Answer:

fourth option

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values

sin60° = $\frac{\sqrt{3} }{2}$ , cos60° = $\frac{1}{2}$ , then

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{4\sqrt{2} }$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2x = 4 $\sqrt{6}$ ( divide both sides by 2 )

x = 2 $\sqrt{6}$

---------------------------------------------------------

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{4\sqrt{2} }$ = $\frac{1}{2}$ ( cross- multiply )

2y = 4 $\sqrt{2}$ ( divide both sides by 2 )

y = 2 $\sqrt{2}$

Answer:

a) F(2)=0.30

b)P(X>3)=0.7

c)P(2≤X≤5)=0.67

d)P(2<X<5)=0.71

Step-by-step explanation:

a) F(2)=P(X≤2)=0.30

F(2) is given in the probability distribution

b) P(X>3)=1-P(X≤2)=1-F(2)=1-0.3=0.7

P(X>3)=0.7

c)P(2≤X≤5)=?

As we know that P(a≤X≤b)=F(b)-F(a)=P(X≤b)-P(X≤a)

So,

P(2≤X≤5)=P(X≤5)-P(X≤2)=F(5)-F(2)=0.97-0.3=0.67

P(2≤X≤5)=0.67

d)P(2<X<5)=P(1≤X≤4)=P(X≤4)-P(X≤1)=F(4)-F(1)=0.91-0.2=0.71.

P(2<X<5)=0.71

Please help with system of equations formula creation.

jasenka [17]

Answer:

The cooperative has to make 70 shirts per day.

Step-by-step explanation:

Let x shirts be the number of shirts in a day the cooperative has to make to fulfill his plan.

In 8 days, it will make 8x shirts.

Everyday, overfilling the norm by 10 shirts, the cooperative makes x + 10 shirts in a day.

The cooperative fulfilled his plan in 1 day less, so it spent $8-1=7$ days and made $7(x+10)$ shirts.

The number of shirts is the same, so

$8x=7(x+10)\\ \\8x=7x+70\\ \\8x-7x=70\\ \\x=70$

The cooperative has to make 70 shirts per day.
