Answer:

11/16

Step-by-step explanation:

P(TTHH) = 4C2*(1/2)^4 = 4!/2!*2!*(1/2)^4=6/16  

Total Probablity = 1/16 + 4/16 + 6/16

=11/16

Answer:

does not represent a linear function.

Step-by-step explanation:

For the function to be linear, the slope must be the same for every poknt along the function. If is not, then is not a linear function.

Let us now calculate the slope;

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

We shall take the first two points

[tex]m = \frac{4 - 2}{2 - 1} \\ m = \frac{2}{1} \\ m = 2[/tex]

Next we shall take the 2nd and 3rd points

[tex]m = \frac{8 - 4}{3 - 2} \\ m = \frac{4}{1} \\ m = 4[/tex]

The slope is not the same for these two different point, hence this table does not represent a linear function.

Answer:

60 grams sugar for 15 biscuits.

3x60 grams of flour, so 180 grams for 15 biscuits.

60÷15= 4 batches.

4 batches with 180 grams each- 4 x 180= 720 grams of flour.

Answer:

[tex]23^{o}[/tex] and [tex]23^{o}[/tex]

Step-by-step explanation:

An isosceles triangle has two of its sides and angles to be equal. Let each of the unknown equal angles be represented by x. Since one of its angles measures  134°, then;

x + x +  134° = [tex]180^{o}[/tex]

2x + 134° = [tex]180^{o}[/tex]

2x = [tex]180^{o}[/tex] - 134°

    = 46

x = [tex]\frac{46}{2}[/tex]

  = [tex]23^{o}[/tex]

x = [tex]23^{o}[/tex]

The other angles that could be in the isosceles triangle are [tex]23^{o}[/tex] and [tex]23^{o}[/tex].

Answer:The answer should be D based on the data given.

Step-by-step explanation:

Answer:

d

Step-by-step explanation:

x° = 118°

y° = 180° - (22° + 180° - x°)

y° = 180° - (22° + 180° - 118°)

y° = 180° - 22° - 180° + 118°

y° = 118° - 22°

y° = 98°

Answer:

g > 8

Step-by-step explanation:

25g > 200, so divide 200 by 25, and you get 8. Since the original symbol was >, keep it.

Answer:

$480 total or 80$ in interest

Step-by-step explanation:

5 percent of 400 is 20

20 x 4 = 80

400+ 80= 480

he will make $480 after 4 years

Answer:

m = [tex]\frac{y-q}{x}[/tex]

Step-by-step explanation:

Given

y = mx + q ( subtract q from both sides )

y - q = mx ( divide both sides by x )

[tex]\frac{y-q}{x}[/tex] = m

Answer:

The time now is 7 pm

Step-by-step explanation:

Suppose that now is the time T.

We know that:

"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".

Then:

if we define midnight as 12, and we assume that T is in the pm range.

Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))

With this in mind, we can write the problem as:

12 - (T + 4) = (1/4)*( 12 - (T + 1))

Now we can solve this for T.

12 - T - 4 = (1/4)*(12 - T - 1)

8 - T = (1/4)*(11 - T)

4*(8 - T) = 11 - T

32 - 4*T = 11 - T

32 - 11  = -T + 4*T

21 = 3*T

21/3 = T

7 = T

Then T = 7 pm

The time now is 7 pm

Answer:

5.6715 * 10^26 kg

Step-by-step explanation:

Given that :

Mass of earth = 1/95 the mass of saturn

If Mass of earth = 5.97 x 10^24 kg

Let the mass of saturn = x

5.97 x 10^24 kg = 1/95 * x

5.97 x 10^24 kg = x / 95

x = 95 * 5.97 x 10^24 kg

x = 567.15 * 10^24

x = 5.6715 * 10^26 kg

Mass of saturn = 5.6715 * 10^26 kg

Answer:

7/24

Step-by-step explanation:

I converted all of the denominators to a common one: 24

15/24 + 6/24 - 14/24 is the new equation

21/24 - 14/24= 7/24

Answer:

4/7

Step-by-step explanation:

Answer:

33% of the grid is not shaded.

67% of the grid is shaded.

67/100 of the grid is shaded.

Answer:

Angie originally has $75 on her card.

She only uses the card for a daily cup of tea of $2.85

Then the equation:

y = $75 - $2.85*x

represents the balance on the card after x cps of tea.

a) The x-intercept is the pair (x, 0), meaning that y = 0, so this is the point at which the balance of the card is zero.

Here we need to solve:

0 = $75 - $2.85*x

$2.85*x = $75

x = $75/$2.85 = 26.3

Here we have a particular case because she can not buy 0.3 of a cup of tea, so the card will never reach a balance of $0.

The y-intercept is the pair (0, y) so we have x = 0, then: y = $75 - $2.85*0 = $75

This is the initial balance of the card.

b) Here we need to solve

y = $35 = $75 - $2.85*x

for x

$35 = $75 - $2.85*x

$35 + $2.85*x = $75

$2.85*x = $75 - $35 = $40

x = $40/$2.85 = 14.03

So after 14 cups of tea, the card's balance will be near $35.
