Let

n-------> the number of tomatoes Jolie had before she made her salad

c------> the number of tomatoes left after the salad is made

we know that

Jolie uses 2 tomatoes every day to prepare her salad

c=n-2

therefore

<u>the answer is</u>

The equation that represents the number of tomatoes Jolie has after she made her salad is equal to

c=n-2

2. <br> Find the area of the region bounded by the graphs of y = -x2 + 3x + 4 and y = 4. (5 points)
Kipish [7]

Answer:

4.5 sq. units

Step-by-step explanation:

area = -⅓x³+3/2 x² ] 0 to 3

= -⅓(3)³+ 3/2 (3)² -0

= -9 + 27/2

= -9 + 13.5

= 4.5 sq. units

Hey, Please help!!
Mazyrski [523]

Step-by-step explanation:

1. d = rt

Divide t from both sides.

\frac{d}{t} = r

2. PV = nRT

Divide P from both sides.

V = \frac{nRT}{P}

3. \frac{x}{2} -g=a\\

Add g to both sides.

\frac{x}{2} = g + a

Now multiply by 2 on both sides.

x = 2(g + a)

(or, x = 2g + 2a)

4. g(h+\frac{3}{2} ) = 11

Divide g from both sides.

h + 1.5 = \frac{11}{g}

Now subtract 1.5 from both sides.

h = \frac{11}{g} -1.5

5. a(n-2)+5=bn\\

n = \frac{2a-5}{a - b}

The makers of a smartphone have received complaints that the face recognition tool often doesn't work, or takes multiple attempt
cupoosta [38]

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the new version and the old version. The population proportion of the time that the tool works for the new and old version would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of the times that the tool works for the new and old version

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

H1 : p1 > p2

p1 - p2 > 0

it is a right tailed test

Sample proportion = x/n

Where

x represents number of success

n represents number of samples

For new version

p1 = 70/100 = 0.7

n1 = 80

x1 = n1p1 = 80 × 0.7 = 56

For old version,

p2 = 56/100 = 0.56

n2 = 75

x2 = n2p2 = 75 × 0.56 = 42

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (56 + 42)/(80 + 75) = 0.63

1 - pc = 1 - 0.63 = 0.37

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.7 - 0.56)/√(0.63)(0.37)(1/80 + 1/75) = 0.14/0.07759993557

z = 1.8

Since it is a right tailed test, we will look at the area to the right of the z score on the normal distribution table to determine the p value. Therefore,

p = 1 - 0.9641 = 0.04

By using the p value,

Since 0.1 > 0.04, we would reject the null hypothesis. Therefore, at a significance level of 0.1, it can be concluded that the new version is performing better.
