Answer:
29.
Step-by-step explanation:
We know that all functions of any angle must add up to be 180 degrees. using this knowledge we take 54 and subtract it by 180.
That leaves us with 126.
We can safely assume the measurement of angle B, using the angle measured as 97.
This is due to the law of corresponding angles.
97 and angle B; correspond, so they must measure the same.
our sum of 126 subtracted by angle B (97) leaves us with the sum of 29.

Given the five number summary, christina has scored 70 marks which is equal to the median of the test scores, therefore about [tex]\frac{1}{2}[/tex] class scored higher than her and [tex]\frac{1}{2}[/tex] class scored lower than her, making option (d) correct.
The five number summary is the descriptive summary of a data where in you are provided the lowest observation, first quartile, median, third quartile and the maximum observation.
Here, the first quartile is the observation which lies at a point in the ordered data that 25% observations are lesser than it and 75% are greater than it.
the median is the observation which lies at a point in the ordered data that 50% observations are lesser than it and 50% are greater than it.
the third quartile is the observation which lies at a point in the ordered data that 75% observations are lesser than it and 25% are greater than it.
As given in the data,
Christina's marks = 70
median marks = 70
christina's marks = median marks
therefore, by definition of median, about half class scored lower than christina and half more than her.

From the given graph, the curve with the shaded dot shows less than or equal to because the dot indicates that the maximum input value of x is at that point.
Secondly, the curve without a shaded dot shows that the input function of x is only greater than 3.
Looking at the options, option A is right and we will prove it thus;
for y = x³ - 3
At x = 2, we see that;
y = 2³ - 3
y = 5
This corresponds with the given equation
For the second curve, for y = x² + 6;
At x = 2, we have;
y = 2² + 6
y = 4 + 6
y = 10
This corresponds with what is given and is thus correct.

Answers
Answer:
£24.26 (rounded to 2dp) or full answ £24.255
Step-by-step explanation:
find 1% of 22.05= 0.2205
0.2205*10=2.205(10%)
add this to the 90%(£22.05+2.025)= 24.255
=24.26(rounded to 2dp)
The price of the lamp before the reduction will be £24.5.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The sale price of the lamp = £22.05
This is a 10% reduction of the normal price.
Now,
Let the price of the lamp before the reduction = x
So, We can formulate;
⇒ x - (10% of x) = £22.05
⇒ x - 10x/100 = £22.05
⇒ (100x - 10x)/100 = £22.05
⇒ 90x / 100 = £22.05
⇒ 90x = £22.05 x 100
⇒ 90x = £2205
⇒ x = £2205/90
⇒ x = £24.5
Thus, The price of the lamp before the reduction will be £24.5.

The area of most three-dimensional geometric shapes is
A = a · h
Area = area of the base · height of the figure.
In this case, the area of the base is the area of a circle, so a = πr²:

a = 100π ≅ 314
Now, all we have to do is multiply the area of the base to the height:

Answers
40 - 40% = 24

$25.44
Step-by-step explanation:
First, you multiply, 5*8 = $40.00
Then you subtract the discout, 40-40% = $24.00
Lastly, you must add the sales tax, 24+6% = $25.44

Turnips
Cabbage
Leeks
Spinach
Carrots
Kale
Turnips
Sammy and Hannah both want to get leeks as their star ingredient. Sammy will draw first, followed by Hannah.
What is the probability that NEITHER contestant draws leeks?
Round your answer to two decimal places.
Answers
The probability that neither of them draws the Leeks card is P = 4/6 = 0.667
Here we can assume that all the cards have the same probability of being randomly drawn.
The cards are:
Cabbage Spinach Kale Leeks Carrots TurnipsSo we have 6 cards. We want to find the probability that neither contestant draws the "Leeks" card.
Sammy draws first, the probability of drawing the Leeks card will be equal to the quotient between the number of Leeks cards (one) and the total number of cards (6).
Then the probability of drawing the leeks card is p = 1/6
This means that the probability of NOT drawing the leeks card is:
q = 1 - 1/6 = 5/6.
Now draws Hanna, now there are 5 cards in the deck (because one was already drawn). With the same approach as before, the probability of drawing the Leeks card is p = 1/5, then the probability of NOT drawing the card is:
q = 1 - 1/5 = 4/5.
The joint probability (this is, the probability of both of these events to happen together) is just the product of the individual probabilities.
Then the probability that neither of them draws the Leeks card is:
P = (4/5)*(5/6) = 4/6 = 0.667
