Probability that he chooses two different types of biscuits is 53.65 %.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Given
Total biscuits, n = 8
Digestive biscuits = 5
Chocolate biscuits = 3
There are two patterns to chose two different biscuits; a digestive then a chocolate or a chocolate and then a digestive.
∴ The probability of choosing a digestive then a chocolate
= [tex]\frac{5}{8}\times\frac{3}{7}[/tex]
= [tex]\frac{15}{56}[/tex]
= 0.267
The probability of choosing chocolate and then a digestive.
= [tex]\frac{3}{8} \times\frac{5}{7}[/tex]
= [tex]\frac{15}{56}[/tex]
= 0.267
Hence, The combined probability
= [tex]\frac{15}{56}+ \frac{15}{56}[/tex]
= [tex]0.536[/tex]
= 53.6 5 %
Probability that he chooses two different types of biscuits is 53.65 %.

Answer:
x = 12 or 12:204
Step-by-step explanation:
You have to set it up like this....
Just cross multiply.
[tex]\frac{3}{51}*\frac{x}{204}[/tex]
You'll multiply
3*204 = 612
51*x = 51x
612 = 51x (divide by 51 on both sides)

Write the equation for a line containing the point (0,2) and a slope of -7 (y=mx+b)
Answer:
[tex]y=-\frac{7}{1}x+2[/tex]
Step-by-step explanation:
The slope of -7=
[tex]-\frac{7}{1}[/tex]
so fractional slope is
[tex]y=mx+b[/tex]
Substituting slope into a fraction,
[tex]y=-\frac{7}{1} x+b[/tex]
Point is 0,2 so substitute in x and y.
[tex]2=-\frac{7}{1} (0)+b[/tex]
Solve the equation.
[tex]b=2[/tex]
So the equation for the line is
[tex]y=-\frac{7}{1}x+2[/tex]

6k ÷ 7 = -3
Solve for k
Answer:
k = -3.5
Step-by-step explanation:
6k ÷ 7 = -3
Multiply 7 to both sides
6k = -21
Divide both sides by 6
6k/6 = -21/6
k = -3.5
To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.
6(-3.5) ÷ 7 = -3
-21 ÷ 7 = -3
-3 = -3
-3 equals -3 so it is correct that k = -3.5

Answer:
$5.05

A student who is training for a distance race jogged for thirty minutes and covered a distance of 7.5 km. What is the average speed of the student?
Answer:
Average speed is 15km/hStep-by-step explanation:
Step one:
given data:
total distance =7.5km
time taken= 30 min= 0.5 hours
we know that the average speed is the average distance divided by time taken
Step two:
mathematically expressed as
speed=distance/time
substituting we have
speed=7.5/0.5
speed=15km/hour
Hence the average speed is 15km/h
what the slope of(-4,4) (-9,6)
Answer:
-2/5
Step-by-step explanation:
1. 4-6 = -2
2. -4- -9 = 5
3. -2/5
Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
slope formula is:
[tex]y2-y1/x2-x1[/tex]
so we plug in the coordinates
[tex](6-4)/(-9--4)[/tex]
which is
[tex]2/-5[/tex]
so the slope is
[tex]-\frac{2}{5}[/tex]

Consider the figure shown below. Find the value of BL
Answer:
BL = 2
Step-by-step explanation:
Given:
AL = 3
AC = 10
BC = 9
AL = AM = 3 (tangents drawn form am external point)
CM = AC - AM
CM = 10 - 3
CM = 7
CM = CN = 7 (tangents drawn form am external point)
BN = BC - CN
BN = 9 - 7
BN = 2
BN = BL = 2 (tangents drawn form am external point).
BL = 2
