A box of chocolates contains five milk chocolates, five dark chocolates, and three white chocolates. You randomly select and eat three chocolates. The first piece is milk chocolate, the second is white chocolate, and the third is milk chocolate.

Because the p-value is less than 0.05, the mean fitness scores for the two groups of students are significantly different

========================================================

Explanation:

Use a T calculator to find that P(T > 2.63) = 0.00459 approximately when we have 209 degrees of freedom.

Double this to get 2*0.00459 = 0.00918 and this is the approximate p-value

Since the p-value is less than alpha = 0.05, this means we reject the null and conclude that the two population means are significantly different.

Answer:

x = -5

Step-by-step explanation:

Given:

[tex]\displaystyle \large{8x-5=5(x-4)}[/tex]

Distribute 5(x-4):

[tex]\displaystyle \large{8x-5=5x-20}[/tex]

Add both sides by 5:

[tex]\displaystyle \large{8x-5+5=5x-20+5}\\\displaystyle \large{8x=5x-15}[/tex]

Subtract both sides by 5x:

[tex]\displaystyle \large{8x-5x=5x-15-5x}\\\displaystyle \large{3x=-15}[/tex]

Divide both sides by 3:

[tex]\displaystyle \large{\dfrac{3x}{3}=\dfrac{-15}{3}}\\\displaystyle \large{x=-5}[/tex]

Therefore, your solution is x = -5

Answer:

x = -5

Step-by-step explanation:

Distributing the value in the RHS

Equating to the RHS

Bring x terms to the left and numbers to the right.

Divide both sides by 3.

Answer:  [tex]\bold{x=\frac{2 \sqrt{10}}{7}}[/tex]

Step-by-step explanation:

[tex]\text { Let } p=\left(x,-\frac{3}{7}\right) \text { as given } y \text {-coordinate is }=-\frac{3}{7}[/tex]

[tex]r=1 \ \ \text{(as $p$ is on unit circle)} \\$$\therefore x^{2}+y^{2}=1^{2}[/tex]

[tex]\begin{aligned}&\Rightarrow x^{2}+\left(-\frac{3}{7}\right)^{2}=1 \Rightarrow x^{2}=1-\frac{9}{49}=\frac{40}{49} \\&\Rightarrow x^{2}=\pm \sqrt{\frac{40}{49}} \Rightarrow x=\pm \frac{2 \sqrt{10}}{7}\end{aligned}[/tex]

[tex]$$Since the point is in quadrant $4$ $\therefore \text{the} \ x$-coordinate will be positive$$\therefore x=\frac{2 \sqrt{10}}{7} \text$$[/tex]

Step-by-step explanation:

2√3 / √6                            Multiply top and bottom by √6

(2√3 * √6) / (√6  √6  )       Combine left factors

(2 √18) / (√6  √6  )             (√6  √6  )  = 6

(3 √18) / 6                            Factor 18

(3 √2 * 3 * 3                         Take one 3 outside the brackets. Discard the other three.

Answer: 90°

Step-by-step explanation:

(x°+90°)=180°(being the sum of angles of the triangle)

or, x°= 180°-90°

or x°= 90°

Answer:

8 cm

Explanation:

A = 1/2 × b × h.

28 = 1/2*b*7

56=7b

8=b

Answer:

260 cm²

Step-by-step explanation:

A=b×h

A=b×h=20·13=260

Step-by-step explanation:

solution

b=20 cm

h =13 cm

Area (a) = b ×h

a=20cm ×13 cm

so , a =260 cm square

p = root under (h square - b square)
