Answer:

You want the average of three scores to be at least 80:

(88 + 78 + x)/3 ≥ 80

88 + 78 + x ≥ 80(3)

166 + x ≥ 240

x ≥ 74

You must make at least 74 on the 3rd test to maintain an average of at least 80%

Answer:

a. 3 cm

b. 6 km

Step-by-step explanation:

to be completely honest, I just shoot my answer based on the pattern.

if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km

Step-by-step explanation:

Use ratios to solve it

a)

x = 4*4/5 = 3.2 cm

b)

x = 5*5/4 = 6.25 km

Answer: 1 4/21

Step-by-step explanation:

6/7+1/3= 25/21= 1 4/21

Step-by-step explanation:

[tex]\frac{6}{7}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{25}{21}[/tex]

Simplify

[tex]\frac{25}{21}[/tex] = 1 [tex]\frac{4}{21}[/tex]

According to the rule, the table is:

x|y

2|3

3|5

4|7

The translation of the rule to a math expression is:

[tex]y = 2x - 1[/tex]

Then, for x = 2:

[tex]y = 2(2) - 1 = 4 - 1 = 3[/tex]

For x = 3:

[tex]y = 2(3) - 1 = 6 - 1 = 5[/tex]

For x = 4:

[tex]y = 2(4) - 1 = 8 - 1 = 7[/tex]

Thus, the table is:

x|y

2|3

3|5

4|7

Answer:

-12

Step-by-step explanation:

F(T)=2(1×+1)

2(1×+1)= x2 + 2, and since we were trying to find what f is, we know know f=2 because of the equation 2(1×+1), so, 2(-6)= -12

Answer:

B

Step-by-step explanation:

When you are subtracting a negative, it is the same as just adding a positive.

[tex]-9\frac{2}{7} + 10\frac{3}{7}[/tex]

We can rearrange the problem to read:

[tex]10\frac{3}{7} -9\frac{2}{7}[/tex]

Now, we can subtract the numbers and fractions separately.

[tex]10+\frac{3}{7} -(9+\frac{2}{7})[/tex]

[tex](10-9)+(\frac{3}{7}-\frac{2}{7} )=1+\frac{1}{7}=1\frac{1}{7}[/tex]

This is B

Answer:

About 7 minutes

Step-by-step explanation:

3 minutes + 4 minutes= 7 minutes memory used for two songs

If 7 seeds are planted, the probability that exactly 3 do grow is;

P(X = 3) = 0.0002

This is a binomial probability distribution problem where;

P(X = x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾

We are given;

p = 95% = 0.95

q = 1 - p

q = 1 - 0.95

q = 0.05

Thus If 7 seeds are planted, the probability that exactly 3 do grow is;

P(X = 3) = ⁷C₃ × 0.95³ × 0.05⁽⁷ ⁻ ³⁾

P(X = 3) = 35 × 0.857375 × 0.00000625

P(X = 3) = 0.000187

To four decimal places gives;

P(X = 3) = 0.0002
