$

Add like terms:

$13-8x=45$

Subtract 13 from both sides: $-8x=32$

Divide both sides by -8:

$x=-4$

Suppose S and T are mutually exclusive events. Find P(S or T) if P(S) = 8/9 and P(T) = 1/10.

blsea [12.9K]

Answer:

$\textbf{$P(S \cap T) = \frac{89}{90}$ }\\$

Step-by-step explanation:

$\textup{Mutually events are events that cannot occur at the same time.}\\\textup{When you toss a coin you get only $head$ or only $tail$ but never both.}\\ \textup{In mathematical terms $P(A) \cup P(B) = 0$, where $A$ and $B$ are mutually exclusive events. }\\\textup{We know the formula:}\\$$ P(A \cup B) = P(A) + P(B) - P(A \cup B) $$\\\textup{When $A$ and $B$ are mutually exclusive, it will simply be:}\\$$ P(A \cup B) = P(A) + P(B) $$\\\textup{Now given:}\\ $P(S) = 8/9$ , $P(T) = 1/10$\\$

$\implies P(S \cup T) = \frac{89}{10}$

What is the answer to 5/8 . 2/7 and what does the dot stand for the dot is actually a little higher

Illusion [34]

First, the dot stands for the "product". You have to multiply.

5/8* 2/7
= [5/ (2*4)]* (2/7)
= 5/4* 1/7 (because 2 and 2 cancel out)
= (5*1)/ (4*7)
= 5/28

The final answer is 5/28~
